WebDirect Mapped Cache-. Direct mapped cache employs direct cache mapping technique. The line number field of the address is used to access the particular line of the cache. The tag field of the CPU address is then compared with the tag of the line. If the two tags match, a cache hit occurs and the desired word is found in the cache. WebAug 10, 2024 · 2) Associate Mapping. To overcome the problem of conflict miss in the direct mapping, we have associate mapping. A block of main memory can be mapped to any freely available cache lines. This makes fully associate mapping more flexible than direct mapping. A replacement algorithm is needed to replace a block if the cache is free.
