AIM
To discuss the basic structure of a digital computer and to study in detail the organization of the Control unit, the Arithmetic and Logical unit, the Memory unit and the I/O unit.
OBJECTIVES
• To have a thorough understanding of the basic structure and operation of a digital computer.
• To discuss in detail the operation of the arithmetic unit including the algorithms & implementation of fixed-point and floating-point addition, subtraction, multiplication & division.
• To study in detail the different types of control and the concept of pipelining.
• To study the hierarchical memory system including cache memories and virtual memory.
• To study the different ways of communicating with I/O devices and standard I/O interfaces.
