A microprocessor has 32-bit machine language instructions and 32-bit physical addresses. The instruction cache is a direct-mapped cache which contains 8192 slots. The control bits for each slot are a valid bi t and a modified bit. A cache block is 4 bytes. Consider the instruction cache described in Figure 1. What is the total number of bits in one cache slot? A) 47 bits B) 49 bits C) 51 bits D) 53 bits E) None of the above. Consider the instruction cache described in Figure 1. Which of the following statements about organization correct? A) It exploits temporal locality, but not spatial locality. B) It requires two 30-bit comparators per slot. C) It exploits spatial locality, but not temporal locality. D) It requires four 30-bit comparators per slot. E) It exploits both temporal locality and spatial locality
