Abstract:
1. An ASIC, comprising: a DMA arbiter to parse color plane data, sending each color plane's data to a DMA associated with each color plane; a compressor, to receive color plane data from the DMA associated with each color plane and to compress color data in runs, seedrow copies and literals, thereby forming compressed data; a decompressor to decompress the compressed data, the decompressor comprising: a decompressor core to direct data decompression; a state machine, operating within the decompressor core, to recognize and decompress runs, seedrow copies and literals; and a look-ahead buffer to contain compressed pixel data for use in loading Boolean equations within sequence of prioritized equations within the state machine; wherein the decompressor is configured to decompress data at one pixel per clock cycle of the ASIC.
