You are building a computer system around a processor with in-order execution that runs at 1 GHz and has a CPI of 1, excluding memory accesses. The on

A processor's clock cycle can be no shorter than its slowest single step (the critical path). A cache access is one of the slowest steps: decode the i

Hit time is the time to find data that is in the cache: use the index to pick a set, read its tag(s) and data, compare tags, then choose the right blo

2. Victim Caches Victim cache holds data that has been deleted from the cache, in case it is needed again This is fully associative cache and can help to reduce misses with direct-mapped or set assoc...

Two NMOS are connected as shown here. What mode of operation (cutoff, linear, saturation) is M2 in? Vt for both MOS is 0.6V. Useful info: The side wit

The main idea is that L1 and L2 have different jobs, so they are intentionally designed differently.differently.$\\boxed{\\text{L1: optimize for speed

Assume we are using 32-bit address. L1 cache is direct mapped and size is 16KB, block size is 32B. L2 cache is 8-way set associative and size is 4MB,

Memory Reference는 CPU가 메모리 계층(Cache / Memory)에 한 번 접근하는 것을 의미한다. 주로 두 종류가 있다.A memory reference means one access to the memory hierarchy/cache.In thes

Which has the lower miss rate: a 16KB instruction cache with a 16KB data cache or a unified 32KB cache? Use the following data for number of misses pe
