A senior project course on applications in digital signal processing (DSP) with the TMS320 digital signal processor is described. All experiments and projects are performed using Texas Instruments' TMS320 digital signal processor. The laboratory emphasis in the senior project course reinforces the concepts of DSP covered in the lecture course. Applications in DSP are in areas such as communications, controls, speech, graphics, etc. The DSP projects presented and demonstrated by the students in the spring of 1987 are discussed. These projects can provide a guide to individuals who may incorporate a hands-on approach to DSP in courses such as senior project, senior lab, or DSP lab using the versatile TMS 320 digital signal processor 相似文献

An undergraduate level laboratory course on digital signal processors and their use in real-time digital signal processing (DSP) systems is described. Special emphasis is put on some practical issues such as execution time optimization, finite wordlength effects and a pipelined strategy as a suitable way to improve the performance of a real-time DSP system. The primary purpose of the laboratory is a better understanding of the theoretical concepts and a more active participation of the students in the course. The authors think that this paper will be of interest to those teaching related courses such as Introduction to DSP, Digital Signal Processing, Real-time DSP, Microprocessors and Hardware/Softmare Interaction. The well-known Texas Instruments' TMS320C2x and TMS320C5x fixed-point processors are used as the fundamental tool in the lab experiments and the TMS320C3x is suggested as a low-cost floating-point alternative. Enough detail is provided in the paper to duplicate certain parts of the experiments 相似文献

This paper presents a course on digital signal processing with field-programmable gate arrays (FPGA) devices. The course integrates two separate disciplines, digital signal processing (DSP) and very large scale integration (VLSI) design, and focuses on the development of a sophisticated DSP design from simulation to fixed-point implementation. The structure and methodology used in the proposed course are oriented to the design and implementation of an fast Fourier transform (FFT) spectrum analyzer. This application covers most topics included in a DSP course and gives better results that those obtained with typical courses performing independent multiple simple experiments. The project is divided into modules that show specific learning necessities and determine the course contents and organization. Each laboratory part is dedicated to design and implements the block of the analyzer related to the theoretical content presented in the class. At the end of the course the students have designed all the pieces in the DSP project and have completed and verified the system. The used methodology enables students and engineers to understand and develop complex fixed-point applications, looking for the best signal processing algorithms on hardware implementations, and also results in more motivated and active students. 相似文献

Interactive online undergraduate laboratories using J-DSP 总被引:1,自引:0,他引:1
An interactive Web-based simulation tool called Java-DSP (J-DSP) for use in digital signal processing (DSP)-related electrical engineering courses is described. J-DSP is an object-oriented simulation environment that enables students and distance learners to perform online signal processing simulations, visualize Web-based interactive demos, and perform computer laboratories from remote locations. J-DSP is accompanied by a series of hands-on laboratory exercises that complement classroom and textbook content. The laboratories cover several fundamental concepts, including z transforms, digital filter design, spectral analysis, multirate signal processing, and statistical signal processing. Online assessment instruments for the evaluation of the J-DSP software and the associated laboratory exercises have been developed. Pre/postassessment data have been collected and analyzed for each laboratory in an effort to assess the impact of the tool on student learning. 相似文献
