Course Objectives: The purpose of the course is to introduce principles of computer organization and the basic architectural concepts. It provides an in depth understanding of basic organization, design, programming of a simple digital computer, computer arithmetic, instruction set design, micro programmed control unit, pipelining and vector processing, memory organization and I/O systems.

Course Outcomes: By the end of the course the student will be able to

  • Demonstrate an understanding of the design of the functional units of a digital computer system.
  • Relate Postulates of Boolean algebra and minimize combinational functions
  • Recognize and manipulate representations of numbers stored in digital computers
  • Build the logic families and realization of logic gates.
  • Design and analyze combinational and sequential circuits
  • Identify, compare and assess issues related to ISA, memory, control and I/O functions.
  • Recall the internal organization of computers, CPU, memory unit and Input/Outputs and the relations between its main components
  • Solve elementary problems by assembly language programming
