Hi, I am running X86 architecture in SE mode. I ran various applications for a single core system using TimingSimpleCPU cpu_type and observed following in the stats file:
1. Total number of committed instruction are given by system.cpu.committedInsts or sim_insts. Both these values are same 2. The integer and FP operation counts are given by system.cpu.num_int_insts, system.cpu.num_fp_insts respectively 3. The memory references are given by system.cpu.num_mem_refs 4. Branch control instruction count is given by system.cpu.num_conditional_control_insts >From my understanding total number of instruction executed should be sum of integer, FP Mem references and branch-control instructions. But in the stats file,I observe that the system.cpu.committedInsts is always less than (cpu.num_int_insts + system.cpu.num_fp_insts + system.cpu.num_mem_refs + system.cpu.num_conditional_control_insts) Is that normal? What can be the possible explanation for the same? Regards, Aditya
