I have to approximate execution time of PowerPC and x86 assembler code.I understand that I cannot compute exact it dependson many problems (current processor state - x86 processor dicides internal instructions in microinstructions, memory access time obtainig code from cache of from slower memory etc.).
I found some information in Intel Optimization reference (APPENDIX C), but it does not provide information about all general purpose instructions. Is there any complete reference about it?
What about PowerPC processors? Where can I find such information?
