f789ee4ff0 Introduces a track to segment decoder. 
This will be needed to make formats like G64 and HFE writeable, but probably also will be usable to speed up static analysis.

Thomas Harte
b5406b90cd Introduces a new class hierarchy for disk images. 
Increasing independence of format-specific stuff and generic caching without mangling them into a common namespace, and allowing in some cases for a decrease in read/write blocking.

ff24e1de31 Corrects 6522 bridge per has-a-not-is-a template switch. 2017-09-04 21:56:21 -04:00
Thomas Harte
6547102511 Attempts better to hide C1540 implementation details from the reader. 
In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.
 2017-09-04 20:58:00 -04:00
Thomas Harte
24b3faa427 Deconstitutes the 6522 into component parts, templated and non-templated. 
Adjusts the Oric, Vic-20 and C-1540 accordingly, albeit with the quickest possible solutions.

ab2bcb939f Separates 6502Base into its constituent parts. 2017-09-04 11:08:33 -04:00
Thomas Harte
45499050b6 Separates Z80Base.cpp into its component classes. 2017-09-04 11:04:01 -04:00
Thomas Harte
b034d4e6f8 Refactors the Z80 to separate out interface and implementation. 
Following the pattern just established by the 6502, puts all implementation specifics beyond the visibility of a human reading Z80.hpp and in subfolders so as to promote the idea that they shouldn't go out of their way.
 2017-09-01 20:50:24 -04:00
Thomas Harte
b306776ba9 Removes from 6502.hpp all remaining implementation details, making it purely an interface document. 
Though those details remain visible to files including 6502.hpp through necessity.
 2017-09-01 19:46:29 -04:00
Thomas Harte
4af333d5ec Tidies the 6502 template and folder hierarchy. 
Specifically: there's now just the one .h file at the top level, giving a clear indication of what a user should read. That separates implementation from interface. It also devolves a lot more to the base class because doing so makes debug builds less of a hassle. The all-RAM 6502 has been shuffled off into a subfolder, to indicate that it's not something you necessarily need know about. Also general documentation improvements have been applied: incorrect citing of the recurring-template pattern has been removed and the meaning of the two BusHandler methods has now accrued at the bus handler.

f10be2a18a Eliminates potential cyclic entry into CSMachine during its -dealloc. 
Explicit cause: dealloc calls close_output(). That may decide to flush work, indiscriminately. Some of the flushed work might be audio generation. Audio generation might cause the audio queue to react with an out-of-data announcement. Which would cause a fresh attempt to update the CSMachine.

d06031dfcb Removes the options panel for CPC display. 2017-08-27 17:11:35 -04:00
Thomas Harte
4a66dd9e82 Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm. 2017-08-27 16:42:16 -04:00
Thomas Harte
522839143f Revokes -[CSMachine init] and the slightly troubling create-on-demand semantics it places upon subclasses via .machine. Therefore each machine must announce its own implementation of -init. 2017-08-27 16:36:21 -04:00
Thomas Harte
9aa150c338 Abstracts the target platform type out from the static analyser's ownership. 2017-08-27 15:02:13 -04:00
Thomas Harte
7af3de010e Suspected my mode 1 interrupt timing might be off. Reminded myself of the sources. Persuaded myself that it wasn't. Added appropriate comments. 2017-08-23 22:25:31 -04:00
Thomas Harte
ee71be0e7e Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable. 2017-08-21 21:56:42 -04:00
Thomas Harte
49285e9caa Attempted to implement Sleeper in Drive and therefore in DiskController. Also corrected a couple of nonconformant file names. 2017-08-20 11:54:54 -04:00
Thomas Harte
cedb809c21 Sketched out a protocol designed to save processing time on anything that may sleep — probably just disk controllers for now but one can easily imagine it being applicable to printers, and possibly sound chips with suitable changes in guarantee for sound packet receivers. 2017-08-20 10:53:25 -04:00
Thomas Harte
e6683e7f2d Added the base skeletal stuff of HFE support. 2017-08-17 21:48:48 -04:00
Thomas Harte
