【摘要】 数字信号处理(DSP)技术领域是当今半导体工业最热门的技术领域之一。近年来,大量高性能集成的DSP器件的出现,使得DSP的应用越来越广泛。为了满足社会的需求,在本科和研究生中开设了DSP原理及实验开发的教学。本课题从DSP教学和研究开发的角度出发,对TI公司的DSP芯片TMS320F2812进行了详细研究。论文给出了基于TMS320F2812的实验平台硬件设计,主要包括电源部分、存储部分、串口部分,CAN总线等部分的硬件设计。该实验系统具有极好的扩展性和灵活性,已经应用于相关科研教学和项目开发中。在TMS320F2812实验平台应用方面,本文给出了基于该实验平台的毛细管电泳仪的设计,包括软、硬件开发。硬件部分开发主要是针对毛细管电泳仪外围电路的设计。整个系统以TMS320F2812作为主控制器,完成包括高压电源、温度传感器、进样冲洗、数据采集等部分的控制和实现。在毛细管电泳仪项目的开发中,TMS320F2812的A/D转换器、事件管理器、串行通信接口等部分得到充分利用,其中A/D部分经过算法优化,误差控制在5%以内,取得了一定的实验结果。更多还原

【Abstract】 Digital signal processing (DSP) is the most popular technology in today’s semiconductor industry area. In recent years, as a large number of high-performance DSP integrated technology appearance which enable the use of DSP, particularly in the application of low-end products have become increasingly vulnerable. In order to meet the needs of the society, the principles of DSP and experimental teaching are created in the undergraduate and graduate students’ course.This thesis studies and researches TI’s DSP chip TMS320F2812 in the point of DSP education and scientific research. This thesis introduces the experimental platform hardware design based on TMS320F2812, including the power supply, the storage part, the serial interface part, CAN and other parts of the hardware design, as well as its excellent scalability, flexibility to facilitate the use of original experimental platform of TMS320 LF2407 to expand research and development project. This paper also describes the software and hardware design of capillary electrophoresis instrument based on the experimental platform and the external circuit design according to the project development. The entire system specifies TMS320F2812 as the main controller, completing the control and implementation of main parts including the completion of high voltage power supply, temperature sensor, rinse sampling and data collection.In the development of the capillary electrophoresis instrument project, the A/D converter, event management and serial communication interface of TMS320F2812 have been fully utilized and have achieved good experimental results.更多还原
