Central Processing Unit (CPU) Introduction CPU also referred as microprocessor. It is a Brain as well as Heart of normal computer. It is a part of Desktop‚ Laptop or Server. It is a complete computation engine that is fabricated on a single chip. The CPU is where most calculations take place. It is the most important part of a computer system. The first microprocessor was the Intel 4004‚ introduced in 1971. It was not very powerful‚ it could do only add and subtract. It was 4 bit chip. Prior

to achieve the main function of the computer‚ which is to execute programs. Thus‚ there are four main structural elements: • Processor: Controls the operation of the computer and performs its data processing functions. When there is only one processor‚ it is often referred to as the central processing unit (CPU). • Main memory: Stores data and programs. This memory is typically volatile; that is‚ when the computer is shut down‚ the contents of the memory are lost. In contrast‚ the contents of disk

the text. 3.1 Processor-memory: Data may be transferred from processor to memory or from memory to processor. Processor-I/O: Data may be transferred to or from a peripheral device by transferring between the processor and an I/O module. Data processing: The processor may perform some arithmetic or logic operation on data. Control: An instruction may specify that the sequence of execution be altered. 3.2 Instruction address calculation (iac): Determine the address of the next instruction to
