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.

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.

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.

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.

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

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
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.
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
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

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

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
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

Removed implementation file; this is only ever going to be a template.
2017-08-01 16:00:17 -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
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.

Merge branch 'master' into Memptr
2017-07-25 23:01:34 -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
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
660f0e4c40
Added Objective-C through wiring and a Swift test class for Memptr modifications. So far with a single test, that fails.

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

Rebranded ZX80O as ZX80O81P, with an eye to making it accept ZX81 .p files. Adjusted the initial selection part of the static analyser appropriately.

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.

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.

2017-06-04 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
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

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.

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

Renamed TestMachine to TestMachine6502 since there's going to be multiple of them.

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.

Created a placeholder class for a factored-out TIA. There's a bit more it'll need to do, like vending (or receiving) a CRT but this is the full hardware stuff, I think.

Thomas Harte
e081f224b6
Implemented a very basic PCMTrack test, nevertheless revealing an oversight in PCMSegmentEventSource related to improperly counting to the index hole if the final bit is set. Took that as a message that I should comment and document the event source.
2016-12-18 22:53:24 -05:00

Realised I was actually testing PCMSegmentEventSource, not PCMSegment; implemented a spread of tests; hence fixed PCMSegmentEventSource.
2016-12-17 21:47:13 -05:00
Thomas Harte
254cc41fd6
Made an attempt to separate and isolate the stuff of creating flux events from a PCMSegment, eventually to factor that out of PCMTrack and make it available also to PCMPatchedTrack.
2016-12-17 21:13:57 -05:00
Thomas Harte
3017062e89
Maybe TDD is the way to get over my activity block on this thing? Fixed the existing ArrayBuilder tests so that the tests target builds again, added an extremely trivial PCMTrack test, heading towards PCMPatchedTrack tests.

Even better: why include the 'Input' prefix when there's only one?
2016-11-16 22:57:17 +08:00
Thomas Harte
4d0d5eb919
Renamed the 'input buffer builder' to the 'input texture builder' to be explicit about what sort of buffer, and killed the prefix since it's namespaced. Also switched to std::vector.
2016-11-16 12:31:32 +08:00

Made an attempt to consolidate what I learnt of Oric encoding while building this hastily and untidily directly into the Oric implementation.

Thomas Harte
353c1c8ea3
Shifted ownership of PETSCII -> string conversion down to the storage layer, where it's useful for tape parsing.
2016-11-06 18:43:51 -05:00
Thomas Harte
1b15bc3a6c
Started relocating the tape parsers down from static analyser to storage, to signify that they may be used by the emulation (if fast loading is supported on that machine).

Thomas Harte
4a062c616f
Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation.
2016-10-11 22:20:13 -04:00
Thomas Harte

It's a bit of a mess but this is probably close to appropriate for Oric TAP files.

Not having read the C++ synchronisation primitives before, this async task queue is probably incorrect. But nevertheless, let's have a quick go at employing it — in a hideously thread unsafe fashion — for audio generation. What can possibly go wrong?
2016-10-07 16:56:34 -04:00

Installed hoglet's BCDTest as a formal part of the test suite; removed some redundant semicolons in the Wolfgang Lorenz tests while I was here.

By removing its status as a special case, eliminated the Atari 2600 document. It's fairly clear that my date with doing joysticks properly can be deferred only so much longer but this is no worse than previously things were.
2016-10-03 08:01:04 -04:00

Migrated the Vic document to a mere options panel.
2016-10-03 07:42:05 -04:00
Thomas Harte
f28881ec6b
... and with the return of stored options and the shift of the aspect ratio to somewhere else (to sit, temporarily), the Electron document is the first of the gang to die.
2016-10-02 22:04:47 -04:00
Thomas Harte
19457621d8
Redistributed ownership of the user defaults key prefix, the Electron now works other than that settings aren't retained.
2016-10-02 21:56:50 -04:00
Thomas Harte
f1b99263e0
Relocated responsibility for loading ROMs, giving an Electron that 'works' (i.e. options aside) again.
2016-10-02 20:39:06 -04:00
Thomas Harte
0c75c2fc41
Disabled all machine-specific document code, to force the migration of functionality. The 2600 works other than the little matter of input.
2016-10-02 16:57:57 -04:00
Thomas Harte
6c6e9830dd
Started factoring the options panels out, in the hope that they'll become the only machine-specific thing. At least in the short term.
2016-10-02 16:31:50 -04:00
Thomas Harte
abf47efd40
Factored out Commodore is-a-ROM test, allowing it to be used from the Commodore analyser and thereby allowing ROMs to get as far as the machine again.

Thomas Harte

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.

Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller.
2016-09-25 20:05:56 -04:00
Thomas Harte

Made a first attempt at Acorn ADFS support plus the start of a suitable analyser.
2016-09-25 17:46:11 -04:00
Thomas Harte
cd5939501f
Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770?
2016-09-20 07:36:57 -04:00
Thomas Harte
0ce901bd48
Added necessary wiring to get as far as asking an arm of the analyser to check out an Acorn disk image.

Thomas Harte
91cd7e143b
Started on the SSD/DSD support. Realised I had ommitted multiple head support from my disk class. Fixed that.

Thomas Harte
180c3df2d4
Calling it 'number theory' probably isn't accurate but extracted the CRC stuff and started using it for [M]FM encoding.

The Commodore analyser now at least hands off to somebody else a chance to parse disks.

Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator.

