Transpose of 8X8 matrix using intrinsics

Hello,
I am looking for an 8x8 or a 16x16 transpose of a matrix using SIMD operations through Intel intrinsics. Please let me know if such an instruction exists.

Thanks.

IPP library hasa set of highly optimizedfunctionsto do a matrix transpose. Unfortunately, there is nosuch
SIMD instruction(s).
