A processor has a base CPI of 1.2. Every instruction requires one instruction fetch, and 30% of instructions are loads and 10% are stores.The L1 cache miss rate (same for...

can someone please tell me that when to use 1.h1(t1) + (1-h1)(t2)2.t1 + (1-h1)(t2)in finding Tavg

Given a computing system with two levels of cache (L1 and L2) and a main memory. The first level (L1) cache access time is $1$ nanosecond (ns) and the "hit rate" for L1 c...

A computer has a memory hierarchy consisting of two-level cache $\text{(L1}$ and $\text{L2)}$ and a main memory. If the processor needs to access data from memory, it fir...

Consider a system with hit ratio of a cache and main memory are 70% and 90% respectively cache memory access times is 60 ns. When miss in cache then 8 word block is trans...

Many symmetric multi-processor systems have different levels of caches; one level is local to each processing core, and another level is shared among all processing cores...

I have few doubts regarding $ L1$ and $ L2 $ cacheConsider there is sequential access to L1 and L2 cache i.e L2 is accessed after L1 misses$\textup{Doubt 1:}$Suppose we w...

A computer has a single cache (off-chip) with a $3$ ns hit time and a $95\%$ hit rate. Main memory has a $50$ ns access time. If we add an on-chip cache with a $0.6$ ns h...

Consider the following statements:(i) Accessing of data in a column wise fashion maintains spatial locality only when the block size is equal to the total size of the ele...

Which of the following statement is $\text{TRUE}$?Doubling the block size and halving the number of sets will reduce capacity missesThe last-level cache is designed for h...

Consider a two-level memory hierarchy, L1 (cache) has an accessing time of 5 ns and main memory has an accessing time of 100 ns. Writing or updating contents takes 20 ns...

consider two-level cache hierarchies with L1 and L2 cache. Programs refer to memory 1000 times out of which 40 misses are in the L1 cache and 10 misses are in the L2 cach...

In two level cache first level cache minimizes cache miss ratio , second level minimizes cache hit ratio . Explain .

in cache performace i have confusion about where to use which formula likefor write through whether use H (tc) + (1-H) (tc+m) or H (tc) + (1-H) (m)and how to identify wh...