Added a header parser for Commodore tapes. No time to grab file bodies now; time to go to work.
2016-09-06 08:49:32 -04:00
Thomas Harte
8b933182af
Added enough wiring (hopefully) that the Commodore tape's GetFiles should be called when appropriate.
2016-09-06 06:39:40 -04:00

Introduced an NSDocumentController subclass.

Thomas Harte
7bc2b6b161
Added the minor piece that will allow analysis results to be obtained from Objective-C, and exposed to Swift in sufficient detail for it to be able to pass on to the machine.

Edging ever onwards; killed forced attempt at uniformity in targets, sketched out the interface for a next-file-from call to Acorn tapes.
2016-08-29 21:10:38 -04:00
Thomas Harte
d1abfc040c
Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area.
2016-08-29 08:48:49 -04:00
Thomas Harte
d9f0065154
Sketched out just enough classes to get through the get-contents-into-memory step of static analysis.

Thomas Harte
24938326ac
ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.
2016-08-27 18:26:51 -04:00
Thomas Harte

Actually, this is less prescriptive.
2016-08-27 13:42:51 -04:00

This is probably how the static analyser interface will look?
2016-08-23 21:35:59 -04:00
Thomas Harte
38aec44d85
Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded?
2016-08-15 19:44:41 -04:00
Thomas Harte
58297f1baf
Performed the basic metadata and routing for opening D64 files. Realised that I wasn't actually necessarily catching exceptions properly for all file opens, and fixed.

Thomas Harte
e55db0cfe8
Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.
2016-07-29 05:19:01 -04:00
Thomas Harte

Had a second bash at the PLL. Probably I should read some of the literature.

Thomas Harte
0aa90b943b
Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower.

Thomas Harte
1e9eedc314
Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.

Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.

Thomas Harte
ce2f5515c0
Made some minor documentation improvements, killed 6522.cpp as the 6522 is going to be a template only, attempting to promote good inlining behaviour.
2016-06-19 18:11:37 -04:00
Thomas Harte

Established a general pattern for machines that can type things. Started working on the Vic typing itself.
2016-06-19 13:10:52 -04:00
Thomas Harte
06fb2ff1c7
Started endeavouring to sketch out the boilerplate for writing a 6522 test harness. Added a default implementation of synchronise to the 6522 too, since not everybody is going to want one.
2016-06-18 09:28:46 -04:00

Minor on-disk shuffle, to try to clarify ownership of responsibility.

Added class prefix.

Thomas Harte
6522530e1c
Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely.
2016-06-06 21:56:02 -04:00

The Vic now captures the ROMs sent to it and has just enough infrastructure to get to a black screen. Progress!
2016-06-05 10:51:07 -04:00
Thomas Harte
8052ce9223
System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine.
2016-06-05 08:53:05 -04:00
Thomas Harte
363e14a92f
Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository.
2016-06-05 08:33:01 -04:00

5c4f35e13f
Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.
2016-05-31 21:23:44 -04:00

41c09f8c3f
Renamed CSCathodeRayView to CSOpenGLView as it no longer has any CRT-related responsibilities. It just does the GL and manages a serial dispatch queue.

Certainly at least seriously considering a separate holder for the "compile a shader" logic. Otherwise taking steps back towards PAL/NTSC decoding.

Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.

Thomas Harte
3437781abd
Started sketching out an interface for sound generation. Which made me realise that the CRT in CRTDelegate was redundant, since C++ has namespaces.

Implemented keyboard input.

Thomas Harte
0db8938d27
Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least.
2016-01-06 23:14:36 -05:00
Thomas Harte
616dc0b57c
Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping.

Thomas Harte
ab45c1d530
Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell.

Thomas Harte
aa0714fe27
Started sketching out an Acorn Electron emulation, as it's a platform I'm familiar with and will force me to figure out PAL decoding. Factored out NTSC-specific parts of the display decoding logic and hence added RGB output mode.

Thomas Harte
bc805a90fe
Wired up joystick directions, at least, and fire button presses get as far as the C++. But there's some latching to figure out before they'll work.

Thomas Harte
d19f8ed507
Removed the implicit reset upon 6502 startup, adding a reset line. Hence all tests now pass again. Added an empty shell for timing tests, the all-RAM 6502 now counting bus cycles.

Thomas Harte
3c25ead1f3
Started working out some of my retain cycles and general failures to release. Switched .mm filename so that Xcode will stop getting confused when I try to switch between implementation and interface files.

Thomas Harte

Switched to idiomatic source name, ensured latest project name is in all appropriate header places, threw texture coordinates slightly into the shader mix.

The overall architecture of who has responsibility for what is now very askew but: the CRT now outputs a tightly packed short buffer, with the probable OpenGL destination in mind. So it's now all fixed arithmetic internally. CRTFrame is reduced to a plain C struct with the intention that the OpenGL view will take responsibility for it and stop doing the back-and-forth sprint on getting buffer data. The Atari 2600 now outputs explicit blanks rather than level blacks for its border, so that it's easier visually to debug the CRT in its form as far as it has currently progressed: to drawing lines where the cathode ray gun would run while outputting pixel. I note that I'm still not quite getting vertical sync right yet — I'm just accepting it anywhere in teh frame — but that should be an easy fix.

Incoming: a 'CRT' class, to receive information intended for a cathode ray tube. To decode sync, etc.

This now goes just far enough to create an instance of Atari2600::Machine and push a ROM to it. Next jobs are to get a basic CRT emulation wired up, outputting to the window.

Shuffled things and guessed at things until the Xcode project was happy being subservient to the project proper.
