Optimization on C64X+ simulator

Vishu Kumar

Hello guys,

I am trying to optimize a source code on C64x+ simulator. I have enabled the profile option and in the profile viewer I am getting 2 columns ..

1> CYCLE.CPU.EXCL

2>CYCLE.TOTAL.EXCL

Since CYCLE.TOTAL option includes cache misses,offchip memory access also, i am confused which of the above columns must be sorted for profiling a function? also only the CYCLE.CPU.EXCL can be controlled by the optimization techniques?

I am using only the simulator , not using the target board now...

Hi Vishu,

Are you using CCS v2/3 or CCSv4?

You should be seeing more than two columns. Are you purposely hiding the other columns in the view and only displaying total exclusive counts for cycle.cpu and cycle.total? As for which column is of interest, cycle.cpu takes into account stalls while cycle.total is as you mentioned. Totals is often useful when available.
