Where is cache memory on any Windows-based PC that has been bought in the past 10 years?
Homework Answers
In computers, the cache memory is stored between the processor and DRAM; this is called Level 2 cache. On the other hand, Level 1 cache is internal memory caches which are stored directly on the processor.

Suppose a computer has 216 words of main memory, and a cache of 64 blocks, where each cache block contains 32 words. Please explain step by step. a) If this cache is a direct-mapped cache, what is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag and word fields? b) To which cache block will the memory reference F8C9 map? c) If this cache is fully associative, what is the...

Suppose a computer using fully-associative cache has 222 words of main memory and a cache of 32 blocks, where each cache block contains 16 bytes. How many blocks of main memory are there? Assuming memory addressing starts from zero, what is the highest memory address? How many bits are needed to represent all of the memory addresses? What is the format of a memory address as seen by the cache, that is, what are the sizes of the tag and...

Suppose a computer using direct mapped cache has 232 byte of byte-addressable main memory, and a cache of 1024 blocks, where each cache block contains 32 bytes. a. How many blocks of main memory are there? b. What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag, block, and offset fields? c.To which cache block will the memory address 0x000063FA map?

32 bytes of memory. 16 bytes of 2-way setassociative cache, where blocks can go anywhere within the set. Block is 4 bytes, set in cache is two blocks. Populate memory starting with 0-9, then upper case letters. Hint- with full associativity in the set: each block has its own set of Tag bits in the cache. Memory is not organized by sets, though blocks get assigned to sets, and load in the cache per set. A) Complete: Bits in Address...

Module 10 Assignment - Direct-mapped Cache Direct-Mapped Cache In this question you're given a 16-byte memory segment and an 8-byte cache. Given the following series of memory accesses, complete the table below. Use the first Contents/Tag column to insert an item to the cache the first time and use the second Contents/Tag column if a cache entry is overwritten. Note: no index will have more than two blocks mapped to it. The first two examples have been provided. How many...

QUESTION 2 Suppose a computer using direct mapped cache has 216 bytes of byte-addressable main memory and a cache of 64 blocks, where each cache block contains 32 bytes. a. How many blocks of main memory are there? b) What is the format of a memory address as seen by the cache, (include field names and their sizes) c) To which cache block will the memory address (F8C916 map? What address in that block does it map to?

Operating Systems Questions (Please help if you can) 1. A computer has cache, main memory, and a disk used for virtual memory. If a referenced word is in the cache, 20ns are required to access it. If it is in main memory but not in the cache, 60ns are required to load it into the cache (this includes the time to originally check the cache), and then, the reference is started again. If the word is not in main memory,...
