Lot of cycle taken to execute simple for loops in DM6437 - CCS 3.3.38.2

prashanth hs

Void f1(struct t1 *p1,struct t2 *p2,struct t3 *p3,struct t4 *p4)

{

char *temp = p3->data;

char *temp1 = p1->data;

for(i=0;i<479;i++)

{

for(j=0;j<720;j++)

{

temp = temp1; // around 20,000 cycles

temp++;

}

Compiler Option Set to : -O3

Prashanth,

In the above code, just (temp=temp1) - this should not be taking 20000 cycles.

You can view the code as mixed of Source and Assembly in CCS, to understand better.

May I know what you are trying to achieve. You can leverage lots of specialized applications :
