[Dspforum] Lab 6 Questions

[Doug Wenstrand]

Yea, I forgot to time it and fill in the requirement.  Your presumption of
course is correct -- We want you to use QDMA to do it efficiently, but you
need not worry about overlapping the transfers with computations.
So -- the following pseudocode is what would meet the timing requirement:

loop:
dma data in
wait for it
fft
dma data out
