Hi All,

I have some serious problems in usage of performance counters, could anyone please let me know what could have gone wrong.

I have included the associate header files. Some junk value is coming ,dont know why. Some data corruption had happened, or the prints not working.

try using like this

int main()

{

PERF_RESET(PERFORMANCE_COUNTER_1_BASE);

PERF_START_MEASURING(PERFORMANCE_COUNTER_1_BASE);

call your function here

PERF_STOP_MEASURING(PERFORMANCE_COUNTER_1_BASE);

alt_u64 time2 = 0;

time2 = perf_get_section_time((void *)PERFORMANCE_COUNTER_1_BASE, 1);

printf("IT TOOK T1: Main Loop : %d cycles\n", time2);

}

in your function say

multiply()

{

PERF_BEGIN(PERFORMANCE_COUNTER_1_BASE,1);

you code for perfomance here

PERF_end(PERFORMANCE_COUNTER_1_BASE,1);

}

select how many section you want o measurein perfomance counter unit.
