Abstract :
A single-chip implementation of the Lempel-Ziv adaptive data compression algorithm in 1.2-μm CMOS technology is described. The chip uses 2K-byte on-chip content addressable memory (CAM)/SRAM for storing the most recent input characters to which the incoming string is compared against and referenced. It performs compression or decompression on byte-oriented input data at a data rate of one byte per clock cycle, except when one out of every 33 cycles is used to update the string dictionary
