How to convert TSC cpu cycles into seconds ?
unsigned long long tsc_start, tsc_end;
tsc_start = get_tsc();
// execute some code
tsc_end = get_tsc();
printf("Total time for execution %llu cpu cycles", tsc_end - tsc_start);
printf("Total time in seconds ") ; // How to compute this ?
static unsigned long long get_tsc()
unsigned long long tsc;
asm volatile ("rdtsc" : "=A" (tsc));
