QUESTION
I-cache miss rate 3%. D-cache miss rate 5%. 40% of instructions reference data. miss penalty of 50 cycles. Base CPI is 2. How can I know what is the
- I-cache miss rate 3%.
- D-cache miss rate 5%.
- 40% of instructions reference data.
- miss penalty of 50 cycles.
- Base CPI is 2.
How can I know what is the CPI including the misses?
How much slower is the machine when misses are taken into account?
if the I-miss penalty is reduced to 10 (D-miss still 50) ?
If the clock rate is 100MHz, how many instructions are executed per second?
With I-miss penalty back to 50, what is performance if CPU (and the caches) are 100 times faster?
