AHA3430

The AHA3430 is a high speed full duplex compression/decompression coprocessor in a single chip CMOS VLSI device. The device implements the StarLite algorithm, a lossless compression and decompression algorithm optimized for hardcopy applications and is functionally backward compatible to the AHA3410C. The algorithm typically attains average compression ratios over 13 to 1 for bitmap image data. A non-muxed microprocessor interface connects directly to various embedded processors. An additional synchronous 32-bit port transfers data at up to 160 MBytes/sec in DMA mode.
