Re: [Gems-users] How to Calculating IPC

[Leontie Eugen <e_leontie@xxxxxxxxx>]

Simics (without any cache or microarchitectural addition - like Ruby or Opal ) will only provide functional simulations. 
In short , you can not compute any significant IPC with only Simics. The "cycles" reported by simics when you do run the command ptime are just the default IPC=1. 

You will only compute a meaningful IPC if you have both a microarchitecture simulator and a memory hierarchy simulator.

Subject: [Gems-users] How to Calculating IPC

Dear all;

Can anyone tell me how I can calculate IPC of an application with simics without ruby and opal?
If it is essential to have ruby and opal, would you please tell me how I can reach IPC?

Thanks in advance for your help
