Cool stuff!
What about using the same system generating GPU code (OpenGL/GLSL, OpenCL, Cuda, ...) for video DSP stuff?
I've been far removed from that world for a while. Last time I looked there was just OpenGL with some 8-bit texture ops.
What would be a good way to start? There seems to be several non-orthogonal ways to get access to 2D graphics these days.
What I want to do is to get the image processing part of PDP to run on the GPU. Target platforms: desktop, Android, iOS, something like raspberry pi, ... Currently probably Android as first attempt.
Also, PDP is 16 bit integer pixel depth. Is that something that can be done easily these days?
