A cascadable multimode VLSI signal processor
B. Barazesh, Leena Mary · 2005
The purpose of this paper is to present the PSI, a fast 16/32 bit VLSI microcomputer for digital signal processing. The PSI proposes innovative architectural solutions to fit the high throughput requirements of complex algorithms. The multimode internal architecture matches the inherent parallelism of the algorithms and the external architecture allows to wire directly several processors together with external peripheral and memory chips. This multiprocessor architecture behaves as a data flow machine. A few examples of the kernel algorithms are presented and system architectures based on the PSI are described in some detail.
