Using the sequences of 32-bit memory read references, given as word addresses in the following table: 6 214 175 214 6 84 65 174 64 105 85 215 For each of these read accesses, identify the binary address, the tag, the index, and whether it experiences a hit or a miss, for each of the following cache configurations. Assume the cache is initially empty. A direct-mapped cache with 16 one-word blocks. A direct-mapped cache with two-word blocks and a total...

Here is a series of address references given as word addresses: 2, 3, 11, 16, 21, 13, 64, 48, 19, 11, 3, 22, 4, 27, 6, and 11. Using this references, show the hits and misses and the final cache contents for a two-way set-associative cache with one-word blocks and a total size of 16 words. Assume LRU replacements.

A 2-way set associative cache consists of four sets 0, 1, 2, 3. The main memory is word addressable (i.e. treat the memory as an array of words indexed by the address). It contains 2048 blocks 0 through 2047, and each block has eight words. (a) How many bits are needed to address the main memory? (b) Show how a main memory address will be translated into a tag, a set number, and an offset within a block. Illustrate this...

1. 2-way Set Associative Cache Memory Consider a hypothetical machine with 1K words of cache memory. They are in two-way set associative organization, with cache block size of 128 words, using LRU replacement algorithm. Suppose the cache hit time is 9ns, the time to transfer the first word from main memory to cache is 50ns, while subsequent words require 10ns/word. Consider the following read pattern (in blocks of 128 words, and block id starts from 0): 1 2 3 5...

Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of memory address references, given as word addresses (in decimal, the byte-offset bits have been excluded from addresses). 1, 4, 8, 5, 20, 17, 4, 56, 9, 10, 43, 5, 6, 9, 17 For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-word blocks (two words per block) and a total size of 8 blocks....
