“…To develop DSP algorithms, simulation labs use high level languages such as Matlab TM [2] and LabView TM [3], or programming languages such as C [4]. JDSP, an online JAVA object-oriented tool, developed at Arizona State University, is accessible through the use of a web browser including a rich suite of signal processing functions that facilitate interactive on-line simulations of modern statistical signal and spectral analysis algorithms [5]. On the other hand, hardware labs were developed using either fixed-point or floating-point DSP processors to support various applications, including filtering, spectrum analysis and communication applications [6][7][8][9].…”

This work focuses on enabling on-line web delivery of the real-time DSP course offered at Arizona State University (ASU). For this purpose, tools are developed so that on-line students can directly control, via the web, the actual DSP boards, hardware equipment, and software tools in the Real-Time Embedded Signal Processing (RESP) laboratory from remote locations using different networking and I/O protocols. Working online test benches are set up for remote experimentation; two online test benches are presented, one using the Freescale DSP kit, and a second one using the Texas Instruments DSP kit. To test the quality of the on-line real-time DSP delivery and remote access, online assessment was conducted; the obtained feedback reflects high satisfaction recommending the use of the online version.

“…Concept-specific and general evaluation forms have been developed to obtain an overall assessment on the computer laboratories and to collect a subjective opinion on the Java modules, respectively. Details on general evaluation are given in [Spa04]. The concept-specific forms focus on each exercise by posing questions that determine whether the student has learned a specific psychoacoustic concept.…”

This paper describes a combined curriculum and research program that aims to provide scientific and investigative experiences to undergraduate (UG) students by immersing them into Electrical Engineering communications and signal processing research. Our objective is to raise the interest of undergraduates in thesis-oriented research and hence attract them to graduate education programs or prepare them for research careers in the industry. The innovation includes the development of research modules that expose UG students to signal processing for communications (SP-COM) research. These modules are taken by students across the Electrical Engineering SP-COM curriculum. Four interrelated modules are first injected in early junior-level "Signal and systems" and "Random signal analysis" courses and then in senior-level "Digital signal processing" and "Communications systems" courses. In addition, a new senior-level elective UG course entitled "Introduction to signal processing for communications research," is being developed for Fall 2005. Evaluation and assessment procedures are in place to evaluate the modules and measure the success of our objectives.

“…Although CCS is a powerful tool, it can be difficult for first time users. We have developed an interface to enable students to load and run DSP functions on the DSK through the object oriented J-DSP software [15][16]. We have also developed a simple custom GUI in J-DSP to facilitate working with the real-time DSK hardware.…”

In this paper, we describe the development of interfaces of DSP hardware with the NSF funded Java-DSP (J-DSP) education software for use in undergraduate signals and systems and DSP classes. 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 described with details. The algorithm exposes the students to the application of the FFT in a simplified MPEG-like audio compression scheme. 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.
