A.

Program Plan Intro

Given C Code:

void copy_array(long *src, long *dest, long n)

{

long i;

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

dest[i] = src[i];

}

Cycles per element (CPE):

  • The CPE denotes performance of program that helps in improving code.
  • It helps to understand detailed level loop performance for an iterative program.
  • It is appropriate for programs that use a repetitive computation.
  • The processor’s activity sequencing is controlled by a clock that provides regular signal of some frequency.
