Video signal processor configuration by multiprocessor approach

A real-time video signal processor (VSP), suitable for VLSI implementation, is proposed. In order to obtain software controllability for video signal processing in a real-time environment, the VSP employs a multiprocessor configuration, where a plural number of video signal processing modules (VSPMs) are connected to input, output and feedback buses. Each VSPM processes its own assigned sub-images without communicating from/to other VSPMs. As the VSP needs no overhead for VSPM communication, the number of VSPMs involved does not affect the VSP system performance. The homogeneous processor based approach, employed in VSP, will become the most suitable LSI implementation methodology in the near future, due to processor module regularity and system flexibility.
