A DSP Hardware-Based Laboratory for Signals and Systems

Abstract

Hardware-based laboratories have been successfully integrated into individual Digital Signal Processing (DSP) courses at many universities. Typically, most hardware-based DSP laboratory experiences are offered to upper-level students and focus on programming the signal processor. While this approach may be ideal for preparing motivated upper-level students for future careers in signal processing, it is not suitable for students with no prior experience in the field. To address this issue, a hardware-based signal processing laboratory, based on the Texas Instruments 6713 DSP Starter Kit (DSK), suitable for students in an introductory signals and systems course has been developed. After two semesters of implementation, results indicate that student understanding is enhanced and interest levels increase when a DSP hardwarebased laboratory is integrated into an introductory signal processing course.

Teaching multi-core DSP implementation on EVM C6678 board

“…Many such courses have already been developed for different hardware platforms, including general-purpose processors (GPPs) [1][2][3], field programmable gate arrays (FPGAs) [4,5], graphical processing units (GPUs) [6] and digital signal processors (DSPs), which are historically the first integrated circuits specially designed to solve digital signal processing tasks in real-time with low-power consumptions. The educational courses on DSP programming are described in [7][8][9][10][11]. In this paper we concentrate on multicore (DSPs).…”

Upgrading Digital Signal Processing Development Boards in an Introductory Undergraduate Signals and Systems Course

“…1 Hardware-based Digital Signal Processing (DSP) laboratories have had marked success in providing hands-on, realistic lab experiences to undergraduate students in an Electrical and Computer Engineering (ECE) curriculum. 1,2,3 The development of such laboratories for a required introductory signal processing course has demonstrated that application-based exercises illustrating the fundamental signal processing concepts using a DSP hardware platform have been well received. 2 The course studied here is typically taken by sophomore or junior level students in both the ECE and Biomedical Engineering (BME) fields.…”

“…The Voice ScramblerDescrambler laboratory uses the principles of modulation and demodulation with speech or music and includes anti-aliasing filter design. 2 Prior to the course being offered with both the Beagleboard-xM and C6713 DSK hardware, the laboratory exercises were updated and re-tested, respectively including instructions and example images to make them compatible with either platform and provide an equivalent lab experience.…”

Design and Evaluation of a Web-based Virtual Open Laboratory Teaching Assistant (VOLTA) for Circuits Laboratory

“…table-based laboratories 8 , and remote laboratories 9 . In a traditional "closed laboratory" environment, students perform the assignments following a "cook-book" lab manual and submit a written report drafted after the laboratory has been completed.…”
