WebThis paper presents design of a cache controller for 4-way set associative cache memory and analyzing the performance in terms of cache hit verses miss rates. An FSM based cache controller has been designed for a 4-way set-associative cache memory of 1K byte with block size of 16 bytes. Main memory of 4K byte has been considered. Webcache as cache are too big for fully-associative mapping). • But a CAM can also be used whenever the degree of set associativity is quite high (say 16 or more) where so many shallow TAG RAMs do not make sense.

WebApr 30, 2024 · A cache is a small amount of memory which operates more quickly than main memory. Data is moved from the main memory to the cache, so that it can be accessed faster.
