Separates Z80Base.cpp into its component classes.

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

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

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.

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.

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

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.

Abstracts the target platform type out from the static analyser's ownership.

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

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.

Attempted to implement Sleeper in Drive and therefore in DiskController. Also corrected a couple of nonconformant file names.

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
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

Performed the normative removal from public view of Vic-20 implementation details. Which were hefty.

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

Made an initial attempt at typer support for the CPC.

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.

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

Added an empty husk to begin support for Amstrad CPC disk image formats.

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

Significantly increased quantity of keys forwarded.

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

Disabled the address sanitiser as an every-time run again, as it just pushes my computer a bit too far.

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.

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

Added to the static analyser the most basic through-path for Amstrad CPC content.
2017-07-30 21:15:20 -04:00
Thomas Harte

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.

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

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

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.

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!

Transcribed missing tests as TODOs.

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.

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
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

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.

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

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
