com comtech aha corporation PRODUCT BRIEF* AHA3422 StarLite 16 MBYTES/SEC LOSSLESS DECOMPRESSOR IC AHA3422 is a high speed lossless decompression coprocessor IC for the hardcopy systems on many standard platforms, including the PCI Bus.
The device offers a low cost decompression only solution for under 30 ppm printers or 50 ppm copiers at 1200 dpi.
High speed decompression, flexible interfaces and advanced banding support make this a unique solution for Raster Image Processing (RIP) controller designs.
Advanced banding support handles blank, uncompressed and compressed bands.
Scan line and record length counters accommodate various print resolutions and band buffer sizes.
Software simulation and an analysis of the algorithm for printer and copier images of various complexity are available for evaluation.
