Can you please tell me where should i change to get
the effect? I changed in
src/python/m5/objects/PhysicalMemory.py as follows:
"cpu_ratio = Param.Int(10,"ratio between CPU speed and
memory bus speed") "
Also changed "latency = Param.Latency('1ms', "latency
of an access")" but execution time is remaining
exactly same (by execution time i am referring to tick
value difference between program start and end)
