What is this hybrid FPGA you're talking about?
Video processing, step by step:
1. Create algorithms in some tool (maybe C, Matlab etc).
2. Re-Architect algorithm for efficient implementation in FPGA, usually bit true.
3. Compare model in (2) to model in (1).
4. Repeat steps (2) and (3) until you have acceptable margin of error, or output is within tollerance.
5. Create HDL, based on model in (2).
6. Compare HDL to model from step (2).
7. Repeat steps (5) and (6) until you get a match.
8. Integrate into FPGA
9. Compare results from hardware to (5) and (2).
10. Go back to step (5) if there is no match.
