A Parallel VLSI Video/Communication Controller

This paper presents a VLSI architecture specifically designed as a video/communication controller to support emerging applications in the area of video/data communications. The controller is a parallel architecture consisting of three (3) processing modules, a shared memory with four (4) banks and two (2) input/output modules and operating at the transfer speed of 622 Mbits/sec. The processing modules and memory banks communicate through a low cost interconnection scheme able though to perform at system's required data transfer rate. The entire system constitutes a component which can accommodate a switching system as an intelligent buffer with real time processing and multiplexing capabilities. The component performs operations on fixed and/or variable length packets of data on a stream basis. The architecture embeds both the processing and the memory modules, thus producing a “ system on a chip ” solution.
