The ideal is an bare bones equivalent of an OpenGL pixel shader, ie. - A function is executed for every output pixel. - This function has a sampler available to bring in arbitrary pixels from sources - This function can do some basic RGB maths (and, props for getting this far!) Toby tbz::spk /

Hi - I have nosed around the Milkymist SoC code. I can't claim to have grasped it all yet. There's some very impressive "technology" in there! I found one small bug, where the test bench for pfpu looks like it hasn't been kept up to date with pipeline length changes. Patch attached, relative t
