Consider a microprocessor with a 16 Kbyte Ll cache. The miss rate for this cache is 3% and the hit time is 2 CCs. The processor also has an 8 Mbyte, on-chip L2 cache and the hit time is 15CC. 95% of the time, data requests to the L2 cache are found. If data is not found in the L2 cache, a request is made to a 4 Gbyte main memory and the hit time is 200 CCs. The time to service a memory request is 100,000 CCs when there is a miss in Main memory. On average, it takes 3.5 CCs to process a memory request. How often is data found in main memory(Hit Rate in percentage) ?
