A chip set for pipeline and parallel pipeline FFT architectures
Journal of VLSI Signal Processing , Volume 8 - Issue 3 p. 253- 265
A chip set for pipelined and parallel pipelined FFT applications is presented. The set consists of two cascadeable chips with built-in self-test and a chip-interconnectivity test feature. The two ASICs are a 15k gate Complex-Butterfly and a 9k gate FFT Switch. The Complex-Butterfly uses redundant binary arithmetic (RBA), a modified Booth algorithm and a Wallace tree architecture to achieve a throughput of better than 25 Msamples/sec. The cascadeable FFT Switch is designed to support the implementation of radix-2, 2N point, pipeline FFTs. Both devices have been fabricated in 1.5 μm CMOS gate array technology.
