why the miss rate is decrease as the number of blocks in cache increases ?????
Homework Answers
Cache miss is a state where the data requested for processing by a component or application is not found in the cache memory. If you increase the number of blocks in cache then there is much more space to store the data. So, More to store the data means the probability of finding the data is also more. So, the miss rate is decrease as the number of blocks in cache increases

Assume the miss rate of an instruction cache is 3% and the miss rate of the data cache is 5%. If a processor has a CPI of 2 without any memory stalls and the miss penalty is 120 cycles for all misses, determine how much faster a processor would run with a perfect cache that never missed. Assume the frequency of all loads and stores is 36%. *The size of the tag field-64- (n + m 2). ** The total...

AMAT = Time for a hit + (Miss rate x Miss penalty)
For a data cache with a 4% miss rate and a 5-cycle hit latency, calculate the average memory access time (AMAT). Assume that latency to memory and the cache miss penalty together is 100 cycles. Note: The cache must be accessed after memory returns the data.

A particular computer has a single level cache with a miss rate of 6.85%. You are required to design a second level cache that brings the global miss rate of the whole cache system to 3.98%. what would be the miss rate percent required for the second level cache?

Find a wrong description about associative cache. 1-way set associative cache is identical to the direct mapped cache Each cache block contains one valid bit and one tag regardless of the number of data blocks Fully associative cache requires all entries to be searched at once Associative cache can decrease miss rate compared to direct mapped cache

For gcc, the frequency for all loads and stores is 36%. Instruction cache miss rate is 5%. Data cache miss rate is 10%. If a machine has a CPI of 2 without memory stalls and the miss penalty is 40 cycles for all misses, how much faster is a machine with a perfect cache? increase the performance by doubling its clock rate. Since the main memory speed is unlikely to change, assume that the absolute time to handle a cache...

Consider a direct-mapped cache with 32 blocks Cache is initially empty, Block size = 16 bytes The following memory addresses (in hexadecimal) are referenced: 0x2B4, 0x2B8, 0x2BC, 0x3E8, 0x3EC,0x4F0, 0x8F4, 0x8F8, 0x8FC. Map addresses to cache blocks and indicate whether hit or miss

Assume a cache with a write-through policy, non-write allocate. Your cache has a miss rate of 5%. There is a 150 cycle miss penalty. Additionally, it takes an extra 30 cycles to do a write. Your program has a base CPI of 1, is 20% loads, and 5% stores. What will its CPI be?
