MPEG video decompression processor |
摘要 |
A method and a structure are provided to decode intra-frame and interframe coded compressed video data. In one embodiment of the present invention, a decompression structure having a processor is provided with a global bus over which a decoder coprocessor, an inverse discrete cosine transform coprocessor and a motion compensation coprocessor communicate. The decompression structure in accordance with the present invention communicates with a host computer over a host bus and with an external dynamic random access memory over a memory bus. The processor in the decompression structure of the present invention provides overall control to the decoder, IDCT and motion compensation coprocessors by reading and writing into a plurality of data and control registers, each register associated with one of the decoder, the IDCT and the motion compensation coprocessors.
