基于DSP的信号处理系统在电子信息工程综合实践中的应用
摘要
DSP技术正迅速应用于通信、电子、计算机等各个领域。用DSP技术来改进电子信息工程实践教学具有十分重要的意义。本文从基于DSP的系统平台的构思、方案设计、硬件实现、软件开发、综合性能测试分析等五个方面，系统地阐述其研究过程。
用DSP技术来改进电子信息工程实践教学，构建一个以实时高速信号处理为核心的通用软硬件实践平台，通过对信号处理中心单元DSP的应用软件设置，来改变实践平台的处理功能，去完成要求的实践活动。本文的研究工作，考查了国内外DSP技术在教学科研领域的应用，认真分析了电子信息工程实践教学活动主要内容，结合信号信息处理的新特点，制定了系统设计的总体方案。DSP的密集运算能力能实现数字信号的实时、高速处理，而计算机强大的处理能力，方便的人机对话，使它具有灵活的软件功能、友好的操作性能。系统设计综合了它们各自的功能特点，把二者结合起来，构建电子信息工程综合实践应用平台。
本文研究的系统实现了电子信息工程实践的综合性应用。系统的结构特征使得基于它的综合实践内容具有极大灵活性和二次丌发特性，同时系统自身还可以进行硬件、软件方面的功能升级。系统的应用会给“电子信息工程综合实践”教学增添新的活力，使教与学两方面的活动都达到新的水平。
The technology of DSP is being applied to much field, such as communication technology, electronic technology, computer technology, etc. There is important significance to improve the teaching of the practice of electronic and information engineering with the technology of DSP. About applying DSP to the practice of electronic and information engineering, the paper disserts the five parts including the ideal of the system, the design of the project, the realization of the hardware, the development of the software, the test of the property.
That of improving the teaching of the practice of electronic and information engineering with the technology of DSP, is to construct a hardware and software common platform with the center of DSP to finish the requested practice through changing its processing function on the platform depending on setting application software of DSP. About the research of the paper, after referred to the application of DSP technology on the teaching field, analyzed the main contents of the practice teaching of electronic and information engineering, and syncretized the new features of signal and information processing, the whole project is designed. The denseness calculation of DSP can realize the real-time and high speed processing of digital signal. The computer is in the nature of agile software and friendly operating by its strongly processing and advantageous dialogue. The system combines the computer with DSP to construct the practice platform.
The system realizes synthetical application of electronic and information engineering. It has very strong flexibility and second-developing property. Meantime, the system can upgrade itself hardware and software. The application of the system is able to increase new activity into the practice teaching of electronic and information engineering, and to take the two parts of teaching and studying to higher level.
