Abstract :
We developed a video multiprocessor (VMP) for image compression and decompression schemes of MPEG (especially MPEG-2) in this study. The VMP would apply to programmable architecture. Various flexibilities to implement real-time image compression algorithm, and many other applications such as DVD-CD ROM authoring tool and videophone/teleconferencing systems. I/O architecture of the VMP is designed for the multi processor functionality which uses many VMPs according to required arithmetic quantities of the system. Further, the architecture of the VMP system is simplified by processing the necessary peripheral I/O operations within the processor
