Fundamentals of Microprocessors

I.     Course Prefix/Number: ELT 231

       Course Name: Fundamentals of Microprocessors

       Credits: 3 (2 lecture; 2 lab)

II.    Prerequisite

Recommended: ELT 221

III.   Course (Catalog) Description

Course focuses on hardware and software aspects of microprocessor/microcomputer systems, the nucleus of programmed digital systems. Content includes discussion of largescale integrated devices (LSI) with associated memory and input/output components, and rapid replacement of hardwired digital logic in industrial and commercial applications, with hands-on lab sessions.

IV.   Learning Objectives

Student will learn to:

  1. Demonstrate the application, purpose, and internal structure of a microprocessor and how it differs from a microcontroller
  2. Exhibit the difference between a microprocessor and a microcontroller system emphasizing both hardwire and software components
  3. Use a microprocessors and microcontrollers to simplify hardware and logic gates
  4. Design a microcontroller system that will accomplish a specific task.
  5. Communicate effectively in a technical and non-technical environment
  6. Compile and prepare laboratory reports.

XI.   Other Course Information

Attendance and participation is recommended.  No late assignments  will be accepted.  The homework is due on the following session.  A make-up text may be given on the following session if the student had a good excuse (working, out-of-town, sick, etc.).  If the student missed the make-up text too, then he will be awarded the best grade of the semester tests, whichever is lower.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.
