Computer Architecture 1E

Course Description

This course gives basic understanding of processor architecture and computer system organization. Principles are explained using ARM CPU architecture. Internal architecture of a processor is explained together with the details of the instruction execution. Assembly language programming is explained. Interfacing with memory and IO units is explained.

Learning Outcomes

  1. list the main parts of processors and computers
  2. explain how processors execute instructions
  3. explain the function of the main parts of a processor
  4. solve simple programming problems in assembly language
  5. explain the interfacing and communication between processor, memoy, and IO units
  6. solve simple problems of communication between processor and IO units

Forms of Teaching


Lectures are held every week (3 hours per week). Theoretical foundations of computer architecture are explained together with practical programming examples using assembly language.

Independent assignments

Students solve simple problems using assembly language programming.


Students write, debugg and execute assembly programs by using a computer architecture simulator.

Grading Method

Continuous Assessment Exam
Type Threshold Percent of Grade Threshold Percent of Grade
Laboratory Exercises 20 % 15 % 20 % 7.5 %
Quizzes 20 % 15 % 20 % 7.5 %
Mid Term Exam: Written 0 % 30 % 0 %
Final Exam: Written 0 % 40 %

All Laboratory excercises must be succesfully completed (you dont get points for that) in order to get the passing grade.
