Chapter 6-Problem 12E
Given a byte-addressable memory with 256 bytes, suppose a memory dump yields the results shown below. The address of each memory cell is determined by its row and column....Memory location 0xA3 contains the hexadecimal value 58.
The system from which this memory dump was produced contains 4 blocks of cache, where each block consists of 8 bytes. Assume that the following sequence of memory addresses takes place: 0x2C, 0x6D, 0x86, 0x29, 0xA5, 0x82, 0xA7, 0x68, 0x80, 0x2B. a)How many blocks of main memory are there? b)Assuming a direct mapped cache: i.Show the format for a main memory address assuming that the system uses direct mapped cache. Specify field names and sizes. ii.What does cache look like after the 10 memory accesses have taken place? Draw the cache and show contents and tags. iii.What is the hit rate for this cache on the given sequence of memory accesses?
