DSp in heterogeneous multicore embedded systems - A laboratory experiment

Undergraduate engineering students who are learning Digital Signal Processing (DSP) are expected to have the ability to implement their theoretical knowledge in various applications soon after graduation. In this paper, we present a laboratory experiment developed for undergraduate students that addresses the challenge of getting them familiar with implementing DSP algorithms in heterogeneous multicore systems. In a top-down approach, the students first gain control of the development environment, and then implement DSP algorithms on a general purpose and on a digital signal processor core. Through the experiment, they get to appreciate the advantages of DSP core architecture in performing signal processing algorithms, and learn methods for timing and data transfer between cores while meeting real-time constraints. In a limited time frame, this hands-on laboratory experiment exposes the students to state-of-the-art multicore development practices and increases their knowledge and interest in DSP and in embedded programming.