378f231499 Fully wired in drag-and-drop for media insertion. 2017-08-17 11:00:08 -04:00
Thomas Harte
f68565a33f Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine. 2017-08-17 10:48:29 -04:00
Thomas Harte
4c15e46fd1 Performed the normative removal from public view of Vic-20 implementation details. Which were hefty. 2017-08-16 16:05:30 -04:00
Thomas Harte
75208b0762 Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere. 2017-08-16 15:33:40 -04:00
Thomas Harte
de1c526789 Cut the amount disclosed by the Atari 2600 for public inspection down to the minimum, relocating implementation into the .cpp. 2017-08-16 14:52:40 -04:00
Thomas Harte
148591b7f2 Hid most of the Oric innards, and corrected a potential multi-thread access error emanating from the Mac side of the world. 2017-08-16 14:35:53 -04:00
Thomas Harte
06e31f5102 Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'. 2017-08-16 12:39:15 -04:00
Thomas Harte
3947347d88 Introduces active input handling for the AY and uses it in the CPC to give proper, active keyboard input, rather than push-on-select, which was only ever a temporary hack. Also maps a few more keys for the Amstrad. 2017-08-15 22:47:17 -04:00
Thomas Harte
6cfc3daacb Introduced a test within the disk controller so as not to request illegal tracks from disks, instead automatically substituting an 'unformatted' track. Which is just empty. 2017-08-15 21:52:12 -04:00
Thomas Harte
2d81acb82e Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14. 2017-08-11 19:18:45 -04:00
Thomas Harte
570d25214e Made an initial attempt at typer support for the CPC. 2017-08-11 11:21:07 -04:00
Thomas Harte
6a65c7a52a Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning. 2017-08-10 17:10:21 -04:00
Thomas Harte
ad8c8166bc Built in gamma conversion for all machines, assuming an output of 2.8 for PAL, 2.2 for NTSC. 2017-08-10 15:17:08 -04:00
Thomas Harte
4d60b8801c Started trying to factor out just the PLL stream -> FM/MFM events part that is presently in the WD1770. 2017-08-05 22:26:15 -04:00
Thomas Harte
3e984e75b6 Strung up an empty shell that eventually should contain the 8272, and added appropriate IO decoding to the Amstrad. 2017-08-05 19:45:52 -04:00
Thomas Harte
75c59fefab Added an empty husk to begin support for Amstrad CPC disk image formats. 2017-08-05 10:02:10 -04:00
Thomas Harte
bbb17acf3a Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality. 2017-08-03 11:50:50 -04:00
Thomas Harte
ad3a98387f Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part. 2017-08-03 11:42:31 -04:00
Thomas Harte
681d1e2f8d Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one. 2017-08-02 22:12:59 -04:00
Thomas Harte
6ca07f1e28 I guess it might end up living somewhere else, but introduced a header with the compiler-specific stuff to allow me to force things inline. 2017-08-01 22:04:58 -04:00
Thomas Harte
9d43784c65 Significantly increased quantity of keys forwarded. 2017-08-01 20:37:55 -04:00
Thomas Harte
f5b278d683 Added enough stuff to put the emulated Amstrad CPC in a state of knowing whether its '0' key is pressed. 2017-08-01 17:31:56 -04:00
Thomas Harte
08ad35efd9 It's barely an implementation of the 8255, but ensured that data is bounced into the PortHandler, conveniently assuming the interaction mode used by the CPC. 2017-08-01 16:34:13 -04:00
Thomas Harte
58b98267fc Formally transferred ownership of PIO accesses to an incoming template, and decided to start being explicit about how to specify the interfaces and provide fallbacks for optional behaviour for the new, clean generation of interfaces. A full-project sweep will inevitably occur but I'll try to tie off this branch first. 2017-08-01 16:15:19 -04:00
Thomas Harte
ace71280a0 Removed implementation file; this is only ever going to be a template. 2017-08-01 16:00:17 -04:00
Thomas Harte
2b168f7383 Disabled the address sanitiser as an every-time run again, as it just pushes my computer a bit too far. 2017-07-31 22:32:56 -04:00
Thomas Harte
0536f089e1 Eliminated old-[personal-]fashioned line break. 2017-07-31 22:32:26 -04:00
Thomas Harte
3df13cddd4 As per my keenness for cleanliness improvements corresponding to my ever-increasing C++ ability: turned the Amstrad into something that a factory produces, allowing me completely to hide a bunch of implementation details. 2017-07-31 22:32:04 -04:00
