Intel(R) Intelligent Storage Acceleration Library

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

Erasure codes - Fast block Reed-Solomon type erasure codes for any encode/decode matrix in GF(2^8).
CRC - Fast implementations of cyclic redundancy check. Six different polynomials supported.
- iscsi32, ieee32, t10dif, ecma64, iso64, jones64, rocksoft64.
Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.
Compression - Fast deflate-compatible data compression.
De-compression - Fast inflate-compatible data compression.
igzip - A command line application like gzip, accelerated with ISA-L.

Building ISA-L

x86_64:

Assembler: nasm. Version 2.15 or later suggested (other versions of nasm and yasm may build but with limited function support).
Compiler: gcc, clang, icc or VC compiler.

aarch64:

other:

Compiler: Portable base functions are available that build with most C compilers.

To build and install the library with autotools it is usually sufficient to run:

./autogen.sh
./configure
make
sudo make install

To use a standard makefile run:

make -f Makefile.unx

On Windows use nmake to build dll and static lib:

nmake -f Makefile.nmake

Other targets include:
