A cascadeable pipeline Fast Fourier Transform switch with built-in self-test
A pipeline Fast Fourier Transform (FFT) switch with built-in self-test is described. The pipeline FFT, a one-dimensional systolic array, is composed of complex butterflies and FFT switches. The FFT switches are cascadeable and can support the implementation of a radix-2 pipeline FFT of up to 8192 points. The 10 000 gate ASIC device is fabricated in 1.5μm HCMOS gate array technology, and supports a throughput of 25 Mwords s-1.
