5.3.6 [15] <5.2> The formula shown on page 457 shows the typical method to index a directmapped cache, specifically (Block address) modulo (Number of blocks in the cache). Assuming a 32bit address and 1024 blocks in the cache, consider a different indexing function, specifically (Block address[31:27] XOR Block address[26:22]). Is it possible to use this to index a directmapped cache? If so, explain why and discuss any changes that might need to be made to the cache. If it is not possible, explain why. | |
