Course Objectives:

This course is an undergraduate level computer organization and architecture. We will discuss organization of modern computer systems to understand what are major components in computer systems and how they work. The goal of this course is to acquire essential knowledge about computer hardware organization and to master analytical skills to measure or predict both component-level and system-level performance. By the end of the semester, you will be able to (1) identify major components in computer systems and (2) to describe how those components work. Fields of coverage include the following issues: various evaluation methods for computer performance, assembly language programming, processor data-path design, control unit design, memory hierarchy, virtual and cache memory design and multi-processor systems.

Course Syllabus:

Course Syllabus is available here (MS WORD version).

Course Project:

Assembly programing assignments
