Reverse-engineered KNI Documentation

Clive Turvey has continued his investigation into KNI, and has documented the instructions he has found so far. MMX coders will be happy to see that KNI contains a 1-cycle shuffle instruction, like Altivec does, but unlike MMX. As expected it has some instructions specifically for 3D (1/x and 1/sqrt(x)). Update: 02/24 12:11 by S : As reader Christopher Thomas points out, Intel has released a manual that includes a functional description of KNI. But I can't find any instruction timings in it. It weighs a hefty 5.5Mb.
