64 bit input, 128 bit output, 7 bit partitions into 8x8 input and 8x16
> How many cycles does it take to complete in best and worst case?
all parameteriseable so it's a non-question.
stages are combinatorial and the pipeline API can be used to construct
arbitrary chains with arbitrary register stages.
if any given setup is inadequate to meet timing we adjust 2 parameters and
the problem goes away.
