The Lempel-Ziv (LZ) compression methods are among the most popular algorithms for lossless data compression. LZ methods use a table based compression model where table entries are substituted for repeated strings of data.
LZRW3 is a well known LZ-type algorithm developed by Ross Williams in the 1990s which offers a useful combination of high throughput and good compression performance. It also has the advantage of being very efficient to build in hardware, unlike the majority of compression algorithms which tend to favour software implementations.
The Helion LZRW3 core implements the LZRW3 data compression algorithm in Altera FPGA without the need for external memory storage. It is capable of handling data throughputs in excess of 1 Gigabit/sec, and is ideal for use for improving system performance and efficiency in data communications, networking and data storage applications.
