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
c56a5344b9 Implemented CP[I/D]x. 2017-05-29 08:54:00 -04:00
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
