[Libre-soc-dev] DCT/FFT augmentations

[Luke Kenneth Casson Leighton]

ngggh stress!

defining which dimensions shall be skipped, which paused, in order to
do a schedule for matrix multiply, is melting my brain.

for i
   for j
      for k
        result jk  X ik  Y ij

something like that, and i have to define "modes" for each of result, X, and Y.

remember that it is imperative that the sequential issue of FMACs
*not* sit on the same result, otherwise the execution engine will be
jammed with Read/Write hazards.
