That's quite an extensive tour through the world of image signal processing.
I can't quite grok the filter added to the DDS to generate twiddle factors for FFTs. I'll have to re-read that section a few time for it to sink in.

FPGAs? This is something I assumed was processed long ago with ASICs

But asics are a big $$$ ask.

what do you mean? in image processing or in general? in general they're used a lot where performance is important, especially in high frequency trading, crypto-mining, etc. also they're quite important for image processing in defence/medical imaging.