Thomas Harte
68ceeab610 Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation. 2017-07-31 19:56:59 -04:00
Thomas Harte
afd409c883 Ensured that ROM images are loaded and passed to the Amstrad CPC. 2017-07-31 18:44:49 -04:00
Thomas Harte
26b6c03a2a Re-enabled the address sanitiser as a development tool. 2017-07-31 07:30:07 -04:00
Thomas Harte
c0f1313830 Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr CRT. 2017-07-30 22:05:29 -04:00
Thomas Harte
5b5720fac0 Added to the static analyser the most basic through-path for Amstrad CPC content. 2017-07-30 21:15:20 -04:00
Thomas Harte
d25d7d7d40 Added the Amstrad CPC as a named target and declared support for its CDT file format. 2017-07-29 21:56:33 -04:00
Thomas Harte
761afad118 Corrected timestamp return, and its testing by the 6502 timing tests. 2017-07-27 21:19:16 -04:00
Thomas Harte
37950143fc Attempted to nudge wait timing onto half-cycle boundaries, which expands the number of partial machine cycles the Z80 can post but pleasingly also regularises them. Switched the AllRAMProcessor to reporting half cycles by default and corrected all Z80 tests. 2017-07-27 20:17:13 -04:00
Thomas Harte
9257a3f6d7 Added test for 16-bit arithmetic, and fixed implementation. 2017-07-26 19:04:52 -04:00
Thomas Harte
728143247d Added a test for RLD and RRD. Which already passes. 2017-07-26 18:56:35 -04:00
Thomas Harte
6ec4e4e3d7 Merge branch 'master' into Memptr 2017-07-25 23:01:34 -04:00
Thomas Harte
37ccb9d3b6 Fixed 6502 timing tests. 2017-07-25 23:00:39 -04:00
Thomas Harte
3c254360ba Completed fixture of the 6502 BCD test. 2017-07-25 22:55:45 -04:00
Thomas Harte
3ca51bedc6 Discovered legitimate uses of the jam opcode so reinstated it. Corrected illegitimate uses. 2017-07-25 22:48:44 -04:00
Thomas Harte
36076b7ea5 Eliminated final vestige of professed jam handling. This should make it clear which tests still think they can capture jams. 2017-07-25 22:38:26 -04:00
Thomas Harte
279c369a1f Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation. 2017-07-25 22:21:09 -04:00
Thomas Harte
75d67ee770 Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts. 2017-07-25 20:20:55 -04:00
Thomas Harte
df4732be2e Corrected test. 2017-07-24 22:33:49 -04:00
Thomas Harte
9435c1e12a The 1540 is now a ClockReceiver. 2017-07-24 22:32:41 -04:00
Thomas Harte
2912d7055b The 6532 is now a ClockReceiver. 2017-07-24 21:57:24 -04:00
Thomas Harte
13f7aa4063 The TIA is now a ClockReceiver. 2017-07-24 21:48:34 -04:00
Thomas Harte
b3ae920746 Converted the DPLL and disk controller classes to be ClockReceivers. 2017-07-24 21:04:47 -04:00
Thomas Harte
e6578defcd It turns out that quite a few tests still rely on CSTestMachine6502JamOpcode. Though since it no longer works, that'll need to be fixed. In the meantime, fixed the test build process at least, as it's not really what this branch is meant to be invested in. 2017-07-23 22:22:50 -04:00
Thomas Harte
ace8e30818 Bubbled the Z80's move into clock receiver territory up into the Z80 test machine. 2017-07-23 22:21:39 -04:00
Thomas Harte
b0c2325adc Corrected run call, and accepted that jam handling is gone forever. 2017-07-22 22:21:26 -04:00
Thomas Harte
2ff157cf7a Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that. 2017-07-22 22:17:29 -04:00
Thomas Harte
1ba3f262a2 Sketched out a template for clock-receiving components to allow them to be implemented in terms of either half or whole cycles. 2017-07-22 21:46:50 -04:00
Thomas Harte
4ea835e50b Added test for EX (SP), rp, which passes. 2017-07-22 17:17:32 -04:00
Thomas Harte
5fddbec132 Merge branch 'master' into Memptr 2017-07-22 17:06:22 -04:00
Thomas Harte
6633537fb8 Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring. 2017-07-22 16:02:25 -04:00
Thomas Harte
6437c43147 Added CPI and CPD tests: at last two that pass without requiring implementation changes! 2017-07-22 12:38:18 -04:00
Thomas Harte
5928a24803 Transcribed missing tests as TODOs. 2017-07-22 11:44:17 -04:00
Thomas Harte
20a6bcc676 Added tests for the various LD (nn), rr instructions and corrected implementation to pass. 2017-07-22 11:39:13 -04:00
Thomas Harte
