Hello.
I'm using C28x and Code Composer.
I want to extract a sum from an array of 20 Uint16 as fast as possible.
If I write the code
Uint16 SUM(Uint16* array) {
Uint16 sum; Uint16 index;
for(index=0;index<20;index++) sum = array[index];
return (sum);}
the dsp spent more time to execute the loop.
If I write
Uint16 SUM(Uint16 *array) {
Uint16 sum;
sum+=*array++;
sum+=*array++; ... (20-times)... return (sum);} The dsp spent about 20 instructions but the C-code is longer. Is there a way to use for-loop and tell the compiler to unroll the loop ? Thankyou in advice
