Speech Coding Tools using LabVIEW:
An
educational software tool is developed for teaching speech signal coding theory
and algorithms with the National Instruments LabVIEW™ package. We choose
to use LabVIEW because of its intuitive visual interface, ability to process
real-time signals and capability to interface with DSP hardware.
The tool is based on
the National Instruments LabVIEW™ environment.

J-DSP LabVIEW Interface:
The scripting capabilities embedded in the software enable generation of
HTML code and MATLABTM scripts. A new
interface has been developed to allow students and users to move between
Java-DSP and the
National Instruments LabVIEWTM
tool. This interface is made possible using J-DSP Mathscript capabilities
and provides an effective way to utilize several functions across the two
visual programming environments.

J-DSP Collaborative
Simulations or Blackboard concept: A new
J-DSP version with software infrastructure for collaborative simulations
has been developed and is under testing. It supports the idea of two
users simultaneously operating on the same J-DSP Environment. An
in-built chat facility provides communication capabilities between the
two users. The infrastructure developed is based on Java Sockets, and
previously developed J-DSP Export Script capability etc.

Interfacing J-DSP with Texas Instruments-
DSK Boards: Interfaces of DSP hardware with the NSF funded
Java-DSP (J-DSP) education software for use in undergraduate signals and
systems and DSP classes have been recently made. The interface enables
undergraduate students to design and implement algorithms real time on
DSP hardware using the user-friendly graphical interface of J-DSP.
Simulations involving digital filters and FFTs are first established in
the object oriented J-DSP environment. Through the use of a clever
software interface, a real-time implementation of the algorithm is
activated on the TI DSP Starter Kit C6713. The real-time implementation
enables the students to examine the properties of various signal
processing algorithms using real-life signals. A simple audio
compression scheme that uses the Fast Fourier Transform (FFT) is
developed. The hardware–software interaction of J-DSP with the TI DSK is
also explained to students; an introduction to the architecture and its
peripherals is also part of the learning experience. Pre- and Post-
assessment instruments have been developed and administered. |

Interfacing J-DSP with Sensor Motes:
Distributed wireless sensor
networks (WSN) are being proposed for implementing smarter environments
for security and other applications. In this project, we present a
collection of Java interfaces for the Berkley sensor motes for use in
tracking and localization research projects. By integrating the mote
interfaces with Java-DSP we can make use of the J-DSP signal processing
functions for real-time analysis of the signals acquired from the
wireless sensors. Connectivity with the signal processing environment of
Java-DSP is seamless and allows the user to program and run sensor
signal processing algorithms from remote locations. Extensions of this
project are planned for remote control of the motes by handheld devices. |

January 2003: New functions have been developed for use in high schools and freshman
engineering courses. These functions include a block that resembles a piano and
generates MIDI tones, a DTMF block that resembles a phone and various echo
blocks for use in audio effects. Read the audio
effects manual for a complete list of J-DSP functions designed
specifically for DSP beginners.
February 2003: The latest J-DSP version (v2b1) is currently used in
ASU's EEE407 undergraduate DSP
class.
