 Comtech AHA Corp. 
Part Number : AHA3520
Overview :
The AHA3520 is a single-chip CMOS lossless compression and decompression integrated circuit. The device implements the ALDC compression algorithm defined by various industry standards.This algorithm is also known as Adaptive Lossless
Data Compression.
Features : - PERFORMANCE:
- • 20 MBytes/sec data compression, decompression or pass-through rate
- • 2 to 1 average compression ratio
- • Multiple byte transfers without microprocessor intervention
- • Error checking in decompression mode reportable via an interrupt
- FLEXIBILITY:
- • In-line or look-aside system architectures supported
- • Polled or interrupt driven I/O
- • Two independent DMA ports programmable for 8 or 16-bit transfers
- and handshaking modes
- SYSTEM INTERFACE:
- • Single-chip data compression solution
- • Programmable interrupts
- • Interfaces directly with industry standard SCSI chips
- OTHERS:
- • Industry standard ALDC adaptive lossless
- compression algorithm
