AOCL-Compression is a software framework that provides lossless data compression and decompression methods specifically tuned and optimized for AMD “Zen”-based CPUs.
The compression and decompression methods supported by this library are LZ4, ZLIB/DEFLATE/GZIP, ZSTD, BZIP2, Snappy, LZMA, and LZ4HC.
Highlights of AOCL-Compression 5.1
- Introduced multithreaded APIs for GZIP and Raw Deflate formats.
- Improved single threaded compression performance for Bzip2, Snappy and decompression performance for Bzip2, Snappy, Gzip, ZSTD.
- AOCL_DECOMPRESS_FAST support extended to Snappy.
- Integrated third-party utilities: minigzip and zstd utility for benchmarking.
