28e6517234 Switched away from tracking absolute time to tracking relative. 2016-04-06 20:46:00 -04:00
Thomas Harte
d4be4c4769 Of course, I want min. Not max. 2016-04-06 20:27:48 -04:00
Thomas Harte
fd1f6a7e1f Expanded on thinking. 2016-04-06 19:35:53 -04:00
Thomas Harte
e885438363 The penny has finally dropped that I can drive the CPU stuff in a manner completely decoupled from the GPU stuff. For much improved parallelisation. 2016-04-06 19:34:34 -04:00
Thomas Harte
5aa6da221f Shifted responsibility for byte shifts, probably to a more logical place. 2016-04-05 22:19:14 -04:00
Thomas Harte
2248769df9 Pulled a bunch of selection parts outside of the loops. Probably exhausting this angle of attack. 2016-04-05 22:17:44 -04:00
Thomas Harte
8f87973a96 Switched to table-based byte to output conversion. 2016-04-05 22:07:10 -04:00
Thomas Harte
e35456612a Simplified 40-column to pixel conversion. 2016-04-05 20:44:05 -04:00
Thomas Harte
6dbd20ffde Expanded interface to rgb_sample to eliminate its need to make assumptions about globals, used expanded interface to compact Electron data to two pixels per byte. 2016-04-05 20:32:55 -04:00
Thomas Harte
7838507a7a Simplified sound generation. 2016-04-04 22:22:19 -04:00
Thomas Harte
c0cd1ed89e Made an attempt to consolidate timestamp bases to a single vector and hence to lump all geometry into one or two calls, with no repetitive setting of a uniform. I'm not sure the result is correct yet. 2016-04-04 21:57:27 -04:00
Thomas Harte
4595741ab0 Made an attempt not to interrupt the display link queue too much when emulation is running slowly. 2016-04-04 20:22:33 -04:00
Thomas Harte
729fddea1c Switched to integer textures, likely to simplify for most use cases. 2016-04-04 19:39:01 -04:00
Thomas Harte
a6ef78862c This'll probably do for now. 2016-03-24 22:20:00 -04:00
Thomas Harte
f1caf62ff2 Continuing the switch around. 2016-03-24 19:31:41 -04:00
Thomas Harte
738186e323 Edging back towards shifting things to the stack. 2016-03-24 19:17:44 -04:00
Thomas Harte
3ca58b2a57 Attemted further to diminish jumpiness. 2016-03-22 22:07:30 -04:00
Thomas Harte
8cd5d40e00 Made an attempt to reduce the amount of data heading to the GPU. 2016-03-22 21:16:32 -04:00
Thomas Harte
3038704977 Attempted to introduce a lowpass filter to the graphics output, reverted 6502 optimisations as seemingly not working. 2016-03-21 22:01:25 -04:00
Thomas Harte
5db0f9e2d5 Shunted a few more things onto the stack. 2016-03-20 22:59:21 -04:00
Thomas Harte
9a82f028aa operation is now also stack local. 2016-03-20 22:52:49 -04:00
Thomas Harte
2f174b3a3e Moved operand to stack-local storage. 2016-03-20 22:50:16 -04:00
Thomas Harte
5966ac845f Switched symbols and updated all-RAM 6502 in order to fix unit test target. 2016-03-20 22:48:56 -04:00
Thomas Harte
197cf2a834 Commented out sync; it can probably be implicit. 2016-03-20 21:42:05 -04:00
Thomas Harte
902017a962 Fixes: drop any processing backlog, try not to allow an Electron document to close mid-draw, perform a frame grab even if the emulated machine is over-processing, really really don't create a CRT until it's safe. 2016-03-20 18:42:37 -04:00
Thomas Harte
fb6fb5d948 Switched to two-phase setup to deal with OpenGL scheduling. 2016-03-20 13:50:13 -04:00
Thomas Harte
eabc382540 Fixed: of course I can't rely on the pointer to CVTimeStamp not becoming dangling during a queue jump. 2016-03-19 23:02:42 -04:00
Thomas Harte
4c5d66c317 Made sure GL context isn't activated until it's locked. 2016-03-19 22:54:56 -04:00
Thomas Harte
a546277f88 Added the simplest mechanism to decouple emulation from the display link queue. 2016-03-19 22:53:37 -04:00
Thomas Harte
9da7716c72 Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow. 2016-03-19 22:46:17 -04:00
Thomas Harte
aa8a192c7e Simplified API down to their being a single texture with a specified depth. 2016-03-19 17:37:55 -04:00
Thomas Harte
4ac1f959e9 A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything. 2016-03-19 17:07:05 -04:00
Thomas Harte
5b37a651ac Made an attemp to deal with glUnmapBuffer(GL_ARRAY_BUFFER) == GL_FALSE. 2016-03-18 21:35:52 -04:00
Thomas Harte
0b1c9fb291 Ensured I don't interrupt triangle strips for the purpose of glDrawArrays. 2016-03-18 21:28:53 -04:00
Thomas Harte
620257e29e Switched to a client wait, as I try to figure out what's going on. 2016-03-18 21:21:35 -04:00
Thomas Harte
2e4af90e2d Resolved output errors. 2016-03-18 21:19:11 -04:00
Thomas Harte
10bc33464d I don't think this is quite correct, but it's better. 2016-03-18 21:14:06 -04:00
Thomas Harte
b074860031 Updated to latest information on interrupt timing. 2016-03-18 21:11:25 -04:00
Thomas Harte
61e880de03 Keeping a buffer permanently bound is apparently illegal. So back to copying in on demand. Which I think still improves on synchronisation, but not much. 2016-03-18 21:11:09 -04:00
Thomas Harte
c8ecfb89d8 Some cleaning. 2016-03-16 22:52:33 -04:00
Thomas Harte
0d27d3bb7f As messy as it is, this use glMapBufferRange to avoid explicit buffer submits. 2016-03-16 22:29:22 -04:00
Thomas Harte
ca35a7e222 Ensured that a much greater input rate than output is handled correctly. 2016-03-16 20:38:17 -04:00
Thomas Harte
4cd0aa3416 Completed FIR filter based audio output. 2016-03-15 23:37:35 -04:00
Thomas Harte
726c98446a Fixed a couple of memory leaks, at least got as far as instantiating a filter. 2016-03-15 21:34:00 -04:00
Thomas Harte
5b509e5360 Fixed: const should have been static constexpr; should probably use new and delete rather than malloc and new. 2016-03-15 21:33:18 -04:00
Thomas Harte
a4ec0b023c Made some type conversions explicit. 2016-03-15 21:25:02 -04:00
Thomas Harte
7694297c83 Introduced an adapted version of the previous Clock Signal's FIR filter. 2016-03-15 21:05:20 -04:00
Thomas Harte
0edf165401 Fixed sound pitch, though I'm not yet exactly sure why. 2016-03-14 22:52:16 -04:00
Thomas Harte
9a492ac15f Made a further guess at the state interrupts would probably be left; slightly simplified interface. 2016-03-14 22:42:52 -04:00
Thomas Harte
15120d8fb6 Switched to probably more accurate contended memory, resolved issue of not leaving the tape data received interrupt set when returning a byte from the fast tape, fixing Joe Blade, and tested slightly further to determine that interrupts probably signal upon entry into horizontal sync. 2016-03-14 19:29:28 -04:00
