A cache has been designed such that it has 512 lines, with each line or block containing 8 words. Identify the line number, tag, and word position for the 20- bit address 3A45616 using the direct mapping method.
Distinguish between an associative and a direct-mapped cache.
What is the layout of a true cache hierarchy?
Explain the reasons why it is so difficult to devise a suitable cache replacement technique that works for all address sequences.
The low order 4 bits of the address indicate location in the cache line and the next 4 bits indicate which line in the cache should be used and the remaining bits of the address are used as the cache tag. If the following addresses are read in this order, indicate (circle or similar) each one that would result in a cache miss. 2A1220 2A122C B14408 B14428 2A122C
Consider a 32 KB 4-way set associative cache organization with 512 B block size. The size of the physical memory is 256 KB. The number of tag bits required is
Given an 8-word, 4-way set associative cache, and the sequence of address accesses below, enter the number of misses. 22 24 22 13 13 22
To what end does an associative cache serve?
The hit rate of the memory closest to the ALU is increased from 75% to 80% in a practical cache memory hierarchy. The hit latency (or hit time) for the closest memory is 20ps, while the miss latency is 20ns. What would the expected reduction in the average memory access latency be?
