Abstract

A multiprocessing system that can operate at video rate on inputs from television cameras or VTRs has been developed. This system, called the real-time video signal processor (RTVP), consists of identical processing units (PUs) and can be used in a wide range of image-processing applications. System performance is increased in proportion to the number of PUs connected by simple unidirectional video transfer lines. The RTVP uses a replicated memory system in which the same image data is written in the frame memory of each PU, eliminating the problem of memory access contention. A new time-base processing method for synchronizing an external video signal to the system timing is applied.
