ASTC Software Texture Compression / Decompression Algorithm

The OpenGL 4.3 and OpenGL ES 3.0 specifications are opening today and they will use the newly developed ASTC compression algorithm to compress the texture . I am wondering if there are any purely software implementations (best in C / C ++) of the algorithm. There are code snippets here but they only cover the random hash used at the core of the algorithm, the full article was not disclosed. I base one of my projects on the Squish project (DXT1 in software) and will be interested in how much ASTC will benefit. Thanks in advance if you have any resources.

There is a codec for ASTC on this website (malideveloper.com).

Source code is also included.

Hope this helps.
