【摘要】：隨著計算機(jī)技術(shù)的快速發(fā)展,計算機(jī)的重要性越發(fā)的凸顯。因此,對計算機(jī)全面合理地進(jìn)行維護(hù)和檢測,顯得十分必要。但其構(gòu)造及工作原理均較為復(fù)雜,且國內(nèi)缺乏高質(zhì)量的測試系統(tǒng),導(dǎo)致現(xiàn)有的計算機(jī)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(jié)合“計算機(jī)綜合測試系統(tǒng)”項目需求,對計算機(jī)顯示器測試模塊驅(qū)動程序進(jìn)行了研究,重點(diǎn)對驅(qū)動程序框架編寫以及驅(qū)動程序的規(guī)范化、結(jié)構(gòu)化、模塊化進(jìn)行研究。論文主要內(nèi)容有:(1).根據(jù)項目要求進(jìn)行需求分析,得到測試指標(biāo)。然后根據(jù)結(jié)果進(jìn)行方案的設(shè)計,主要分為兩個方面:一是測試模塊的硬件設(shè)計,由于測試指標(biāo)的特殊性,需通過FPGA自行設(shè)計硬件模塊;二是測試模塊的驅(qū)動架構(gòu)設(shè)計,根據(jù)分層架構(gòu)的思想,將整個驅(qū)動劃分為多個層次:內(nèi)核層驅(qū)動、應(yīng)用層驅(qū)動。底層提供機(jī)制,上層實現(xiàn)策略,明確關(guān)系,減少依賴,實現(xiàn)高內(nèi)聚、低耦合。(2).計算機(jī)顯示器測試模塊內(nèi)核層驅(qū)動實現(xiàn)。PXI總線基于PCI兼容核形成,因此結(jié)合PCI規(guī)范和內(nèi)核模式驅(qū)動框架KMDF,將其設(shè)計成PCI設(shè)備通用驅(qū)動,提供PCI設(shè)備訪問機(jī)制,保證其具有高重用性、高可維護(hù)性和可擴(kuò)展性。(3).計算機(jī)顯示器測試模塊應(yīng)用層驅(qū)動實現(xiàn),包括內(nèi)核交互層和策略行為層。策略行為層主要根據(jù)計算機(jī)顯示器測試指標(biāo)以及計算機(jī)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(nèi)核交互層調(diào)用Win32子系統(tǒng)提供的接口向系統(tǒng)提交對設(shè)備的I/O請求。(4).計算機(jī)顯示器測試模塊驅(qū)動測試。根據(jù)各層的功能,結(jié)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(shè)計的計算機(jī)顯示器測試模塊驅(qū)動程序滿足了設(shè)計需求,達(dá)得了預(yù)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.
