Basicly, the performance counter component will calculate the time and clock taken between the time you start and stop this component. So you can use it to calculate how fast your function is, and then report it in detail, you can easily use it for performance test.

It comes with very useful API: 

PERF_RESET(p)
PERF_START_MEASURING(p)
PERF_STOP_MEASURING(p)
PERF_BEGIN(p,n)
PERF_END(p,n)
int perf_print_formatted_report (void* perf_base, alt_u32 clock_freq_hertz, int num_sections, ...)

See attached document for more detail.

Hope this will help you.
