Question

Assume the following shows different parts of the address used to access a direct-mapped cache: • Byte offset: bits 0 to 7 • Index: bits 8 to 15 • Tag: bits 16-23 Assume cache is initially empty, and then the following addresses are referenced in order: AB4600 AB4604 AB4804 AC4608 AB4810 AB4604 AB461F A04804 AB461F ? miss hit miss rep hit miss hit rep hit compulsory spatial rep spatial miss hit What is the total number of misses? 7 5 What is number of compulsory misses? 7 4 What is the total number of spatial hits? 2 3 What is the total number of replacements? 2 3 What is the tag value, in hexadecimal, stored in cache block 48$_{16}$? AC A0
