I have added profiling to arp32 test app code using TSC. I have observed in the sample test app codes provided by TI, the difference(t0 - t1) is being divided by 1000000 . Can anyone please let me know why it is being divided by 1000000 ?

t0 = _tsc_gettime();
/* CODE TO BE PROFILed */
t1 = _tsc_gettime();
time_taken = ((t1 - t0)*2)/1000000;

Hi,

Can you point to the source code location? I'm not able to figure it out.

Mention the Vision SDK version.

We recommend you to go through the below thread for profiling in the vision SDK

Thanks

Source code location : /COMMON/eve_sw_01_20_01_00/apps/filter_2d/test/src/filter_2d_tb.c

Line number : 779

I just wanted to know why "profile_tsc" is divided by 1000000.

Hi,

Seems they are representing in Mcycle.

If you want to profile in the EVE follow the below method

uint64_t tsc_start, tsc_end;
uint64_t tsc_cycles;

tsc_start = _tsc_gettime();

// code

tsc_end = _tsc_gettime();


tsc_cycles = tsc_end - tsc_start;

printf("#### tsc_cycles = %ld\n",tsc_cycles", tsc_cycles);

Thanks

Gaviraju
