PRODUCT BRIEF*
AHA3430 StarLite
40 MBYTES/SEC SIMULTANEOUS
COMPRESSOR/DECOMPRESSOR IC, 3.3V
The high speed compression coprocessor is a
single-chip CMOS VLSI device that implements a
lossless compression and decompression algorithm.
The algorithm exhibits an average compression ratio
over 13 to 1 for bitmap image data. The device sup-
ports simultaneous compression and decompression
operations at 40 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 160 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.
APPLICATIONS
• Multifunction printers and copiers
• High performance laser printers and digital
copiers
