Moving picture decoding processor for multimedia signal processing

A moving picture decoding processor for multimedia signal processing comprising:

• an RISC processor for carrying out an overall control on decoding process of compressed moving pictures inputted from exterior;
• a video decoder (VDEC) for decoding moving pictures;
• a post processor for carrying out an appropriate post processing on decoded moving picture signals according to the output device connected to exterior;
• a DSCU (Decoding Sequence Control Unit) DMA (Direct Memory Access) for interfacing said VDEC and an external memory;
• a post DMA for interfacing said post processor and an external memory;
• peripheral devices required for system application;
• a peripheral device DMA for interfacing said peripheral devices and an external memory;
• an external memory controller for controlling said external memory;
• a peripheral device bridge for interfacing a local bus, to which said peripheral devices are connected, and a main bus;
• and
• a main bus, a coprocessor bus and a peripheral device control bus, which are independent from one another and interfacing said components respectively.
