Hi!

Is there any BLAS implementation optimized for e500/e500v2 core? I'm using Eigen which was giving me good results on Atom CPU and struggling with the performance.

Well, it refers to the e6500 core, which supports AltiVec, which is not supported by e500. e500 doesn't even have a proper FPU, only SPE instructions.
