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.
- 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.

- Make: GNU 'make' or 'nmake' (Windows).
- Optional: Building with autotools requires autoconf/automake packages.
- Optional: Manual generation requires help2man package.
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:
- Assembler: gas v2.24 or later.
- Compiler: gcc v4.7 or later.
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
or see details on setting up environment here.
