Explain the reasons why it is so difficult to devise a suitable cache replacement technique that works for all address sequences.

Could you help me understand the basic building blocks and workings of a cache hierarchy?

A byte offset of 2 in an address means that each set in a multiway set associative (or in the directly mapped) cache has 4 bytes per set, per cache line. Keeping this in mind, answer the questions given the following details. A cache is organized as a 4 way set associative cache Each set's cache line consists of 4 words (meaning there are 16 bytes per line, for each set of the cache). Each set individually has one Valid bit, and one Dirty bit, for each line. The tag field of this cache is 8 bits wide. The address is 32 bits wide. Question 1g) If we have a write through cache coherency policy, will either of the above organizations make a difference in the amount of power used to do one write through operation (specifically above this cache layer, in the upper level memory structures to maintain coherency.

Fill in blank Suppose that linear page table is used where the memory addresses are 12-bit binary numbers and the page size is 256 bytes. If a virtual address in binary format is 101000011100, then the VPN (virtual page number) in binary format will be ---------

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

Suppose a computer using fully associative cache has 224 words of main memory and a cache of 512 blocks, where each cache block contains 16 words. How many blocks of main memory are there? What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag and offset fields? To which cache block will the memory reference 17042416 map?

How do "spatial locality" and "temporal locality" influence cache performance?
