38f944bc34 This needs to be a memmove as the areas may overlap. 2017-01-29 16:13:33 -05:00
Thomas Harte
427175b9c0 Added an extra flag to avoid potential race condition on is_full_, being reset from the background despite a write area not having been allocated. 2017-01-29 16:13:28 -05:00

2390358c24 Prevented unbounded CPU usage, albeit without yet deciding who has authority for the clock rate. 2017-01-29 14:19:26 -05:00

2432a3b4d7 Fixed condition — >= is smarter. 2017-01-29 14:00:01 -05:00

9c3597c7e3 Attempted to reintroduce enough logic to handle [most of] line timing, such that WSYNC works. Initial objective is to get back to having a working background. 2017-01-29 13:47:36 -05:00

fba6baaa9c Stubbed and disabled to get back to building. 2017-01-28 21:56:01 -05:00

a246530953 Supposing the TIA were implemented, this is (more or less) what the Atari 2600 would now look like. 2017-01-28 21:46:40 -05:00
Thomas Harte
0ffded72a6 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. 2017-01-28 16:19:08 -05:00

55fe0176bd Added a space. Probably need to hold for a better example though. 2017-01-12 22:12:37 -05:00

99fcbb55d1 Attempted to improve layout. 2017-01-12 22:11:25 -05:00

6f78ecd12b Added a small pictorial example. Hardly the best, but a step in the right direction. 2017-01-12 22:06:45 -05:00

ced644b103 It seems likely that an AY divides its clock by 8, not 16. I had conflated wave frequency and counter clock. 2017-01-11 22:03:01 -05:00
Thomas Harte
be1cb2a551 Fixed NTSC phase. 2017-01-11 21:31:24 -05:00
Thomas Harte
b4159295f6 Switched to using quads for intermediate draws. The specific concern is the flexibility offered in the GL spec as to line drawing algorithms. And even if a driver implements exactly to spec then it should omit the final pixel. 2017-01-11 21:18:41 -05:00
Thomas Harte
d0a93409e6 Made an attempt to simplify in-shader phase calculation, now that output position is a direct multiple of phase. 2017-01-11 08:18:00 -05:00
Thomas Harte
4c3669f210 Reduced precision of input phase, but I'm not necessarily persuaded by it as a move. However it's clear that something is off in that whole area. But if phase is locked by output position, do I need to retain this level of complexity? Also ensured that intermediate buffers prior to the final are sampled using the nearest sampling mode, also to reduce precision errors. 2017-01-10 22:08:07 -05:00
Thomas Harte
eeb646868b Switched off filtering, at least temporarily, to try to ensure that sampling is all where it should be. 2017-01-08 19:53:08 -05:00
Thomas Harte
3d789732a2 Switched back to full buffer clearing. Until I can figure out the source of noise. 2017-01-08 19:50:31 -05:00
Thomas Harte
d2a7d39749 Ensured the output lock isn't held while talking to the delegate. 2017-01-08 19:49:21 -05:00

9521718120 Colour phase is multiplied by 255, not 256. 2017-01-08 17:21:26 -05:00

28909e33ca Eliminated phaseCyclesPerTick as implied. 2017-01-08 16:48:02 -05:00

79632b1d34 Instituted de-escalating phase-related extensions, definitively to kill rounding error edges. 2017-01-08 16:24:22 -05:00
