Palo Alto, CA (PRWEB) June 22, 2010
IP Cores, Inc. (http://www.ipcores.com) has shipped another version of its high-speed lossless data compression IP core.
"Our new core in the LZR1 family of cores supports lossless data compression with large block size ," said Dmitri Varsanofiev, CTO of IP Cores. "As all other cores in the LZR1 family, the core is scalable with throughputs of 10 Gbps easy to achieve in both ASIC and FPGA".
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 Family of Cores
LZR1 implements the lossless compression algorithm on short units of data ("frames"). The core supports configurable maximum frame sizes. The design is fully synchronous and available in multiple configurations varying in bus widths and throughput.
LZR1 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.
LZR1 datasheet is available on the IP Cores, Inc. Web site at http://ipcores.com/lzr1_lossless_compression_ip_core.htm.