eaf313b0f6 Added a test on LD A, (DE) and LD A, (BC), and adjusted implementation to pass. 2017-07-22 11:20:21 -04:00
Thomas Harte
d51b66c204 Expanded test to hit all 65536 possibilities (and not to allocate a fresh Z80 test machine each time, as that's unnecessary and slow), and fixed implementation to pass test. 2017-07-21 23:01:35 -04:00
Thomas Harte
660f0e4c40 Added Objective-C through wiring and a Swift test class for Memptr modifications. So far with a single test, that fails. 2017-07-21 22:52:25 -04:00
Thomas Harte
2b5d0877a8 Adjusted parameter name to match documentation. I think it's a carry-over from before I was passing the whole event along. 2017-07-21 21:27:50 -04:00
Thomas Harte
2a7fc86b15 Enabled stricter warnings. 2017-07-21 20:44:35 -04:00
Thomas Harte
8f72fc4a44 Factored out from the UEF implementation the concept of being a tape that has a queue of pending pulses and manages that queue. 2017-07-16 22:04:40 -04:00
Thomas Harte
238348c885 Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required. 2017-07-16 21:33:11 -04:00
Thomas Harte
7b5f93510b Fixed the DigitalPhaseLockedLoopBridge bridge, once again fixing tests. 2017-07-16 20:55:57 -04:00
Thomas Harte
8ddd686049 Removed redundant variable. 2017-07-16 19:04:03 -04:00
Thomas Harte
2fb0aea990 Updated the C1540 test vessel to the new world. 2017-07-16 17:00:39 -04:00
Thomas Harte
279f4760d7 Eliminated buffer_size_ as something explicitly stored, and reduced size of delegate call out. 2017-07-16 15:01:39 -04:00
Thomas Harte
368bff1a82 Added a shell class that will one day be able to parse CSW files, plus the logic and metadata to instantiate it when a CSW presents itself. 2017-07-10 21:43:58 -04:00
Thomas Harte
3e5c209039 Added basic Typer support for the ZX80 and '81. 2017-07-09 22:00:34 -04:00
Thomas Harte
54efcb7e2f Made a game attempt at automatic motor control and ensured setting is initialised correctly from the user defaults. 2017-07-08 19:31:20 -04:00
Thomas Harte
e2575d6de4 Routed tape motor selections through to the C++ side of the world, and ensured that manual tape playback works properly. 2017-07-08 19:21:12 -04:00
Thomas Harte
23e989e170 This will likely do for the Swift/XIB side of things: the play/pause button is enabled or disabled as per the user's choice of automatic tape control, and toggles function when pressed. It communicates activity down to the Objective-C[++] layer, giving it a route through to the actual machine. 2017-07-08 19:12:06 -04:00
Thomas Harte
28412150e6 Added controls for controlling the tape motor of the ZX80/81, assuming I can find an automatic option. 2017-07-08 17:59:33 -04:00
Thomas Harte
cb105fdeb4 Took a first stab at high-res support. 2017-06-22 22:48:17 -04:00

aec4fd066b I think I've definitively decided against this model of timing. 2017-06-22 21:32:14 -04:00
Thomas Harte
95a6b0f85c Introduced an NMI/wait interrupt timing test, and adjusted the Z80 to conform to information posted by Wilf Rigter. 2017-06-22 21:09:26 -04:00
Thomas Harte
644ef13acd Connected up the fast-tape GUI option for the ZX80 and '81. 2017-06-22 20:20:31 -04:00
Thomas Harte
0e0ce379b4 Renamed MachineCycle to PartialMachineCycle given that it mostly no longer intends to describe an entire machine cycle. 2017-06-21 20:38:08 -04:00
Thomas Harte
36e8a11505 Sought to simplify the way partial machine cycles are communicated, for ease of machine implementation. Also implemented the wait line. 2017-06-21 20:32:08 -04:00
Thomas Harte
108da64562 Fixed LD H, (HL) and LD L, (HL) by ensuring that whatever the subclass does goes to a temporary place before updating the address. Corrected the LD (IX+d), n machine cycle test for my new best-guess timing. This should leave only interrupt timing as currently amiss. 2017-06-20 22:25:00 -04:00
Thomas Harte
184b371649 Attempted to get to 'proper' timing for LD (IX+d),n, albeit that proper is a guess. 2017-06-20 21:48:50 -04:00
Thomas Harte
27ac342928 Corrected conditional call timing, and its test. 2017-06-20 20:57:23 -04:00
Thomas Harte
6752f165db Added failing tests for both kinds of CALL. 2017-06-19 22:03:29 -04:00
Thomas Harte
e05076b258 Added tests for everything except CALL. All passing. 2017-06-19 22:00:04 -04:00
Thomas Harte
fadbfdf801 Added DJNZ test. 2017-06-19 21:31:56 -04:00
