ABSTRACT:
A method and apparatus for fast and cost-effective digital video decompression is disclosed. The invention implements the inverse quantization, inverse discrete cosine transform and motion compensation functions for an MPEG decoder in a pipelined parallel processor. The IDCT and motion compensation functions are implemented to maximize parallelization by using partitioned arithmetic and logic operations in a superscalar microprocessor. This approach drastically reduces the total number of instruction cycles required to perform the IDCT and motion compensation functions.
