The algorithm exhibits an average compression ratio over 13 to 1 for bitmap image data. The device supports simultaneous compression and decompression operations at 25 MBytes/sec each. A Non-muxed microprocessor interface connects directly to various embedded processors. An additional synchronous 32-bit port transfers data at up to 100 MBytes/sec. Scanners and print engine interfaces may optionally be connected to two 8-bit synchronous video ports for emerging multifunction laser printer and copier applications. Software simulation and an analysis of the algorithm for printer and copier images of various complexity are available for evaluation. FEATURES PERFORMANCE: 25 MBytes/sec compression/decompression rates 100 MBytes/sec burst data rate over a 32-bit data bus 25 MBytes/sec synchronous 8-bit video in and video out ports Simultaneous compression/decompression operation at full bandwidth Average 13 to 1 compression ratio for bitmap image data FLEXIBILITY: 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 Configurable I/O interface for DMA mode, Big Endian or Little Endian, and 32-bit or 16-bit bus widths Interfaces dir...
