Fast Fourier transform hardware implementations--An overview
G. D. Bergland · IEEE Transactions on Audio and Electroacoustics · 1969
This discussion served as an introduction to the Hardware Implementations Session of the IEEE Workshop on Fast Fourier Transform Processing. It introduces the problems associated with implementing the FFT algorithm in hardware and provides a frame of reference for characterizing specific implementations. Many of the design options applicable to an FFT processor are described, and a brief comparison of several machine organizations is given.
