DSP Laboratory for Real-Time Systems Design and Implementation

David J. Waldo Oklahoma Christian University

Abstract

This paper describes an NSF CCLI-A&I* project at Oklahoma Christian University (OC) to develop a laboratory and three-course sequence in digital signal processing (DSP) that emphasizes the design and implementation of real-time embedded DSP systems. Real-time DSP embedded systems are becoming more pervasive throughout the engineering design industry. DSP is a major tool used in electrical engineering design solutions. Because of the increased reliance on digital systems in engineering solutions, the demands on signal processing continue to increase. It is of utmost importance that many of these systems operate in real-time. However, in most DSP curricula, the importance of real-time is not emphasized. It is the goal of this project to develop a laboratory that supports the design and implementation of real-time systems. This laboratory supports a three-course sequence in DSP with accompanying hands-on laboratories. This laboratory will also support the communications curriculum as well as the capstone design courses. Material developed for the laboratory will be distributed electronically through the internet.

I. Introduction

A shift is being made from emphasizing continuous-time linear time-invariant systems to discrete- time linear time-invariant systems1,2,3,4,5,6,7. Because of the emphasis on discrete-time systems, the use of digital signal processing (DSP) is becoming more wide spread. There are several institutions that are introducing DSP at the sophomore level3,4. Even more common are institutions that have incorporated "real-time" DSP courses. These courses usually present DSP fundamentals along with a laboratory component that uses an evaluation board that contains a DSP device8,9,10,11. Simple assembly and/or C programming techniques are used to run a system in real- time on the DSP board. Less frequent are institutions that bring real-time system design techniques to the undergraduate curriculum12.

One of the main goals of the EE Department at OC has been "to produce students who are immediately productive in industry." To achieve this goal the department has striven to have a curriculum that is not only broad but has enough depth in specialized areas to allow students to be
