Abstract

A computation engine (V8) based on eight VLSI vector signal processors (ZSP-322) was developed for dedicated DSP (digital signal processing) applications in areas such as nonparametric spectral estimation, beamforming, Doppler, etc. A design methodology and a set of tools were implemented and tested, facilitating multiprocessor algorithm development and hardware implementation. A novel scheme for assessment of the noise model of a complete system is reported. Multi-V8 implementation schemes for enhanced performance, such as pipelining, computation wave, and interleaving, are discussed and mapped to a quantitative performance space. The internal details of the ZSP-322 device are provided
