摘要
运动控制是数控技术的核心。DSP集高速处理能力和丰富的外设于一体,以其作为运动控
制器控制核心具有显著优势。
为简化软件开发、提高开发效率,TI公司为其DSP提供了专用实时操作系统DSP/BIOS及其
开发工具。本文通过对实时操作系统DSP/BIOS的结构与功能的分析,详细介绍了DSP/BIOS在
TMS320F2812上的移植过程。接着以实时操作系统DSP/BIOS为平台,开发了运动控制器软件系
统。论文首先针对已有的基于DSP运动控制器硬件资源,讨论了该运动控制器的基本功能和软
件设计需求。基于对运动控制器各个功能模块的实时性需求分析,规划设计了运动控制器的各
功能模块的线程优先级以及模块间的通讯方式,最终开发了基于DSP/BIOS的运动控制器软件系
统。
通过软件开发,实现了数控系统的轨迹插补、自动加工、优盘DNC加工、与PC机通信、与
手持终端通信、数据下载等实时多任务的管理与调度。最后将设计开发的软件系统脱离仿真环
境,成功应用于实际加工控制。
为验证系统性能,通过实验采集了与系统实时性相关的关键数据,据此分析了该系统的实
时性和可达的最高加工速率。进一步的比较实验表明,基于 DSP/BIOS 的运动控制器软件系统
较前后台的运动控制器软件系统具有更好的实时性能。

基于 DSP/BIOS 的运动控制器软件开发
ABSTRACT
Motion control is the core technology C systems. Since bines high-speed
processing capability and abundant peripherals, the motion-control using DSP as the core CPU
possesses,has significant advantages.
In order to simplify the software development process and to promote the development efficiency,
TI provides the specialized RTOS DSP/BIOS as well as its development tools. This paper introduces
the structure and functions of the DSP/BIOS kernel, and further introduces the detailed process of
transplanting DSP/BIOS into TMS320F2812. By analyzing the hardware of one motion controller
based on DSP, this paper discusses the foundemental functions of this motion controller. Finally, the
paper analyzes the real-time property of every single functional module in the motion-controlling
system. The research ultimately developed the software system for motion controllers based on
DSP/BIOS.
The system has achieved scheduling and managing real-time tasks such as track interpolation,
automatic processing, U-disk DNC, communication with PC, communication with handset terminal,
and data download. The software is ultimately applied essfully in actual machining control
independently from integrated development environment.
This research acquired key data relating to the system’s real-time p
