从DSP的基本开发方法入手，介绍基于DSP的系统软/硬件开发方法，并以TMS320X281x系列处理器的各模块功能为主线详细介绍各模块的硬件使用和C语言编程。此外还根据DSP的特点介绍基于点处理器实现浮点算法的方法。在介绍功能的同时，列举了相应的应用实例，给出了硬件的原理和C语言程序清单，并标有详细的程序说明，为用户快速掌握处理器各功能单元的使用提供了方便。附光盘1张，内含C语言程序代码。-From the DSP development methodologies, this paper introduces the DSP-based hardware/software development methodology, and the main line of details each hardware module and the C programming language to TMS320X281x series processor module function. In addition, according to the characteristics of DSP floating-point arithmetic based on the point processor. Introduce the function at the same time, citing the example given hardware principles and a list of C language program, and the detailed descr iption of the procedures, provides convenience for the user to quickly master the use of the functional unit of the processor. An attached CD-ROM containing the program code of C language.
