This paper surveys nine designs for VLSI circuits that compute N-element Fourier transforms. The largest of the designs requires O(N2 log N) units of silicon area; it can start a new Fourier transform every O(log N) time units. The smallest designs have about 1/Nth of this throughput, but they require only 1/Nth as much area.
