Question: 7. Calculate the memory access time for an 8-bit word if your Level 1 Cache Hit Rate is 98% and Level 2 Cache Hit Rate

7. Calculate the memory access time for an 8-bit word if your Level 1 Cache Hit Rate is 98% and Level 2 Cache Hit Rate is 99.9%? Memory access time for a byte is 100 nanosecond and cache access times are 1 nsec for Level 1 and 10 nsec for Level 2. Memory Hit Rate is 95% and the disk drive takes 50 msec to access a byte. The CPU is a 1 GHz processor. Be specific in your assumptions.

9. Calculate the memory access time for an 8-bit word if your Level 1 Cache Hit Rate is 99%, Level 2 Cache Hit Rate is 98%, and Level 3 Cache Hit Rate is 95%? Memory access time for a byte is 200 nanosecond and cache access times are 2 nsec for Level 1, 10 nsec for Level 2, and 50 nsec for Level 3. Memory Hit Rate is 99.1% and the disk drive takes 100 msec to access a byte. The CPU is a 1 GHz processor. Be specific in your assumptions.

11. Calculate the average Disk access time for an 8-bit word if your Level 1 Cache Hit Rate is 99%, Level 2 Cache Hit Rate is 98%, and Level 3 Cache Hit Rate is 95%? Memory access time for a byte is 200 nanosecond and cache access times are 2 nsec for Level 1, 10 nsec for Level 2, and 50 nsec for Level 3. Memory Hit Rate is 99.1% and the disk drive takes 100 msec to access a byte. The CPU is a 1 GHz processor. Be specific in your assumptions.
