Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. Lossless compression is used when it is important that the original and the decompressed data be identical, or when no assumption can be made on whether certain deviation is uncritical. Typical applications include data storage and transmission.
LZR1 implements the lossless compression algorithm on short units of data (“frames”). The core supports frame sizes up to 4096 bytes.
The design is fully synchronous and available in multiple configurations varying in bus widths and throughput.
LZR1-6 can easily deliver 10 Gbps of throughput in both FPGA and ASIC implementations. The compression ratio greatly depends on the data and somewhat depends on the frames size; on typical file corpuses varies between 1.5 and 2.