Thomas Harte
cb277b8d1e Added JP and JR tests. 2017-06-19 21:27:23 -04:00
Thomas Harte
234f14dbbe Tests were at fault; all passing now. 2017-06-19 21:14:40 -04:00
Thomas Harte
99ede3a9ef BIT/SET (IX+d) were incorrectly encoded. Hence fixed BIT (IX+d). 2017-06-19 21:04:14 -04:00
Thomas Harte
378233f53d Extended to BITs and SETs, accruing three new failures. 2017-06-19 21:01:30 -04:00
Thomas Harte
f903408980 Caught up on comments. 2017-06-19 20:53:22 -04:00
Thomas Harte
b684254908 Introduced further tests down to a failing attempt at RLC (IX+d). Made an initial attempt to fix, failed. 2017-06-19 20:33:34 -04:00
Thomas Harte
351d90ca55 Added tests down to INC IX. No additional failures yet, though I've yet to reach conditional CALL. 2017-06-19 20:04:55 -04:00
Thomas Harte
23177df26a Added various tests of the basic ALU ops. 2017-06-19 19:53:26 -04:00
Thomas Harte
ba15371948 Introduced timing tests for LDI[R] and CPI[R], fixing a latent issue in the rejig of LD BC, nn while I'm here. 2017-06-19 19:47:00 -04:00
Thomas Harte
8d60734737 Added tests for EXX, EX (SP), HL and EX (SP), IX. The latter two currently being incorrect. 2017-06-19 19:17:54 -04:00
Thomas Harte
002098d496 The final two tests were at fault — expecting POPs to write rather than read. Fixed, so the subset of timing tests as-yet implemented now passes. Which means it's time to slog through further tests. 2017-06-19 07:45:41 -04:00
Thomas Harte
85c5c4405a Ensured that wait states don't appear unless requested (TODO: requesting), and made the output of my timing tests a little easier to parse. 2017-06-19 07:30:01 -04:00
Thomas Harte
d668879ba6 Started trying to wade back to passing tests. Working on the new timing tests first, and focussing on getting the Objective-C test machine to compile bus operations into machine cycles, which means indicating phase to all-RAM delegates. 2017-06-18 22:03:13 -04:00
Thomas Harte
e1a2580b2a Renamed BusOperation to MachineCycle::Operation. 2017-06-17 21:53:45 -04:00
Thomas Harte
b6f51474ff Ensured that -description can handle the newly-captured bus actions. 2017-06-17 18:20:30 -04:00
Thomas Harte
0f18768091 Disabled attempts at bus activity matching within the FUSE tests, at least until I settle on exactly what I intend to do. 2017-06-17 18:19:25 -04:00
Thomas Harte
50cd617bd9 Ensured test raises only the intentional failure exceptions. 2017-06-15 22:33:46 -04:00
Thomas Harte
838b818cd3 Finished transcribing first page of machine cycle documentation; several failures contained. 2017-06-15 22:19:49 -04:00
Thomas Harte
cf795562bf Continued filling in tests, fleshing out what the test machine captures as a result. 2017-06-15 20:59:59 -04:00
Thomas Harte
ac37424878 Set up a test class to allow me to discover which of the machine cycle sequences I'm in error on. 2017-06-15 19:06:59 -04:00
Thomas Harte
aed2827e7b Implemented a rudimentary way to test that instructions take as long as the FUSE tests think they should. Hence discovered that the (HL)-accessing BIT, RES and SET weren't. Corrected. 2017-06-12 22:22:00 -04:00
Thomas Harte
a48616a138 Fixed reference to Swift-world MachineDocument for the ZX81 file type. 2017-06-12 18:51:11 -04:00
Thomas Harte
8222aac9e3 Added an official declaration of support for ZX81 files. 2017-06-11 21:40:41 -04:00
Thomas Harte
77aa3c187e Rebranded ZX80O as ZX80O81P, with an eye to making it accept ZX81 .p files. Adjusted the initial selection part of the static analyser appropriately. 2017-06-11 21:38:32 -04:00
Thomas Harte
8116f85479 Allowed the static analyser to specify a ZX80 or 81, and a memory model. Neither is respected yet in the machine. 2017-06-11 19:12:20 -04:00
Thomas Harte
50be3a24fe Sought to ensure that Mode 1 interrupts aren't happening early. Which they seem not to be. 2017-06-11 13:30:08 -04:00
Thomas Harte
7e10c7f9d8 Relocated the ZX80/81 concept of a 'file' out from Tape into Data, given that it's an exact duplicate of memory. 2017-06-08 19:09:51 -04:00
Thomas Harte
60300851ea Started sketching out a tape parser for ZX80 and '81 files. I think this'll help me to verify whether the .O input is working. 2017-06-07 10:12:13 -04:00
Thomas Harte
