+ Timings are in CPU Core cycles
+ Inst_Min: Minimum Excution time during the display update interval(default is ~1 second)
+ Inst_Max: Maximum Excution time during the display update interval(default is ~1 second)
+ Inst_jitter: Jitter in the Excution time during rhe display update interval. This is the value of interest
+ last_Exec: The Excution time of last iteration just before the display update
+ Abs_Min: Absolute Minimum Excution time since the program started or statistics were reset
+ Abs_Max: Absolute Maximum Excution time since the program started or statistics were reset
+ tmp: Cumulative value calcualted by the dummy function
+ Interval: Time interval between the display updates in Core Cycles
