There are three components to the course: lectures, labs. and assignments. 

The lecture is used to introduce new material; usually via a sequence of theoretical concepts, examples, and practical considerations. The book is to be used as a close adjunct to the lecture notes and examples.

The two hour weekly lab. is used for the teaching and evaluation of circuit designs using the software product LogicWorks and also the evaluation of assembly language programs implemented by the student.

Assignments include data representation, logic designs using LogicWorks, and assembly language programming.

Course Description
This course introduces the theory and practice of digital circuit design, computer architecture, and assembly language programming. Topics include number representation, Boolean algebra, expression minimization using mapping techniques, asynchronous and synchronous circuits, flip-flops, memories, arithmetic logic units, controllers, and interfacing to computers. Designs are implemented using a commercial software product. Assembly language for one or more microprocessors/microcontrollers such as the 80x86, 68HC11, or the MicroChip PICMicro is introduced, including register transfer, branching, subroutines, and interfacing.

Learning Outcomes

The student should be able to:


  1. Demonstrate an understanding of the logic blocks composing a microprocessor
  2. Appreciate, via comparisons, the architecture of microprocessors
  3. Demonstrate, by design and implementation, using a software simulator, gate level logic of microprocessor components such as memory, ALU, and controller
  4. Understand, via use, data representation including numbers of various bases and characters
  5. Design and implement assembly language programs
Means of Assessment

Evaluation will be carried out in accordance with Douglas College Policy.  The final grade will be calculated from a particular distribution from the range below.  The exact distribution will be given to the student on the first day of classes along with the course outline.


Distribution Range:


  labs. (12 to 14)                                                   15% - 30%

  assignments (4 to 6)                                           20% - 30%

  tests (1 to 2) @ 15% - 25% each                          15% - 50%

  final examination                                               20% - 40%

  class participation1                                               0% -   5%


Note #1:  participation includes (but is not limited to) attendance and/or short pop-quizzes and/or handing-in (part-of) a homework assignment