8c66e1d99d Factored out ZX80/81 video and rejigged to ensure it will keep ticking over irrespective of whether the machine is supplying data. 2017-06-06 17:53:23 -04:00
Thomas Harte
cc4cb45e9d Implemented keyboard input and ensured that the signal generated is marked as composite, putting the colour-suppression ball into the CRT's court. 2017-06-06 09:25:18 -04:00
Thomas Harte
c485c460f7 Imported the ZX80 and 81 system ROMs (though not publicly), added enough code to post their contents into C++ world. 2017-06-04 18:08:35 -04:00
Thomas Harte
b0a7c58287 Fixed project to point to the XIB I actually want to keep; fixed that XIB to have the correct contents. 2017-06-04 17:57:37 -04:00
Thomas Harte
d2637123c4 Added necessary support to get as far as an empty window when attempting to load a piece of ZX80 software. 2017-06-04 17:55:19 -04:00
Thomas Harte
02b7c3d1b0 Added the necessary wiring to get into a ZX80/81-oriented part of the static analyser, which could in principle post a ZX80 target. 2017-06-04 17:04:06 -04:00
Thomas Harte
8c1769f157 Made a quick attempt at serialising from ZX80 .O to waves. 2017-06-04 16:59:26 -04:00
Thomas Harte
655809517c Ensured that there is a subclass of file that is entrusted to load .O/.80 files, and that the code routes such files to it, noting that it should consider whether a ZX80 is required. 2017-06-04 16:37:03 -04:00
Thomas Harte
2190f60a89 Reinstated manual-by-stealth secondary usage of the Zexall test as a benchmarking tool. 2017-06-04 15:46:35 -04:00
Thomas Harte
0eebfdb4cc Expanded emulation of memptr, though still incomplete. Reverted zexall tests to zexdoc. Will probably leave memptr until I've an emulated machine as test suites seem to exist, but they're machine-dependant, so figuring out how to isolate them from an architecture will be a lot easier if and when I have functioning machines. 2017-06-04 15:39:37 -04:00
Thomas Harte
7811374b0f Started sneaking in memptr emulation, hopefully to get to a working BIT (hl). 2017-06-04 15:07:07 -04:00
Thomas Harte
87095b0578 Undid consciously discard for bits 3 and 5 in the FUSE tests. Back to 100 failures. 2017-06-04 14:04:26 -04:00
Thomas Harte
b642d9f712 Eliminates the 6502's specialised jam handler in favour of the generic trap handler, and simplifies the lookup costs of that as it's otherwise doubling execution costs. 2017-06-03 21:54:42 -04:00
Thomas Harte
fd6623b5a5 Attempted to bring a common hierarchy to the Z80 and 6502 test machines, particularly with a view to eliminating the special-case Jam stuff on the 6502. 2017-06-03 21:22:16 -04:00
Thomas Harte
b304c3a4b9 Eliminated the 6502's reliance on the micro-op scheduler. 2017-06-03 20:30:07 -04:00
Thomas Harte
b3da16911f Tweaked timing of mode 0, per contradictory information. Wrote a failing test of mode 2. 2017-06-03 18:42:54 -04:00
Thomas Harte
e52892f75b Added a test of interrupt mode 1. 2017-06-03 18:16:13 -04:00
Thomas Harte
8c41a0f0ed Added a test to confirm interrupts are disabled, and a response to the interrupt cycle within the all-RAM machine. 2017-06-03 17:53:44 -04:00
Thomas Harte
3e9212aaff Plumbed through to allow interrupt tests, wrote an NMI test, corrected the error revealed. 2017-06-03 17:41:45 -04:00
Thomas Harte
d14902700a Minor syntax and wiring fixes. 2017-06-01 22:33:05 -04:00
Thomas Harte
c95c32a9fe Implemented the reset line program and disabled fictitious automatic power-on reset for the Z80 test machine. 2017-06-01 22:31:04 -04:00
Thomas Harte
494ce073b5 Tests having been fixed by instating proper Z80 cycle counting, removed caveman logging. 2017-05-31 19:58:57 -04:00
Thomas Harte
5ff73faf48 Ensured Zexall can pass. 2017-05-31 19:55:06 -04:00
Thomas Harte
2f7f11e2e5 Added diagnosis props. 2017-05-31 06:54:25 -04:00
Thomas Harte
5119997122 Made an attempt, flawed so far, to find a neat way for processor subclasses to offer bus management as an inline function. 2017-05-30 22:41:23 -04:00
Thomas Harte
7bddd294c9 Resolved an unpredictable conditional and temporarily disabled the Zexalltest as part of the default suite, since it takes so long to run. 2017-05-30 21:03:02 -04:00
Thomas Harte
244b5ba3c2 Added a proper termination condition for Zexall and, for now, a Mhz counter. 2017-05-30 18:32:38 -04:00
Thomas Harte
