the CPU uses a specific mapping scheme that converts the main memory address into a cache location

The mapping scheme determines where the data is placed when it is originally copied into cache and provides a method for the CPU to find data when searching cache

Main memory and cache are both divided into the same size blocks

There are … main memory blocks than there are cache blocks

in direct mapped cache main memory blocks compete for cache locations

Number of blocks = main memory size / block size

Number of blocks = 2^n  ---- here n represents

Number of lines = cache size / line size

Number of lines = 2^n ---- here n represents

cache index, block index are essentially measured by

main memory size, cache memory size, block size are essentially measured by

main memory size is always bigger than cache memory size

in direct mapped cache index is the … significant bits in BI

in direct mapped Tag bits are the … significant bits in BI

Tag size =

Memory Size = 2 ^ n bytes --- here n represents

cache size = 2 ^ n bytes --- here n represents

block size = 2 ^ n bytes --- here n represents

TB = BI
