【摘要】:隨著數(shù)字技術(shù)的高速發(fā)展,嵌入式系統(tǒng)在各個(gè)領(lǐng)域得到了廣泛的應(yīng)用。雷達(dá)顯控平臺(tái)作為雷達(dá)系統(tǒng)的重要組成部分,已經(jīng)越來(lái)越多的采用高性能的嵌入式系統(tǒng)來(lái)設(shè)計(jì)。本文設(shè)計(jì)了一個(gè)基于嵌入式系統(tǒng)的雷達(dá)顯控平臺(tái)。基于高性能嵌入式微處理器和嵌入式實(shí)時(shí)操作系統(tǒng)的設(shè)計(jì)有效提高了雷達(dá)顯控平臺(tái)的系統(tǒng)性能和可靠性。 硬件方面,根據(jù)雷達(dá)顯控平臺(tái)的特殊要求,通過(guò)分析和比較選擇了PowerPCQorIQ系列的P1022DS開(kāi)發(fā)系統(tǒng)作為顯控平臺(tái)的嵌入式處理器,并采用LCD作為顯示設(shè)備。在操作系統(tǒng)方面,根據(jù)項(xiàng)目的實(shí)際需要,選擇了嵌入式實(shí)時(shí)操作系統(tǒng)VxWorks作為顯控平臺(tái)的操作系統(tǒng)。在項(xiàng)目中利用了Workbench集成開(kāi)發(fā)環(huán)境進(jìn)行VxWorks下的開(kāi)發(fā),相對(duì)于傳統(tǒng)的Tornado集成開(kāi)發(fā)環(huán)境,項(xiàng)目管理能力更強(qiáng),開(kāi)發(fā)更加方便。由于顯控平臺(tái)顯示功能開(kāi)發(fā)的復(fù)雜性,本項(xiàng)目中利用了WindML媒體庫(kù)來(lái)進(jìn)行開(kāi)發(fā)。但是WindML媒體庫(kù)中沒(méi)有P1022DS開(kāi)發(fā)系統(tǒng)上顯示控制器的設(shè)備驅(qū)動(dòng)。本文研究的中心內(nèi)容是P1022DS開(kāi)發(fā)系統(tǒng)上顯示控制器的設(shè)備驅(qū)動(dòng)開(kāi)發(fā)。 本文詳細(xì)介紹了項(xiàng)目中使用的關(guān)鍵技術(shù)VxWorks操作系統(tǒng)組件、BSP、VxWorks設(shè)備驅(qū)動(dòng)開(kāi)發(fā)、WindML媒體庫(kù),說(shuō)明了Workbench下的設(shè)備驅(qū)動(dòng)開(kāi)發(fā)的流程。本文分析了P1022DS開(kāi)發(fā)系統(tǒng)上的顯示控制器硬件和顯示控制器設(shè)備驅(qū)動(dòng)程序設(shè)計(jì)中的關(guān)鍵函數(shù)實(shí)現(xiàn),最后對(duì)顯示控制器設(shè)備驅(qū)動(dòng)程序進(jìn)行了調(diào)試和測(cè)試。 系統(tǒng)測(cè)試成功,,為顯控平臺(tái)的進(jìn)一步性能優(yōu)化和功能擴(kuò)展打下堅(jiān)實(shí)的基礎(chǔ)。
[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.
