Description

Since support of IPP has been removed from cvMul, cvDiv, the performance degraded seriously.

On core/src/arithm.cpp@HEAD I observe that binary and add/subtract matrix operations (bitwiseOp_(...)) are now optimized using SSE/SSE2, while multiplication and division (mul_(), div_()) are not.
