DSP最小应用系统设计完整论文.doc

摘 要 DSP理论和技术是目前电子技术和IT领域中的基本工程理论与核心技术，DSP技术己经成为21世纪各种新技术的基础。因此，DSP最小应用系统的开发与设计就具有十分重要的意义。本文主要研究和解决的重要课题是研制出一个功能完备、价格低廉、技术流行、能满足学习和开发双重需求的DSP最小应用系统。 本系统以TI公司的TMS320C6713芯片为核心构建最小系统，在此基础上进行各种功能扩展，从而组建开放式系统。本文重点叙述了系统的硬件设计过程和软件实现方法。首先，详细介绍了基于TMS320C6713芯片的内部结构与外设；其次介绍了基于TMS320C6713 DSP芯片的最小应用系统硬件设计和软件设计；最后，介绍了TMS320C6713的多通道缓冲串口(McBSP)以及DSP与PC上位机在串口工作模式下实现串行通信的设计，并给出相应的硬件配置、软件流程。 本课题的研究，使得使用者在此最小应用系统上可以进行常规的DSP原理实验和技术开发工作，通过实验掌握DSP芯片的基本功能和应用，从而使DSP的学习更具有实际意义、更系统化、更易于掌握。同时，使得今后可以在此基础上，根据需要进一步增加相应的软、硬件模块，扩展其功能，构建资源更加丰富的DSP硬件开发系统。 关键词：DSP；最小系统；TMS320C6000；串行通信；McBSP ABSTRACT The theories and techniques of DSP are basic engineering theories and core techniques of electronics technique and IT field nowadays. The technique of DSP has already become the foundation of various new technical at the beginning of 21 centuries.Therefore，it has very imortant significance in developing and designing the minimum application system of DSP .To design and implement a powerful inexpensive prevalent hardware system to meet requirements of learning and research is the focus of this thesis. The system takes the TM320C6713 chip of the TI Company as the core to set up the minimum worksystem,thus sets up an open experimental platform.This paper puts the emphases on hardware design and software design of the whole system.First of all， thisaper discusses inside structure and peripherals about TMS320C6713 DSP device .Secondly，thisaper describe the hardware design and software design of the whole system . Finally ,this paper describes the communieation method between TMS320C6713 and PC when the multichannel buffered serial port (McBSP) of C6713 is set up in serial port mode. Hardware configuration and software diagram are deseribed. The research of this topic,make the learner carry on the regular DSP experiment and designment to grasp the chip’s basic function and application.Thus make the learning have more practical meaning,more systematize and more easy to master.In the future,on the
