A COMPACT REAL-TIME VISION SYSTEM USING INTEGRATED MEMORY ARRAY PROCESSOR ARCHITECTURE

This paper describes Real-Time Vision System (RVS-2) which shows quite high performance for low-level image processing while it is implement ed in one-board type compact size with small power consumption, RVS-2 consists of an IMAP board, a video board and a host workstation, and t he IMAP board consists of eight highly-integrated IMAP LSI's and a ded icated control LSI(RVSC), The IMAP chip integrates 2 Mb image memory a nd 64 processing elements that operate in SIMD fashion. The RVSC chip has functions to carry out global data operations efficiently without interactions with the host workstation, as well as the functions for p roviding an instruction stream to IMAP chips, The peak performance of RVS-2 is 30 GIPS and most of basic image processing are carried out wi thin about 0.1-0.7 ms, which is about 50-300 times faster than the vid eo frame rate.
