LZO Accel-D

LZO Data Decompression Core/ Lossless Data Decompression IP Core

LZOAccel-D is an FPGA hardware implementation of a lossless data decompression engine, compatible with the LZO 2.10 standard.

The Core receives compressed input data blocks and produces decompressed data blocks. The Core analyzes the header and tail of the data blocks, checks for errors in the input data blocks, and outputs the decompressed data payload, so users do not need to process compressed data blocks. Based on the detailed error tracking and reporting features, the Core can smooth system operation and achieve error recovery even if errors occur in compressed data blocks.

Based on the fast processing characteristics, the Core can output 2 bytes of decompressed data per clock cycle on average, providing a decompression rate of 4.8Gbps. Users can instantiate multiple Cores to further improve the system throughput.

LZOAccel-D uses the AMBA AXI4-Stream data interface, which is very easy to use and integrate. LZOAccel-D can run offline and independently, freeing up the CPU for data decompression intensive tasks.
