【摘要】：随着数字技术的高速发展，嵌入式系统在各个领域得到了广泛的应用。雷达显控平台作为雷达系统的重要组成部分，已经越来越多的采用高性能的嵌入式系统来设计。本文设计了一个基于嵌入式系统的雷达显控平台。基于高性能嵌入式微处理器和嵌入式实时操作系统的设计有效提高了雷达显控平台的系统性能和可靠性。硬件方面，根据雷达显控平台的特殊要求，通过分析和比较选择了PowerPCQorIQ系列的P1022DS开发系统作为显控平台的嵌入式处理器，并采用LCD作为显示设备。在操作系统方面，根据项目的实际需要，选择了嵌入式实时操作系统VxWorks作为显控平台的操作系统。在项目中利用了Workbench集成开发环境进行VxWorks下的开发，相对于传统的Tornado集成开发环境，项目管理能力更强，开发更加方便。由于显控平台显示功能开发的复杂性，本项目中利用了WindML媒体库来进行开发。但是WindML媒体库中没有P1022DS开发系统上显示控制器的设备驱动。本文研究的中心内容是P1022DS开发系统上显示控制器的设备驱动开发。本文详细介绍了项目中使用的关键技术VxWorks操作系统组件、BSP、VxWorks设备驱动开发、WindML媒体库，说明了Workbench下的设备驱动开发的流程。本文分析了P1022DS开发系统上的显示控制器硬件和显示控制器设备驱动程序设计中的关键函数实现，最后对显示控制器设备驱动程序进行了调试和测试。系统测试成功，，为显控平台的进一步性能优化和功能扩展打下坚实的基础。
[Abstract]:With the rapid development of digital technology, embedded system has been widely used in various fields. As an important part of radar system, radar display and control platform has been designed with high performance embedded system. A radar display and control platform based on embedded system is designed in this paper. The design of high performance embedded microprocessor and embedded real time operating system improves the system performance and reliability of radar display and control platform. In terms of hardware, according to the special requirements of radar display and control platform, the P1022DS development system of PowerPC QorIQ series is selected as the embedded processor of the display and control platform, and LCD is used as display device by analyzing and comparing the P1022DS development system of PowerPC QorIQ series. In terms of operating system, according to the actual needs of the project, the embedded real-time operating system VxWorks is selected as the operating system of display and control platform. In the project, the Workbench integrated development environment is used to develop VxWorks. Compared with the traditional Tornado integrated development environment, the project management ability is stronger and the development is more convenient. Because of the complexity of display function development, WindML media library is used in this project. However, there is no device driver for display controller in WindML media library. The central content of this paper is the device driver development of display controller on P1022DS development system. This paper introduces in detail the key technology used in the project, VxWorks operating system component, BSPVxWorks device driver development and WindML media library, and explains the process of device driver development under Workbench. In this paper, the hardware of display controller and the key function of device driver design in P1022DS are analyzed. Finally, the device driver of display controller is debugged and tested. The system is tested successfully, which lays a solid foundation for the further performance optimization and function expansion of the display and control platform.
