WebNov 1, 2015 · The radix-2 FFT developed in [3] has directly implemented the SFG for 16 and 32 points. As a result, a large number of butterfly units is required and hence, a relatively larger number of on-chip ... WebIn most FFT algorithms, restrictions may apply. For example, a radix-2 FFT restricts the number of samples in the sequence to a power of two. In addition, some FFT algorithms require the input or output to be re-ordered. For example, the radix-2 decimation-in-frequency algorithm requires the output to be bit-reversed. It is up to implementers ...
