The each and every thing computer system does is controlled by its own Central Processing Unit (CPU). The CPU is referred as the brains of the computer system. Sometimes it is considered as the simple central processor or Nerve Centre of the system. CPU does the calculations and operations defined by the user or by the system. It is most commonly called as the digital processor. The CPU is the most important component of a computer system which communicates with other peripherals attached to it. It not only communicates but controls and manages the components of the computer system.
CPU has three operating fields, memory unit, control unit and arithmetic and logic unit or ALU. Control unit decodes the program instructions and memory unit stores the data and instruction in it. Where the ALU is the most used field of the CPU, it performs all the arithmetic and logic operations in the CPU.
The main goal of central processing unit is to be able to know the fundamental operations across the CPU. It concentrates on applications of general registers and stack organisation to retrieve the memory in CPU, and instruction sets as well as addressing modes.
By the end of this module, students will learn about the basic operations on CPU as well as memory organisation and addressing modes. In addition to these skills students are also able to intelligently interact with information professionals about critical issues related to CPU architecture and organisation.
