High Speed Vision System Using Massively Parallel Processing

Abstract

Abstruct-A visual processing system for early vision using massively parallel processing is described. The system named SPE-4k (Sensory Processing Element - 4k) has 64x64~4096 processing elements (PE’s) which are directly connected with photo detectors in parallel. Eight PE’s are integrated into an originally developed LSI. An mesh type networks is used for interconnection among PE’s. The system carries out input and processing of visual information at extremely high speed by using massively parallel processing. Edge detection using four neighborhoods, for example, can be done in 3.3~s. Since the PE is designed to be so compact that the system can be integrated, the system is regarded as a scale up model of integrated parallel processing vision system in future. In this paper, architectures of the parallel processing LSI and the SPE-4k system are shown. Processing performance of the system is evaluated by carrying out some applications on the system.
