LZS is the de facto data compression standard for networking. You can obtain LZS in C or assembly language software libraries. The LZS221 Data Compression Software Library provides a highly optimized software implementation of the Hifn LZS algorithm in assembly source code for the Intel 386 family of processors. This library is also compatible with other members of the LZS221 software family. Files compressed or decompressed with hardware or software may be compressed or decompressed interchangeably with hardware or software.
Assembly language optimized implementations for other specific processors are also available.
In addition, a C source code version is available that can be used to create a compression library for any processor.
