At 160 Megabytes per second, the storage compression standard just got a lot faster

Introducing the high performance Hifn™ 9620 lossless data compression processor The 9620, using Hifn’s industry-standard LZS® algorithm, can compress or decompress data at up to 160 Mbytes/s, fast enough to support SCSI-3 devices. The 9620 verifies every packet, delivering 100% accuracy on your data. More importantly for system designers, the 9620 is easy and straightforward to design into their systems. The system bus interface supports both register I/O and DMA transfers at a bus width of 16 bits, and the DMA interface supports single-cycle bus transfers at a bus clock of up to 80 MHz.

LZS—the industry standard—available from Hifn
The 9620 implements the industry standard Hifn LZS data compression algorithm. This algorithm has been standardized by many organizations including: IETF (RFC 3173, RFC-1974, RFC-1962, RFC-1967) Frame Relay Forum (FRF.9) ANSI (X3.241), and QIC (122).

In addition, LZS has become the de facto standard in tape drives. Companies rely on LZS to ensure the most efficient, highest performing compression technologies for their devices.

CPU intervention is not required between operations, eliminating any latency issues. Record can be queued, reducing CPU intervention. The 9620 contains input and output FIFOs, separate compression and decompression engines, dedicated internal compression memory, and command, status, and result registers. The 9620 has a fault detection feature that verifies the results of the compression engine in real time.
