f9a5595dad Added seeking tests, correcting such errors as uncovered. 2016-12-18 10:19:24 -05:00
Thomas Harte
3297f6d545 Made an attempt to implement seek_to on PCMSegmentEventSource, taking account of off-by-half counting. 2016-12-17 22:44:33 -05:00
Thomas Harte
3116a2cf4c 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
313db75303 Ensured the patchable track owns its underlying track. 2016-12-17 18:17:22 -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. 2016-12-17 17:05:49 -05:00
Thomas Harte
f1a08b7ab5 Opted to pass times by reference and added enough to PCMPatchedTrack that it could start being used by the disk controller, albeit that it doesn't work. 2016-12-17 16:26:45 -05:00

dc08a23ceb This is going to be a slow walk, I think. This class attempts to be the scratchpad which will hold in-memory track modifications. 2016-12-16 19:20:38 -05:00

ea1b3d447b Merge pull request #85 from TomHarte/ElectronRefactor
Applies a healthy cleaning to the Electron implementation
2016-12-15 19:53:07 -05:00

63107cd492 Tidied, very slightly. 2016-12-15 19:49:25 -05:00
Thomas Harte
a555c5762a Rearranged code, hopefully into a more logical grouping. 2016-12-15 19:47:04 -05:00
Thomas Harte
4a7ddaf2e9 Added documentation and a quick note to self. 2016-12-15 19:43:04 -05:00
Thomas Harte
f61176cd7d Reinstituted something of the don't-do-pixel-work-until-an-affecting-write-occurs optimisation. 2016-12-15 19:20:14 -05:00
Thomas Harte
c1c70a767a Attempted fully to reinstate proper timing. 2016-12-15 18:52:16 -05:00
Thomas Harte
0326316bb8 Reinstated whole-frame counting. Thereby to reinstate proper interrupts. 2016-12-15 18:09:49 -05:00
Thomas Harte
b58b11fc93 Switched to a table-based dispatch of line-by-line actions, primarily to simplify. 2016-12-15 18:07:46 -05:00
Thomas Harte
fd541e1142 An early draft; dealing with the issue that not all cycles are necessarily consumed in a single call. Incomplete; broken. Committing for cross-machine visibility. 2016-12-12 08:01:10 -05:00
Thomas Harte
be7e05e109 Started attempting to move total responsibility for display-related interrupts and RAM timing into the video. 2016-12-11 18:34:49 -05:00
Thomas Harte
c5cf8d9531 Ensured the video subsystem correctly handles requests to run over a frame boundary. 2016-12-11 16:17:51 -05:00
Thomas Harte
52028432e1 Restored some semblance of output. 2016-12-10 22:19:10 -05:00
Thomas Harte
0aae1bd1ef Fixed calculation of termination cycle. 2016-12-10 21:35:41 -05:00

c43e481a33 Started factoring video out of the Electron. 2016-12-10 21:07:52 -05:00

0653770c63 Merge pull request #84 from TomHarte/OricColour
Switches to using the original Oric colour ROM to generate Oric composite values
2016-12-10 19:37:17 -05:00
Thomas Harte
e62be03673 Removed endianness assumption. 2016-12-10 19:10:33 -05:00
Thomas Harte
34d213dec4 Decreased Y resolution, again also hopefully temporarily. 2016-12-10 15:35:38 -05:00
Thomas Harte
81a102d951 Upped intermediate buffer size, at least temporarily, while I look for the source of the interference patterns I'm seeing. 2016-12-10 15:20:10 -05:00
Thomas Harte
a5683dfb21 Removed now untrue comment. 2016-12-10 15:19:48 -05:00
Thomas Harte
0e71802b92 Reduced Oric video to single nibble constants. Removed attempt at asynchronous flush as no longer required. 2016-12-10 14:17:46 -05:00
Thomas Harte
580f347727 Fixed Oric SCART mode by having it change what it's giving to the CRT based on which shader it knows will be active. 2016-12-10 13:55:56 -05:00
Thomas Harte
a549fd1ecc Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron. 2016-12-10 13:42:34 -05:00
Thomas Harte
e359441e2f Added a readme.txt for the omitted Oric ROMs. 2016-12-09 22:18:11 -05:00
Thomas Harte
6cdd41e5a9 Added direct use of the colour ROM, uploading 16 bits per pixel to contain the entire ROM composite wave. 2016-12-09 22:17:10 -05:00
Thomas Harte
3b5962b171 This is an initial attempt at using the actual Oric colour ROM values for composite video generation. 2016-12-09 20:01:27 -05:00
Thomas Harte
c4041b06a8 This'll do as a write interface, won't it? 2016-12-07 22:19:20 -05:00

46ebae7e4b Merge pull request #83 from TomHarte/InterruptLine
Corrects interrupt line handling of the WD and Microdisc
2016-12-06 21:21:35 -05:00
Thomas Harte
c304db0f5a Deintegrated the busy flag and the interrupt request line, as the latter is reset by status reads. Which also means I can start reporting the WD INTRQ line status directly from the Microdisc. That appears to be correct, rather than honouring the Microdisc IRQ select there. 2016-12-06 21:16:29 -05:00
Thomas Harte
4d3bdf8c7c Fixed failure to initialise the Microdisc flag if loading a tape. 2016-12-06 20:29:05 -05:00

0300ae4ec0 Merge pull request #82 from TomHarte/VideoRacing
Pulls the texture builder into flush/submit orthodoxy
2016-12-06 19:13:05 -05:00
Thomas Harte
5216dda675 Added some brief extra exposition to the texture builder, cut all internal tex_x/y and source_divider stuff from the CRT. 2016-12-06 19:08:55 -05:00
Thomas Harte
33d52bb573 Ensured no over-moving. 2016-12-06 19:02:18 -05:00
Thomas Harte
4ff33254e1 Sought to shift locking back up to the CRT. And to be a bit more RAII-ish. 2016-12-06 18:48:30 -05:00
Thomas Harte
60f9ddfde8 Fixed start test and added incrementation of start locations. 2016-12-06 08:08:57 -05:00
Thomas Harte
f388ba11cc Missed an initialisation. Fixed! 2016-12-06 07:26:23 -05:00
Thomas Harte
0fee8096c1 Made an attempt to shuffle the texture builder to a similar flush/submit pattern as the input builder. Don't care about thread safety yet, as it's obvious I'm going to need to move that back up to the CRT. 2016-12-06 07:24:07 -05:00
Thomas Harte
0edc043378 Started introducing an extra layer of indirection so as to be able to bind the texture builder to the same flush and submit patern as the array builder. 2016-12-03 20:47:19 -05:00
Thomas Harte
cb3c837e30 Simplified interface by baking in last-minute-only updates. 2016-12-03 18:19:12 -05:00
Thomas Harte
ca50606e1d Restored Vic audio. 2016-12-03 17:10:47 -05:00

0220d33562 Resolved failure of initial state setting, which was causing tests sometimes to fail. 2016-12-03 16:42:10 -05:00
