C6713 profiling

Started by Quan Nguyen March 7, 2006
Hi everybody,
 
I want to profile my program on TMS320C6713 and I found some instructions in "spru198g.pdf" , page 41-42.
 
1) In section 2.3.1.1 , they talk about the command :
 
                                     load6x g example.out
 
    How can I input this command ?
    Do I have to change some configuration in my project ?
 
2) In section 2.3.1.2 , the talk about "clock()" but when I used it , the number of clocks is always 0.
 
-----------------Here is my code--
 

#include <stdio.h>
#include <time.h>                                   /* need time.h in order to call clock()*/

void computing()
{
 time_t  t0, t1;
 clock_t c0 , c1;
 long count;

 double a, b, c;

 t0 = time(NULL);
 c0 = clock();
 
 for (count = 1l; count < 10000000l; count++)
 {
  a = sqrt(count);
  b = 1.0/a;
  c = b - a;
 }

 t1 = time(NULL);
 c1 = clock();

 printf("\n%d clocks per second\n" , (int)CLOCKS_PER_SEC);
 printf("\n The number of clocks  : %d\n" , (int)c1 - (int)c0);
 printf("\n Time to perform       : %f\n" , (float)((int)c1 - (int)c0 / CLOCKS_PER_SEC));


 
}

void main()
{
 computing();
}

----------------- Here is the output---------------------------------

200000000 clocks per second

 The number of clocks  : 0

 Time to perform       : 0.000000

------ 

           Did I call "clock()" in a wrong way ?
 
Thank you,
 
Quan
