Modern super-fast microprocessors can process a huge amount of data in a short
duration. They need data to be processed at the same speed. Other wise they have to sit
idle and wait for the input/data, because speed of input is rather small then processing
of data. They require quick access to data to maximize their performance. If they don’t
receive the data that they require, they literally stop and wait, this results in reduced
performance and wasted power.
Current microprocessors can process an instruction in about ns (nanosecond). Time
required for fetching data from main memory (RAM) is of the order of 100 ns
