Remotely Controlled Real-Time DSP Applications through Customized GUIs based on LabVIEW

Abstract

Abstract-The purpose of this paper is to present an approach which could expand the features of Remote Laboratories focused on embedded Digital Signal Processing (DSP) systems. The proposed approach is based on a system which is designed and developed with LabVIEW and is called R-DSP Server. Exploiting this system, users are able to develop their own Graphical User Interfaces (GUIs), named Customized GUIs, for the remote control and validation of real-time DSP applications. These GUIs are tailored to the needs of each DSP application and can be implemented in any programming language. The rapid design of Customized GUIs using LabVIEW for the communication with the R-DSP Server is achieved utilizing an implemented set of functions, called R-DSP LabVIEW Toolkit.

Real-time DSP applications remotely controlled through customized GUIs

“…The Matlab toolkit was designed from scratch. The LabVIEW toolkit is a new release of the previous toolkit which was initially presented in [7]. These toolkits support the new functionality of both the R-DSP Server and the R-DSP Protocol.…”

“…Early versions of both the R-DSP Server and the R-DSP Protocol were proposed in [7]. The new releases which are briefly described in this section, are able to handle larger TCP/IP messages.…”

“…The R-DSP Server ( Fig.1) was designed with LabVIEW and provides users with the ability to remotely control their real-time applications based on TI (Texas Instruments) DSPs through customized GUIs [7]. Using any programming language, the users are able to design their customized GUIs which interact with the R-DSP Server through TCP/IP messages.…”

Curriculum Development of an Audio Processing Laboratory Course

“…It facilitates interactive on-line simulations of modern statistical signal and spectral analysis algorithms, filter design tools, QMF banks, and state-of-the-art vocoders. A LabVIEW based Remote DSP Laboratory is developed to carry out laboratory exercises such as Finite Impulse Response, Infinite Impulse Response digital filters and FFT as well as run any executable file developed by the user [8]. Another approach for web-based remote digital signal processing laboratory using the integrated learning methodology (ILM) suggested an approach that is based on integrating on-site and distance learning environments, using web-based communication techniques and remote monitoring of laboratory equipment [7].…”

“…Because of the increasing popularity of Web-based education and the advancements in streaming media applications, several web-based DSP Laboratory courses have been designed for distance education [4,5,6,7,8]. An internet-based signal processing laboratory that provides hands-on learning experiences in distributed learning environments has been developed in [6].…”
