Abstract

We present a software implementation of a real-time MPEG video codec on the MediaStation 5000 multimedia system. Unlike other compression systems whose sole function is the encoding or decoding of video data, the MediaStation 5000 is capable of performing various real-time operations involving a wide range of multimedia data, including image, graphics, video, and even audio. This programmability is provided by Texas Instruments TMS320C80, better known as Multimedia Video Processor (MVP), which is a single-chip multiprocessing device with highly parallel internal architecture. The MVP integrates a RISC processor, four DSP-like processors, an intelligent DMA controller, video controllers, and a large amount of SRAMs onto a single chip. Since the MVP contains such a high degree of parallel features, developing the MPEG software and mapping it to the MVP requires a thorough study of the algorithms and a good understanding of the processor architecture. By exploiting the advanced features of the MVP, the MediaStation 5000 can achieve the MPEG compression and decompression of video sequences in real time.
