Consider the execution of the following loop. Assume whole loop instructions are loaded to the cache memory. The main memory accesses are only required to fetch the data in each instruction. a) b) for (i = 0; i < 2N; i++) a[i] = 0; for (i = 0; i <2N; i++) b[i] = c[i] + y; How many memory accesses are required to execute this loop? How can we improve the CUP performance by reducing the number of memory accesses? Rewrite the above loop and answer with the number of memory accesses for your new loop.
