Performance Counter Issues Urgent!!

Altera_Forum · ‎07-12-2009

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.

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

--Performance Counter Report--

Total Time: seconds (1993414581 clock-cycles)

ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ

ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ

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.

Hello,

My program looks like this , certainly something is wrong, could you anyone let me know the details.

if (inverse)

{

PERF_RESET(PERFORMANCE_COUNTER_0_BASE);

PERF_START_MEASURING(PERFORMANCE_COUNTER_0_BASE);

PERF_BEGIN(PERFORMANCE_COUNTER_0_BASE,1);

scale = fix_fft(fi, fr, m-1, inverse);

PERF_END (PERFORMANCE_COUNTER_0_BASE,1 );

PERF_STOP_MEASURING(PERFORMANCE_COUNTER_0_BASE);

perf_print_formatted_report ((void *)PERFORMANCE_COUNTER_0_BASE, /* defined in "system.h" */

ALT_CPU_FREQ, /* defined in "system.h" */

1, /* How many sections to print */

"INVERSE FFT"

);

//sw_time_1 = alt_timestamp();

}

for (i=1; i<N; i+=2)

{

tt = f[N+i-1];

f[N+i-1] = f;

f = tt;

}

if (! inverse)

{

PERF_RESET(PERFORMANCE_COUNTER_0_BASE);

PERF_START_MEASURING(PERFORMANCE_COUNTER_0_BASE);

PERF_BEGIN(PERFORMANCE_COUNTER_0_BASE,1);

scale = fix_fft(fi, fr, m-1, inverse);

PERF_END (PERFORMANCE_COUNTER_0_BASE,1 );

PERF_STOP_MEASURING(PERFORMANCE_COUNTER_0_BASE);

perf_print_formatted_report ((void *)PERFORMANCE_COUNTER_0_BASE, /* defined in "system.h" */

ALT_CPU_FREQ, /* defined in "system.h" */

1, /* How many sections to print */

"FFT"

);

Same Problem here...

I think the problem is the perf_print_formatted_report.

If I choose the "Small C Library" the code works. If not, then there is the garbage.

Also if you look at the perf_print_formattec_report.c the Nios IDE complains that there are syntax errors.

Anybody got a workaround?

So check the "Small C Library" option and build the project, and then uncheck it, build the project again, the counter_report will work fine.
