Implementation of LZMA compression algorithm on FPGA

摘要

In the era of big data, compression techniques are needed to improve data processing bandwidth and data storage efficiency. Compared with software-based compression techniques, hardware-based compression techniques can improve speed and reduce power consumption. LZMA (Lempel-Ziv-Markov chain algorithm) is a lossless compression technology, and its hardware implementation has broad application prospects. A novel high-performance implementation of the LZMA compression algorithm capable of processing up to 125 Mbit/s on a Virtex-6 field programmable gate array (FPGA) chip is proposed. A typical application and its compression performance for a specific data sample are then presented.
