Figure 7.92 Second PE assignment
The assignment of butterfly operations can be determined from the binary
representation of the row number. A butterfly operation in row r is assigned to the
PEp( r) where

7.11.3 Input and Output Process Assignment
The allocation and assignment of the input and output stages is trivial. One PE is
required for each process in the loops. Also, only one memory will be active at a
time.
