clock cycles for integer multiplication and addition in core 2 duo processor

Hello,

I have an Intel core 2 duo processor (E6400 2.13Ghz 2GB RAM)

How many clock cycles does an integer addition and an integer multiplication each take separately for my core 2 duo?

I suppose core 2 duo is a 14 stage pipeline.

thanks,

prads

Take a look at "Intel 64 and IA-32 Architectures Optimization Reference Manual":

www3.intel.com/design/processor/manuals/248966.pdf

There are latencies and throughputs of most instructions (Appendix C).
