66 MBytes/sec StarLite Simultaneous Compressor/Decompressor IC

AHA3431 is a high speed lossless compression coprocessor IC for the hardcopy systems on many standard platforms. The AHA3431 is functionally backward compatible to the AHA3411. Simultaneous compression and decompression, flexible interfaces and advanced banding support make this a unique solution for high performance Raster Image Processing (RIP) controller designs. Advanced banding support handles blank, uncompressed and compressed bands during decompression mode. Scan line and record length counters accommodate various print resolutions and band buffer sizes.
