    instruction cost needed in clock cycles for ia-32 architecture

    nuliknol

      Hi,

      I am looking for a list of cost of instructions  expressed in clock cycles.

      Like for example:

      CMOV <-- takes 1 clock cycle to execute

      MOVDQA <-- takes 3 clock cycles to execute.

       

      Is this data available?

      As I have checked the Architecture Software Developer manual does not contain this information and I need it because I am developing an application optimized for speed.

       

      Thanks very much in advance.
