Hello.
Here are my suggestions for improving the blitter.
01) Fixed point x and y src/dst increments
This will allow for scaling and possibly rotation on 16 bpp screen modes.
02) Parallel operations on multiple bitplanes.
Hitting memory 16 bits at a time isn't efficient. If the blitter has say 8 internal shift registers it can
operate on 8 planes at once. This can be useful for processing multiple pixels in chunky modes (
16 bpp, 32 bpp too)
03) dst = src where src != some value
This will allow transparent operations on true colour modes without a mask.
Combine with a blend mode to make things interesting. Nice for alpha blending etc
04) colour expansion
It would be useful to be able to take a palette + bitplane and generate a true colour raster.
This would allow font blitting to use less memory.
05) Tile engine. I'm dreaming here but it would be kinda cool. Combined with blending it would be
awesome for old school 2d games.
06) Better control of bus arbitration. It would be better if it was more dynamic than in the ST. Polling to get good performance isn't nice :)
Just my 2p :)

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
