Two optimized implementations for PowerPC platformsPosted on October 4th, 2010 No comments
We present here two optimized implementations for PowerPC platforms, in 32-bit and 64-bit modes. They offer a speed increase of about 30% over the optimized C implementation of Shabal.
These implementations do not use AltiVec. The 32-bit implementation is thus compatible with the oldest PowerPC systems, including the 603e. Hashing speed was measured to be about 9.1 cpb on a PowerPC 750 (aka “G3″).
