What is a memory cache-direct-mapped?

A memory cache-direct-mapped is a type of cache memory organization where each block of main memory is mapped to only one specific cache location. In this mapping scheme, the cache is divided into sets, and each set contains a fixed number of cache lines or blocks. Each block in main memory is mapped to a specific set and a specific line within that set in the cache. This mapping is done using a specific algorithm, such as modulo division or bitwise masking. When a memory access is requested, the cache controller checks if the requested block is present in the cache by comparing the memory address with the mapped cache location. If a match is found, it is a cache hit, and the data is retrieved from the cache. If there is no match, it is a cache miss, and the data is fetched from main memory and stored in the cache for future access.
