Hello,
i have written a vectorized code using c intrinsics for Turbo product decoder  (Used as a FEC ) on altivec unit...i have no idea how to benchmark it.i mean how many cycles, instruction count ,%usage of various  altivec sub units consumed during execution of the vectorized code.i went through the apple  website ..n got simg4 tools ,but it was for Mac OS .can u suggest me the way around this for Windows ..i have used MPC7447A @1GHz for evaluating  the performence of vectorized code.

thanx in anticipation.
