4 Consider an XYZ microprocessor with 16 Kbyte L1 cache. The miss rate for this cache is 36 and the hit time is 2 cc. That microprocessor also has an 8 Mbyte, on-chip L2 cache. 95% of the time, data request to L2 cache are found and its hit time is 14 cc. If data is not found in L2 cache, a request is made to a 4Gbyte main memory. The miss penalty at main memory is 1000cc and its hit time is 1.5ce. On average, the memory access time for the main memory is 3.5cc. Explain what is the cache memory and its Calculate the percentage of data found in main memory (hit rate).

Transcribed Image Text:4 Consider an XYZ microprocessor with 16 Kbyte L1 cache. The miss rate for this cache is 36
and the hit time is 2 cc. That microprocessor also has an 8 Mbyte, on-chip L2 cache. 95% of
the time, data request to L2 cache are found and its hit time is 14 cc. If data is not found in
L2 cache, a request is made to a 4Gbyte main memory. The miss penalty at main memory is
1000cc and its hit time is 1.5cc. On average, the memory access time for the main memory
is 3.5cc.
(a)
Explain what is the cache memory and its' purpose.
