Overview

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.

Evaluating Lossless Data Compression Algorithms and Cores

Data compression plays a critical role in modern computing, enabling efficient storage and faster transmission of information. Among lossless data compression algorithms, GZIP, ZSTD, LZ4, and Snappy have emerged as prominent contenders, each offering unique trade-offs in terms of compression ratio, speed, and resource utilization. This white paper evaluates these algorithms and their corresponding hardware cores, providing an in-depth comparison to help developers and system architects choose the optimal solution for their specific use case.

Firmware Compression for Lower Energy and Faster Boot in IoT Devices

The phrase “IoT” for Internet of Things has exploded to cover a wide range of different applications and diverse devices with very different requirements. Most observers, however, would agree that low energy consumption is a key element for IoT, as many of these devices must run on batteries or harvest energy from the environment.
