Consider Listning 1 on the last page. Assume the code is executed on a 32-bit MIPS processor that includes an instruction cache with the following properties: Capacity 512 bytes, direct mapped, block size -8 bytes. Assume that the cache is empty (all valid bits are zero) before you call function sum (a) Will the instruction cache utilize temporal locality or spatial locality, or both? (b) What is the instruct cache miss rate when executing the function? Only count the memory accesses within the function, that is, the first instruction in the function is xor and the last one jr. The function is called with the following C statement i an 0x00400000. Answer as a rational number. Consider Listning 1 on the last page.
