Abstract

Anovel MIMD (Multiple Instruction Multiple Data) based architecture consisting of multiple processing elements (PE) has been developed. This architecture is adapted to real-time processing of sequences of different tasks for local image segments. Each PE contains an arithmetic processing unit (APU), adapted to parallel processing of low level operations, and a high level and control processor (HLCP) for medium and high level operations and control of the PE. This HLCP can be a standard signal processor or a RISC processor. Because of the local control of each PE by the HLCP and a SIMD structure of the APU, the overall system architecture is characterized as MIMD based with a local SIMD structure for low level processing. Due to an overlapped computation and communication the multiprocessor system achieves a linear speedup compared to a single processing element. Main parts of the PE have been realized as two ASICs in a 1.5 jim CMOS-Process. With a system clock rate of 25MHz, each PE provides a peak performance of 400 Mega operations per second (MOPS).
