SPE-4k System

Summary

A visual processing system for early vision using massively parallel processing is developed. The system named SPE-4k (Sensory Processing Element- 4k) has 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 microseconds. 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. Processing performance of the system is evaluated by carrying out some applications on the system.
