DIFFERENCE BETWEEN SINGLE-CYCLE AND MULTI CYCLE PROCESSOR

All the processors are major elements of computer architecture. Computer architecture can be defined as a specification where hardware and software technologies interconnect to form a computing platform. It refers to a system which processes any instruction fetched. There are many kinds of processors and in this paper we will discuss the various differences between single cycle and multi cycle processors. Former processors execute an instruction only in single cycle, whereas multi cycle processors disintegrates the instructions into various functional parts and then execute each part in a different clock cycle. As the multicycle processor executes every instruction by breaking it up into smaller parts the hardware used is reduced as multiple registers are introduced to hold back up the values that can be further used in execution of other instructions. Also the proposed paper defines how a multicycle processor executes instruction in smaller clock cycles then single cycle.
