【摘要】：隨著計算機技術的快速發(fā)展,計算機的重要性越發(fā)的凸顯。因此,對計算機全面合理地進行維護和檢測,顯得十分必要。但其構造及工作原理均較為復雜,且國內缺乏高質量的測試系統(tǒng),導致現(xiàn)有的計算機硬件測試診斷手段落后,對測試人員的專業(yè)要求較高。本論文結合“計算機綜合測試系統(tǒng)”項目需求,對計算機顯示器測試模塊驅動程序進行了研究,重點對驅動程序框架編寫以及驅動程序的規(guī)范化、結構化、模塊化進行研究。論文主要內容有:(1).根據(jù)項目要求進行需求分析,得到測試指標。然后根據(jù)結果進行方案的設計,主要分為兩個方面:一是測試模塊的硬件設計,由于測試指標的特殊性,需通過FPGA自行設計硬件模塊;二是測試模塊的驅動架構設計,根據(jù)分層架構的思想,將整個驅動劃分為多個層次:內核層驅動、應用層驅動。底層提供機制,上層實現(xiàn)策略,明確關系,減少依賴,實現(xiàn)高內聚、低耦合。(2).計算機顯示器測試模塊內核層驅動實現(xiàn)。PXI總線基于PCI兼容核形成,因此結合PCI規(guī)范和內核模式驅動框架KMDF,將其設計成PCI設備通用驅動,提供PCI設備訪問機制,保證其具有高重用性、高可維護性和可擴展性。(3).計算機顯示器測試模塊應用層驅動實現(xiàn),包括內核交互層和策略行為層。策略行為層主要根據(jù)計算機顯示器測試指標以及計算機顯示器測試模塊控制規(guī)范來制定對測試模塊的控制策略。內核交互層調用Win32子系統(tǒng)提供的接口向系統(tǒng)提交對設備的I/O請求。(4).計算機顯示器測試模塊驅動測試。根據(jù)各層的功能,結合不同的軟件測試方法,分別完成各層模塊的單元測試以及整體框架的綜合測試,分析并解決測試過程中出現(xiàn)的問題。經(jīng)過測試與驗證,本論文設計的計算機顯示器測試模塊驅動程序滿足了設計需求,達得了預期的效果。
[Abstract]:With the rapid development of computer technology, the importance of computer becomes more and more prominent. Therefore, it is necessary to maintain and test the computer. However, its structure and working principle are complicated, and lack of high quality test system in our country, which leads to the backwardness of the existing computer hardware testing and diagnosis means, and the higher professional requirements for the testers. According to the requirement of "computer integrated test system", this paper studies the driver program of computer display test module, and focuses on the design of driver framework and the standardization, structure and modularization of driver program. The main contents of this paper are as follows: (1). According to the requirements of the project requirements analysis, get the test indicators. Then according to the results of the project design, mainly divided into two aspects: first, the hardware design of the test module, because of the particularity of the test index, we need to design the hardware module through FPGA; The second is the design of the driver architecture of the test module. According to the idea of hierarchical architecture, the whole driver is divided into several levels: kernel layer driver and application layer driver. The bottom layer provides the mechanism, the upper layer realizes the strategy, the explicit relation, reduces the dependence, realizes the high cohesion, the low coupling. (2). PXI bus is based on PCI compatible core, so it is designed into PCI device universal driver with PCI specification and kernel mode driver framework KMDF, to provide PCI device access mechanism. Ensure its high reusability, high maintainability and scalability. (3). The application layer driver of the computer display test module is implemented, including the kernel interaction layer and the policy behavior layer. The policy behavior layer mainly formulates the control strategy of the test module according to the test index of the computer display and the control specification of the test module of the computer display. The kernel interaction layer invokes the interface provided by the Win32 subsystem to submit the I / O request to the system. (4). The computer monitor test module drives the test. According to the function of each layer and the different software testing methods, the unit test of each layer module and the comprehensive test of the whole frame are completed, and the problems in the testing process are analyzed and solved. After testing and verification, the driver of the computer display test module designed in this paper meets the design requirements and achieves the desired results.
