A design and implementation of a single-chip encoder/decoder using LZSE algorithm with dictionary search processor (DISP)

摘要

We design and implementation of a single-chip LZSE encoder/decoder using LZSS algorithm and entropy by using a 0.6μm CMOS technology. The dictionary search processor (DISP) used a 2K×8-bit on-chip memory in clock speed of 50MHz. This indicates that each one clock out of total 33 clocks is used for update the string window of dictionary, and the remaining clocks per duration are used for compressing each one of data by byte unit. Consequently, LZSE was guaranteed 46% of the average Co topression ratio that applied entropy coding to output of LZSS codewords. This indicates that it has performance more than 7% higher compression ratio than as in the LZSS method.
