Cache is a technique used to improve system's performance.
Its not an essential component. The cache memory is managed
by a cache controller. The cache system is based on the
principle of locality of reference which states that most
computer programs execute small loop of code. So the
program uses some frequent data or instruction.
Different core manufacturers use different type of
management policies for cachee.e.g. ARM use 3 policies
i. Write Policy.
2. Replacement Policy
3. Allocate policy.
But the basic principles remain almost constant.
