Abstract:
A semiconductor chip implementing hardware for use in video data compression-decompression (codec) systems using table-based compression algorithms, comprising:a video input/output port adapted to receive and supply digital video data from/to an external video encoder-decoder;a first memory interface coupled to said video input/output port, said first memory interface adapted to interface with a first external memory device that stores coefficients for the table-based compression algorithm;a second memory interface coupled to said first memory interface, said second memory interface adapted to interface with a second external memory device that stores data corresponding to a video frame; anda computer interface coupled to said second memory interface, said computer interface being capable of communicating with a host computing system via a bidirectional bus,wherein, the semiconductor chip in combination with the external memory devices performs a video data compression-decompression using a table-based vector quantization algorithm.
