getting time of program code in code tms320c6418

Gopal Sarkar,

On the C6000 platform, the 32-bit high-resolution time is calculated by multiplying the low-resolution time
(that is, the interrupt count) by the value of the period register and adding the current value of the timer
counter register.

To obtain the value of the high-resolution time you can call CLK_gethtime from your application code.
The value of both clock restart at 0 when the maximum 32-bit value is reached.

DSP/BIOS initialization takes place in two phases:

• During BIOS_init which runs before main.
• During BIOS_start which runs after your program returns from main.

For example, functions such as CLK_gethtime and CLK_getltime should not be called from main because the timer is not running.

#include <clk.h>
Uint32             timeCnt    = 0;

timeCnt = CLK_gethtime();

Thanks for your reply. I followed your instructions and wrote the following code. The problem is CLK_gethtime() funtion is returning same value all the time. What am I missing?

//---------------------------program code---------------------------

#include<stdio.h>
#include<string.h>
#include <math.h>
#include <std.h>
#include <clk.h>
#include "evm6418.h"

    Uint32 begin1=0, end1=0;

int delay_usec(int k)     //function for 1 microsecond delay
{
    int i=0,j=0;
    j= k * 23;
    for(i=0;i<j;i++)
    {}
    return;
}
 
main()
{
    call11();
}

call11()
{
    begin1=CLK_gethtime();
    delay_usec(10);
    end1 = CLK_gethtime();
    printf("begin = %u \t end= %u\n",begin1, end1);
}

//--------------------end of program code-----------------------------------

output:

begin=72       end = 72
