Tick 75590 would be around 230 cpu cycles. If you get an instruction TLB
miss (assuming you run in FS mode) and/or have to go to main memory to
get your instruction then miss in the row buffer (assuming you use the
detailed model) this sounds reasonnable to me.

Hi all,
I am running a X86 detailed cpu
I set the clock at 3ghz. That means it takes 333 ticks for each clock
cycle.
I am running a binary that contains only a single instruction.
I printed out the trace for some reason the instruction is fetched at
75591th tick
75591: system.cpu T0 : @_start. 0 : MOV_R_I : limm eax, 0x3c :
IntAlu : D=0x000000000000003c
I dont understand why it takes so long for it to fetch the instruction.
Is this normal?
How can I fix this?
I will appreciate any help I can get. Thx in advance.
