Cache Memory Design

Cache Memory

Cache is a random access memory used by the central processing unit (CPU) to reduce the average time to access memory. Cache memory stores instructions that are repeatedly required to run programs.

Direct Mapped Cache (1-way Set Associative Cache)

The simplest way to determine cache locations in which to store memory blocks. In direct mapping technique, the mapping is expressed as

i = j % m
where, 
i = Cache line number
j = Main memory block number
m = Number of lines in the cache
