Web– All addresses in set N map to same set of the cache • Addr = N mod S • A locations available • Shares costly comparators across sets • Low address bits select set – 2 in example • High address bits are tag, used to associatively search the selected set • Extreme cases – A=1: Direct mapped cache The placement policy decides where in the cache a copy of a particular entry of main memory will go. If the placement policy is free to choose any entry in the cache to hold the copy, the cache is called fully associative. At the other extreme, if each entry in the main memory can go in just one place in the cache, the cache is direct-mapped. Many caches implement a compromise in which …
