How to use the Profile Clock for C55x.
I want to see the right usage of the Profile Clock.
I am using TMDX5535EZDSP in CCSv4.
CCS menu to enable the Profile Clock is "Target - Clock - Enable".
CCS menu to reset the Profile Clock is "Target - Clock - Reset".
I used the Profile Clock in two case for the following assembler cord.
mov hi(ac0),*ar1 || mov ac0,*ar3
mpym *ar0+,uns(*ar3+),ac0
macm uns(*ar0+),*ar1+,ac0
macm *ar0+,uns(*ar3+),ac0
macm uns(*ar0+),*ar1+,ac0
macm *ar0+,uns(*(ar3+t0)),ac0
macm uns(*ar0+),*(ar1+t0),ac0
macm *ar0+,uns(*ar3+),ac0
macm uns(*ar0+),*ar1+,ac0
macm *ar0+,uns(*(ar3-t0)),ac0
macm uns(*ar0),*ar1,ac0
amov #PreEQCoef1,ar0
asub #5,ar1
macm *(ar0+t0),*ar1+,ac0>>#16
macm *(ar0+t0),*ar1+,ac0
macm *(ar0+t0),*(ar1+t0),ac0
macm *(ar0+t0),*ar1+,ac0
macm *(ar0+t0),*(ar1-t0),ac0
sfts ac0,#2 || mov #4,t1
sat ac0
mov hi(ac0),*ar1 || mov ac0,*ar3
The first case, I put a breakpoint in the first line and the last next line each and ran the program.
When stop at the breakpoint of the first line, I reset the count of the Profile Clock.
When stop at the breakpoint of the last next line, I watched a result, it is 24.
The second case, I run the program by single-step.
When stop at the first line, I reset the count of the Profile Clock.
When stop at the last next line, I watched a result, it is 21.
Why is it that results were different?
Best regards,
Daisuke
