Sample programs for my article__.

__ http://0x80.pl/articles/simd-byte-lookup.html

Software

The main utility in is python script test.py. It accepts:

  • name of matching method,
  • list of hexadecimal values that represent a set.

Please refer to Makefile for sample invocations.

The script generates a C++ program with implementation of function that checks which bytes are present in the set. The program contains unit test which validates the generated procedure.

Type make to build and run several sample programs.

Caveats

Currently only SSE instructions are supported.
