MPEG-decoder and MPEG decoding method with two memory controllers

摘要

An MPEG decoder and an MPEG decoding method with two memory controllers is capable of separately controlling compressed data and decoded data. An MPEG decoder decodes a compressed input data formatted in an MPEG type. The MPEG decoder comprises a compressed data memory controller and a decoded data memory controller. The compressed data memory controller is coupled to a compressed data memory and controls the compressed data. The decoded data memory controller is coupled to a decoded data memory, and controls the decoded data. Since the compressed data flow and the decoded data flow are divided, the memory transfer rate is increased, and also the memory control is simple. In addition, the compressed data are able to be stored within the MPEG decoder. Therefore, the high-performance of the MPEG decoder and the high quality of the image are possible.
