Github repositories

I've put source code for my two articles at github:

• SSSE3: fast popcount --- repository
• SSE4 string search - modification of Karp-Rabin algorithm --- repository

Repositories contain original code, read: C99, 32-bit for GCC with inline assembly and also new programs in C++11 using intrinsics, tested in 64-bit environment.


BTW the article about popcount has gained popularity, and I hope another crazy idea about hacking MPSADBW will spread all over the world.

Asymmetric numeral systems

Very interesting idea: Asymmetric numeral systems: entropy coding combining speed of Huffman coding with compression rate of arithmetic coding.

Set of great articles

Lockless Inc publish a lot of interesting, advanced articles. There are some low-level things, algorithms, threading, and many more. Definitely worth to read!
