Description: This file contains the code for the implementation of FFT. The Algorithm
used is Decimation in Time. For the optimization point of view, the whole
computation of butterfly signal flow has beeen divided in three parts. The
first part, the middle part and the last part. In the first part, the
Stage 1 and Stage 2 of the butterfly structure are implemented. In the 2nd
part the general butterfly computation is done, which corresponds to the
middle stages of butterfly. In the last part the last stage of the buttrfly
structure is implemented, where mainly the loop overheads are saved.
