USING J-DSP AND LABVIEW TO PERFORM UNDERGRADUATE LABS

1. Introduction

Java-DSP (J-DSP) is a universally accessible online tool primarily intended for studying concepts in signal processing1. Extensions to communications2, image processing3, speech processing4, and controls5 have also been previously produced under an NSF EMD program. In addition, J-DSP modules for demos of technology to high schools have also been generated6 and interfaces to hardware for real-time DSP have been produced7. The software is currently being tested in six different universities8 including Arizona State University, University of Texas- Dallas, University of Washington-Bothell, University of Rhode Island, University of Central Florida, and the University of Cyprus. The scripting capabilities embedded in the software enable generation of HTML code9 and MATLAB scripts10.

A new interface has been developed to allow students and users to move between Java- DSP and the National Instruments LabVIEW tool. This interface is made possible using J-DSP Mathscript capabilities and provides an effective way to utilize several functionalities across both visual environments. The motivation for providing this feature is to enable students to access important LabVIEW modules and functions and particularly tap on powerful real-time capabilities of LabVIEW that allow to acquire and process real-time signals. This interface has been tested by students in the Digital Signal Processing laboratory.

2. Generating Mathscript Code from J-DSP Simulation

Mathscript is a text-based scripting language available in LabVIEW that can be executed in the Mathscript window by the LabVIEW runtime engine. A native LabVIEW function, Mathscript node, can be used as well to form and execute a program in block diagram mode. As such most or all J-DSP simulations can be translated to Mathscript code, modularly developed for block execution. Figure 1 illustrates the generation of Mathscript code for a certain J-DSP simulation. The generated code can be obtained by selecting “Export script” feature under the
