Consider a system with 2 level caches. Access times of Level 1 cache, Level 2 cache, and main memory are 1 ns, 10ns, and 500 ns, respectively. The hit rates of Level 1 and Level 2 caches are 0.8 to 0.9, respectively. What is the average access time of the system ignoring the search time within the cache? (consider simultaneous access) 1. 2. 3. 4. 13.0 ns 12.8 ns 12.6 ns 12.4 ns

Given a computer using a byte-addressable virtual memory system with a two-entry TLB, a 2-way set associative cache, and a page table for a process P. Assume cache blocks of size 8 bytes. Assume pages of size 16 bytes and a main memory of 4 frames. Assume the following TLB and page table for Process P: TLB 0 Vali d 0 1 1 1 2 0 3 1 4 1 5 0 6 0 7 0 Assume process P generates a memory request with virtual address Ox12. What is its corresponding physical address? You may represent the address in binary or hexadecimal notation. 3 3 0 2 1 4 Page Table f 1

Take into account the following scenario: we have a byte-addressable computer with 2-way set associative mapping, 16-bit main memory addresses, and 32 blocks of cache memory. Since there are 8 bytes in a block, you can use that information to calculate how big the offset field has to be.

5. Given that the hit ratio of level-1 cache is 0.5 and the access time is 50ns, the hit ratio of level-2 cache is 0.3 and the access time is 300ns, the access time of the main memory is 2000ns, what are the CETA and NETA if 2-level cache is applied?
