Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of algorithms in different compression methods applications. In a distributed environment, large data files remain a major bottleneck. Compression is an important component of the solutions available for creating file sizes of manageable and transmittable dimensions. When high-speed media or channels are used, high-speed data compression is desired. Software implementations are often not fast enough. In this paper, the authors present the Very high speed Hardware Description Language (VHDL) modeling environment of Lempel-Ziv-Welch (LZW) algorithm for binary data compression to ease the description, verification, simulation and hardware realization.
