Thomas Harte
0418f51ef2 Takes a shot at emulation-mode 'exceptions'. 
It's just RTI and correct decimal SBC left of the official 6502s now, I think.
 2020-10-08 17:52:13 -04:00
Thomas Harte
b578240993 Adds a further error. 
Clearly I've severely overloaded 'JMP' and not fully thought through where it gets its addresses from.

Thomas Harte
703065a0a5 Takes a run at timer-linked PB7 output behaviour. 
Seemingly sufficiently to pass the VICE test (which I've transcribed), though with some guesswork.
 2020-09-20 14:51:59 -04:00

Thomas Harte
d7972a7b86 Enforces across-the-board supersampling. 
I'm damned if I can figure out how to talk an MTKView, or Metal in general, into supersampling so as a first effort this does it in software.
 2020-09-13 19:30:26 -04:00
Thomas Harte
bcaceff378 Simplifies in-Metal transform logic, loading responsibility for setup onto the CPU. 
I think I've also finally excised whatever order-of-operations issue I was having with regard to non-4:3 displays.
 2020-09-10 20:32:58 -04:00
Thomas Harte
d7b405c6f8 Ensures direct luminance -> 'RGB' video doesn't go down the composition pipeline. 2020-09-10 13:20:40 -04:00
Thomas Harte
edf8cf4dc6 Completes the set of with/without gamma, and ensures correct alpha selection. 
Also culls some other repetitive TODOs.
 2020-09-09 19:28:38 -04:00
Thomas Harte
dfcc8e9822 Switches some of the interpolated fields to half precision. 2020-09-09 18:17:05 -04:00
Thomas Harte
016e96e6f8 Extends usage of half. Possibly towards its conclusion. 2020-09-09 15:10:19 -04:00
Thomas Harte
e7ce03c418 Attempts to ensure initial finalised line texture state. 
This was an attempt to remove the vertical line on the left of a composite display. Obviously the cause is not as suspected.
 2020-09-09 13:15:21 -04:00
Thomas Harte
3d392dd81d Completes conversion of composite & S-Video per-pixel processing to 16-bit floats. 2020-09-09 13:02:04 -04:00

Thomas Harte
06b7ea5a6e Strips the luma kernel back to 1d. 2020-09-08 19:15:19 -04:00
Thomas Harte
c49fcb9ec9 Based on further play: one box filter to separate luma/chroma, another to filter chroma, plus a FIR sharpen on luma. 2020-09-08 16:35:05 -04:00
Thomas Harte
0e44d6d214 Experiments with an all-box filter. 2020-09-08 16:19:08 -04:00

Thomas Harte
55e576cc57 Ensures unpainted areas in composite displays have a non-asymptotic effect on luminance calculations. 2020-09-03 21:10:30 -04:00
Thomas Harte
6bd8ec9545 Alas, 1.0 seems to be the limit for proper artefact colour. 2020-09-03 20:53:45 -04:00
Thomas Harte
5cd8d86eef Switches to dynamic generation of the 'sharpness' filter, correcting issues with the Apple II (amongst others). 2020-09-03 20:48:44 -04:00
Thomas Harte
74d0acdaec Fixes non-RGB colour composite generation. 
The hard-coded sharpen filter proves to be a really bad fit for the Apple II though.
 2020-09-03 19:04:17 -04:00
Thomas Harte
0288a1974b Tries: separate filters for chroma and luma, plus a post-separation sharpen filter on the latter. 2020-09-03 13:18:21 -04:00
Thomas Harte
6efd8782fe Tweaks coefficients some more; makes sure that data is never larger than the intermediate buffers. 2020-09-02 20:14:41 -04:00
Thomas Harte
8bab9d5d60 Corrects S-Video and composite generation for RGB[1/2/4] sources. 
Also toys with a double luminance filter in order to try to sharpen chrominance. But maybe I should be looking at other convolutions entirely?
 2020-09-02 19:13:54 -04:00
Thomas Harte
7e58648743 Corrects front-running bug, plays further with colour amplitude. 2020-09-02 15:51:48 -04:00
Thomas Harte
0f0c3e616d Tweaks some numbers. 
I'm largely treading water here. Probably time to think about the race.
 2020-09-02 08:17:01 -04:00
Thomas Harte
c7ce65ea4c Attempts fully to restore composite video. 
Subject to some sort of nasty race condition for the time being.
 2020-09-02 08:03:10 -04:00
Thomas Harte
c36247b609 Ensures reuse of offset buffers. 
There seems to be some sort of epic race condition as the drawing pipeline lags though. Will need to investigate.
 2020-09-01 22:11:48 -04:00
Thomas Harte
15296e43a4 Attempts correctly to set up the CPU side of a composite video pipeline, at least. 
So: I think this is really close, but I'm out of time for the day.
 2020-09-01 21:58:33 -04:00

Thomas Harte
67ca298a72 Forces a no-op compute shader into the S-Video pipeline. 
The intention is to restrict the area acted over, and to do the S-Video filtering in there. Then I'll just need two such stages for composite.
 2020-09-01 18:39:52 -04:00
Thomas Harte
67d4dbf91a Starts girding for a third pipeline. 2020-08-31 20:01:59 -04:00
Thomas Harte
b344269140 I think I accept the need for intermediate steps now. 
This allocates storage.
 2020-08-30 20:21:01 -04:00
Thomas Harte
bb547610f2 Adds commentary, shrinks some intermediate texture sizes. 2020-08-30 12:06:29 -04:00
Thomas Harte
1e1f007bb7 Possibly convinces myself that no-separation chroma/luma isn't practical. 
... as appealing as it may be, were filters perfect.
 2020-08-29 21:25:49 -04:00
Thomas Harte
c40d858f02 Switches back to angular stuff at input resolution; ensures all S-Video modes work. 
Now to roll back onto composite. Fingers crossed!
 2020-08-29 20:54:46 -04:00
Thomas Harte
3d564d85fd Proves that per-pixel sine/cos evaluation avoids phase issues. 
Even in PAL mode. But I'd rather not _require_ this as it kind of negates directly-sampled input.
 2020-08-29 18:53:37 -04:00
Thomas Harte
02cea40ffa Attempts to avoid introducing phase error in scanToComposition. 
Also brightens S-Video up to RGB levels.
 2020-08-25 22:41:37 -04:00
Thomas Harte
e502d336db Having decided that these things probably need to be separate, starts drilling down on S-Video. 2020-08-25 22:05:19 -04:00
Thomas Harte
807cb99f6d Composite angles are signed. 2020-08-23 21:39:04 -04:00
Thomas Harte
7ca0362f23 Treads water. 
Difficult current question: why does the Atari 2600's display change colours as the display tries to achieve horizontal lock? Phase should be unchanged. Ergo something is amiss.
 2020-08-23 21:03:26 -04:00

56c7bd242a Marginally tidies. 2020-08-22 16:38:36 -04:00
