.Central Processing unit (CPU):

Alternately referred to as a processor, central processor, or microprocessor, the CPU is the Central Processing Unit of the computer. A computer's CPU handles all instructions it receives from hardware and software running on the computer. In terms of computing power, the CPU is the most important element of a computer system. It add and compare its data in CPU chip. A CPU or Processors of all computers, whether micro, mini or mainframe must have three element or parts primary storage, arithmetic logic unit (ALU), and control unit. Control Unit (CU) - decodes the program instruction. CPU chip used in a computer is partially made out of Silica, on other words silicon chip used for data processing are called Micro Processor. It is the brain that runs the show inside the PC. All work that is done on a computer is performed directly or indirectly by the processor. Obviously, it is one of the most important components of the Pc. It is also, scientifically, not only one of the most amazing parts of the PC, but one of the most amazing devices in the world of technology.

Major components of CPU:

In the CPU, the primary components are the ALU (Arithmetic Logic Unit) that performs mathematical, logical, and decision operations and the CU (Control Unit) that directs all of the processors operations.

This book has been written for the BE/B.Tech students of All University with latest syllabus for ECE, EEE, CSE, IT, Mechanical, Bio Medical, Bio Tech, BCA, MCA and All B.Sc Department Students.

The basic aim of this book is to provide a basic knowledge in Computer Architecture and Parallel Processing.

Computer Architecture and Parallel Processing for engineering students of degree, diploma & AMIE courses and a useful reference for these preparing for competitive examinations.

All the concepts are explained in a simple, clear and complete manner to achieve progressive learning.

This book is divided into five chapters. Each chapter is well supported with the necessary illustration practical examples and solved problems.
