3.1 Considering that the TLB takes 5 ns access time and main memory takes 200ns, compute the Effective Access Time (EAT) for the following case: Number of hits to the TLB is 95%.
3.3 If there is a miss in the TLB, how many I/O operations could be generated?
Homework Answers
(3.1)
TLB access time = 5 ns
Main memory access time = 200 ns
TLB hit rate = 95%
Effective Access Time (EAT) = 0.95*(5+200) + 0.05(5 + 200 +
200)
=> 0.95*205 + 0.05*405
=> 194.75 + 20.25
=> 215 ns
(3.3)
If there is a miss in the TLB, Number of I/O generated = 2

A computer uses virtual memory implemented by paging. The TLB lookup takes 100 ns and the update takes 200 ns. The PT lookup takes 1 µs and the update takes 2 µs. Loading a word from main memory onto the CPU takes 10 µs and loading a page from the disk into main memory takes 10 ms. The TLB hit ratio is 0.4 and the main memory hit ratio is 0.3. Compute the average access time for a referenced word:...

Q5. Consider a memory system where all pages fit in memory. The TLB takes 15 nanoseconds to access and memory takes 120 nanoseconds to access. What is the effective access time for 1 level paging if the hit rate is 65%? What if it’s 95%? What is the effective access time if not all processes fit into memory and the swap time is 850,000 nanoseconds for a page fault?

virtual memory support into our baseline 5-stage MIPS pipeline using the TLB miss handler. Assume that accessing the TLB does not incur an extra cycle in memory access in case of hits. Without virtual memory support (i.e. she had only a single address space for the entire system, or a physical address is same as a logical address), the average cycles per instruction (CPI) was 2 to run Program X. If the TLB misses 10 times for instructions and 20...

Consider a demand-paging system in which the replacement of a page takes 20 milliseconds (access time and data transfer). Addresses are translated through a page table in main memory, with an access time of 1 microsecond per memory access. Thus, each memory reference through the page table takes two accesses. To improve this time, a TLB is added to the system to reduces access time to one memory reference, if the page-table entry is in the associative memory. Assume that...

6. Memory Access Time [15 points] Consider a MIPS processor that includes a cache, a main memory, and a hard drive. Access times of cache memory, main memory, and hard drive are 5 ns, 200 ns, and 1000 ns, respectively. Assume that cache memory is divided into instruction cache and data cache. Assume that data cache has a 90% hit rate. Assume that main memory has a 98% hit rate and hard drive is perfect (it has a 100% hit...
