Intrinsic Function in C++?

Discussion in 'C++' started by Bryan Parkoff, Nov 10, 2006.

  1. Do you know where I can find a good book how to write intrinsic
    function? Intrinsic function is useful to use MMX or SSE or any SIMD
    instruction of x86 and other machines for best portability. It is what I
    intend to write C++ code using intrinsic to develop video processing.

    This is compiler specific. Intrinsics basically are language constructs
    that the compiler uses to do "special" things.

    I think you need to ask yourself why you should even bother.
