Objectives of the course This course provides the basic knowledge necessary to understand the hardware operation of digital computers: It presents the various digital components used in the organization and design of digital computers. Introduces the detailed steps that a designer must go through in order to design an elementary basic computer. Presents the organization and architecture of the central processing unit. Introduces the concepts of parallel processing & pipelining Introduces the organization and architecture of input- output and memory. Summarizes the concepts of multiprocessing.

Prerequisites Students are expected to have a solid background in digital systems design. It will often be assumed that students have working knowledge of computer concepts, and binary arithmetic.
