WebMar 24, 2024 · There are several cache mapping techniques used in computer architecture, including: Direct Mapping: In direct mapping, each cache block is assigned to a specific main memory block. For example, if the cache is 16 blocks and the main memory is 64 blocks, each cache block would be assigned to a specific block in main memory … WebDirect mapping: The simplest technique is direct mapping. It maps each block of main memory to only one possible cache line. Or, in direct mapping, allocate each memory block to a specific line in the cache. If a storage block previously occupied a row when a new block needs to be loaded, the old block will be discarded.
