A computer with cache access time of 100 ns and hit ratio of 0·9 produces an average access time of ans. b)200ns d)none of these. c)190ns a)250ns one line answer

A small computer has a direct-mapped data cache of size 1 kilo Bytes. lts block size is 32 bytes, hit time is 2 processor clock cycles, and, the miss penalty is 20 processor clock cyclesWhile running a loop, in each iteration data (of size 1 byte) is accessed from memory addresses 6, 522, 768, 1028. If the loop iterates 10 times, compute the average data access time for the loop.

What is the cache hit ratio. if memory access takes 20 ns with cache and 110 ns without it (cache uses a 10 ns memory)?

If the same 1 kilo Byte cache had been organized as a two-way set associative cache (other specifications remaining the same), then what would have been the average data access time for the loop?

Assume 40% of the instructions are data accessing instruction. Let a hit take 1 clock cycle and the miss penalty is 100 clock cycle. Assume instruction miss rate is 4% and data access miss rate is 12%, what is the average memory access time?

If the average time to handle a page fault is 10 milliseconds, and a memory access requires 1 microsecond, then achieving a 99.99% hit ratio would lead to an average memory access time ofa.1 millisecondb.1.9999 millisecondsc.1.9999 microsecondsd.9.999 microseconds