960de7bd7b Marginally reduced test machine costs based on usage. 2017-05-30 11:59:07 -04:00
Thomas Harte
c6185baa99 Fixed R incrementation and attempted to make the status flags cheaper to write to. 2017-05-29 22:23:19 -04:00
Thomas Harte
4d4695032c Discovered that Zexall is just really slow. Disabled the address sanitiser, and started working towards a verifiable end. 2017-05-29 21:46:00 -04:00
Thomas Harte
6d22f6fcd5 Having decided the bus operation error on 10 is probably in the test cases, decided to allow myself to skip that one comparison. Back to zero failing cases, and with no more useful information to derive from the FUSE test set for the time being. 2017-05-29 17:17:17 -04:00
Thomas Harte
8bfaa487ce Improved logging of bus operations and corrected placement of the OUT step in that repetition group; was otherwise outputting the wrong side of the B adjustment and therefore to the wrong port (if interpreted as 16 bit). 2017-05-29 17:13:24 -04:00
Thomas Harte
267b2add9a Adjusted for where FUSE nominally places timestamps. Down to 92 failures. 2017-05-29 16:44:07 -04:00
Thomas Harte
d290e3d99e Corrected simple logging error. Which mysteriously moves me all the way up to 117 failures (!) 2017-05-29 16:35:00 -04:00
Thomas Harte
a6a4c5a936 Made an attempt to introduce checking of bus activity against the FUSE tests. Appears to suggest 54 new failures. 2017-05-29 15:57:27 -04:00
Thomas Harte
ed7b07c8b1 Made an attempt to implement HALT as an operation that merely leaves the PC in place, adding the Z80's output line. Included that flag in FUSE tests. Discovered that it does not think that HALT acts that way. Which is probably correct. 2017-05-29 11:54:27 -04:00
Thomas Harte
d83dd17738 [DD/FD]36 turns out to be a timing error: offset calculation overlaps with value fetch. So the FUSE test was cutting off my implementation early. Fixed. 2017-05-29 11:40:56 -04:00
Thomas Harte
9ade0dcae3 One failure was just PUSH AF due to throwing away the 5 & 3 flags at the start. Switched to throwing them away at comparison. 2017-05-29 11:06:23 -04:00
Thomas Harte
a329d85697 Instituted memory value checks, flushing out seven new failures. 2017-05-29 11:01:45 -04:00
Thomas Harte
c322410783 Corrected CP[I/D]R termination logic; all tests now passing to the extent of interrogation. 2017-05-29 10:52:54 -04:00
Thomas Harte
b67331e018 Fixing the OUT repetition group reduces the code to one failing test. 2017-05-29 10:48:53 -04:00
Thomas Harte
ad56a9215c Implemented IN[I/D]x. 18 failures remaining. 2017-05-29 10:12:33 -04:00
Thomas Harte

Thomas Harte
409c82ce73 Implemented RLD and RRD. 34 failures remaining. 2017-05-28 16:46:27 -04:00
Thomas Harte
6e83b7d6df Attempted to add a proper exit condition for Zexall. 2017-05-28 15:13:47 -04:00
Thomas Harte
5a4d448cc1 Corrected logical flags; now down to 68 failures, all of them on the ED page. 2017-05-28 15:09:58 -04:00
Thomas Harte
6b66c8f304 Implemented inputs and outputs, determined how to answer port requests to please FUSE and hence reduced failures to 84. 2017-05-28 14:50:51 -04:00
Thomas Harte
035df316aa FUSE seems to have inconsistent ideas about where b3 and b5 come from in more-complicated BIT instructions. So I'm not testing them for now. Within that reality, reduced to 102 failures. 2017-05-27 23:54:53 -04:00
Thomas Harte
c7cb47a1d8 Readded and then disabled my temporary one-test-only patch. Failures are currently at 237. 2017-05-27 21:10:25 -04:00
Thomas Harte
98423c6e41 Accepted FUSE's view of bits 3 & 5 from BIT and RES, reducing to 623 issues. 2017-05-27 16:19:15 -04:00
Thomas Harte
33c3fa21e3 Fixed (HL)/(In + d) CB page modify instructions. Reducing failures to 672. 2017-05-27 15:54:24 -04:00
Thomas Harte
9bc2b48d9b Found a form I like for indexed addressing, applying it only where obvious for now. Which eliminates more than a couple of hundred of remaining failures. 2017-05-26 23:23:33 -04:00
Thomas Harte
e4e71a1e5f Switched back to descriptive failures, but put a cap on them. 2017-05-25 21:08:24 -04:00
Thomas Harte
fba5af280e Shortened failure message, at least for now. 2017-05-25 21:05:47 -04:00
Thomas Harte
2cadc706e2 Now runs FUSE tests, albeit testing only a subset of the results. But enough to get started. 2017-05-25 21:00:33 -04:00
