Kuang-cheng Ting, Chuan-Lin Wu · AFIPS conference proceedings · 1984
A versatile special-purpose VLSI fast Fourier transform (FFT) processor is presented. It can process variant data sizes of FFT and cooperate with other identical FFT processors to accomplish cascade and parallel FFT processing schemes. The operations of the single processor FFT processing scheme, the multiprocessor cascade FFT processing scheme, and the multiprocessor parallel FFT processing scheme are described. The results of performance analysis show that the combination of adaptive architecture capability and VLSI technology can provide a practical solution for meeting the goal of advanced real-time FFT processing.
