In today’s computer age, the processor plays a major role. A processor is the heart of the computer. These are the days where Nano components play a major role. Hence there is a need for a processor’s size to be reduced and an effective control implementation scheme is necessary. Hence, this paper made a survey on how to implement an effective control scheme. It helps the computer architects in choosing the better control implementation scheme while designing a processor for equipment like laptops, mobile phones, Personal computers etc.