Thomas Harte
3c6f63abcc Started towards running the FUSE tests. Just need to deal with the memory segments. 2017-05-25 19:12:59 -04:00
Thomas Harte
00cd7e7e9c After hitting my head against the wall of trying to use [NS]Scanner as a parser some more, have given up and transcoded the two tests files to JSON. 2017-05-25 18:20:13 -04:00
Thomas Harte
055c860b43 Sealed off RegisterState as immutable, and started trying to parse the .expected file. 2017-05-23 22:32:36 -04:00
Thomas Harte
454c8628c3 Implemented an additional constructor for RegisterStates, pulling it out into file-level scope and implementing Equatable. 2017-05-23 22:05:33 -04:00
Thomas Harte
a23a6db4d6 Tidied up, creating a holder for RegisterState and giving it deserialisation logic. This makes sense because a register state will also need to be taken from the outputScanner, and from the machine. 2017-05-23 08:13:24 -04:00
Thomas Harte
6575091a78 Fixed Z80's ownership of its fetch-decode-execute program, its habit of scheduling invalidly when hitting an unrecognised operation and the test machine's habit of dereferencing invalidly. 2017-05-22 21:50:34 -04:00
Thomas Harte
9e25d014d2 Made an attempt to log bus activity for comparison with FUSE results. 2017-05-22 19:49:38 -04:00
Thomas Harte
41d5dd8679 Added a memory access delegate to the Z80 all-ram processor, to allow access patterns to be captured. 2017-05-22 19:24:11 -04:00
Thomas Harte
22afa509ca Got to a parsing and towards an attempt to run FUSE tests. 2017-05-22 19:14:46 -04:00
Thomas Harte
3fb3cc8269 Got explicit about encodings. 2017-05-21 22:53:06 -04:00
Thomas Harte
e3e461d7cb Added a test class for running the FUSE tests. With nothing much in it. 2017-05-21 22:49:24 -04:00
Thomas Harte
c16fccb317 Fixed file names. 2017-05-21 22:43:07 -04:00
Thomas Harte
b9cffdf2bd Imported the FUSE tests. 2017-05-21 22:42:20 -04:00
Thomas Harte
01a064dd63 Added an empty ED page. 2017-05-20 17:29:30 -04:00
Thomas Harte
d910405648 Added enough infrastructure to be able to react to the two CP/M calls this cares about. 2017-05-19 21:53:39 -04:00
Thomas Harte
62b432c046 Added the concept of a trap handler to the all-RAM processor and exposed it via the test Z80 classes. 2017-05-19 21:20:28 -04:00
Thomas Harte
11d05fb3b8 Expanded a little on operations, added an implementation or two. 2017-05-19 19:18:35 -04:00
Thomas Harte
58efca835f Sought to add a further opcode. 2017-05-18 22:53:43 -04:00
Thomas Harte
da6e520b91 Merge branch 'master' into Z80 2017-05-18 22:30:51 -04:00
Thomas Harte
9398b6c2c8 Unable to differentiate, decided to map a Mac shift key to both Oric shifts. 2017-05-18 22:25:59 -04:00
Thomas Harte
a3dafa9056 Abbreviated uses of enumerations. 2017-05-17 21:44:08 -04:00
Thomas Harte
64d6ee1be5 Adjusted slightly to adapt to latest Swift warnings. 2017-05-17 07:49:48 -04:00
Thomas Harte
1378ab7278 Ensured initial program counter and stack pointer are correct for Zexall, fixed the Z80 to use a compile-time polymorphic call for bus access. 2017-05-17 07:36:06 -04:00
Thomas Harte
87a021ec2d Made further attempt to get as fas as having the Z80 attempt to do something. 2017-05-16 22:19:40 -04:00
Thomas Harte
189317b80c Added enough of a Z80 test machine to bridge up into Swift. 2017-05-16 22:05:42 -04:00
Thomas Harte
4f0775cc7c Imported the Zexall.com tester, as a first thing to throw at the Z80 to be. 2017-05-16 21:37:09 -04:00
Thomas Harte
7190f927b7 Factored out the stuff that both all-RAM processors would share, rather than duplicating it. 2017-05-16 21:28:17 -04:00
Thomas Harte
d559d8b901 Continued edging towards getting the absolute basics of a testable Z80, for test-driven development. Corrected old-fashioned instance naming issues with the corresponding 6502 class and removed an unnecessary source file while at it. 2017-05-16 21:19:17 -04:00
Thomas Harte
df80c37adb Renamed TestMachine to TestMachine6502 since there's going to be multiple of them. 2017-05-15 08:18:57 -04:00
Thomas Harte
0808e9b6fb Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair. 2017-05-14 22:08:15 -04:00
Thomas Harte
b81a2cc273 First tentative steps towards adding a Z80 implementation. 2017-05-14 17:46:41 -04:00
Thomas Harte
