Direct mapped cache memory complete hardware circuit.
In order to understand direct- mapped cache we will need to first partition main memory into an array where rows are called GROUP’s and columns are called TAG’s. Then we can place each group into a fixed cache line. This technique of placing a group of main memory locations into a fixed cache line is termed as Direct- mapped Cache.
The partition of main memory for direct mapped cache implementation is discussed below.
