VLSI fast Fourier transform digital signal processor chip
Abstract
A high performance VLSI chip has been designed to perform the Fast Fourier Transform (FFT) used in digital signal processing systems. This Bendix proprietary, custom digital signal processor (DSP) chip performs a 128 Point FFT and has a wide range of avionics and aerospace applications ranging from radar to sonar systems. The chip employs a novel algorithm designed to efficiently implement the FFT with a minimum of hardware by eliminating all multiply operations while achieving high throughput rates. It executes both the Fast Fourier Transform and the Inverse Fast Fourier Transform which are powerful tools in frequency domain analysis.
