【摘要】：摘要：伴隨著互聯(lián)網(wǎng)、網(wǎng)絡(luò)會(huì)議、視頻點(diǎn)播等電信增值業(yè)務(wù)的發(fā)展,人們漸漸地發(fā)展,傳統(tǒng)上電信行業(yè)RISC服務(wù)器獨(dú)霸天下的格局正在悄悄地發(fā)生著改變。電信行業(yè)是傳統(tǒng)的關(guān)鍵任務(wù)行業(yè),電信系統(tǒng)不僅僅每天要處理巨大的信息量,并且電信運(yùn)營(yíng)商往往需要業(yè)務(wù)系統(tǒng)7×24小時(shí)的不間斷無故障工作,對(duì)系統(tǒng)的穩(wěn)定性要求非常高。這就對(duì)構(gòu)建電信信息網(wǎng)絡(luò)系統(tǒng)的核心部件——服務(wù)器提出了很高的要求——高性能,并且高可靠,故而之前電信行業(yè)業(yè)務(wù)系統(tǒng)平臺(tái)往往采用RISC架構(gòu)服務(wù)器。近年來多核心x86服務(wù)器發(fā)展迅猛,在性能上不斷提速,幾乎與RISC相媲美,又具有可擴(kuò)展性強(qiáng)、成本低的優(yōu)點(diǎn),使x86服務(wù)器在電信行業(yè)迎來了新的機(jī)遇。中國(guó)網(wǎng)民、手機(jī)網(wǎng)民、寬帶網(wǎng)民規(guī)模的迅猛增長(zhǎng),電信運(yùn)營(yíng)商們帶來了新的挑戰(zhàn),也給x86服務(wù)器帶來了新的機(jī)會(huì)。2010年,國(guó)內(nèi)三大運(yùn)營(yíng)商,中國(guó)移動(dòng)、中國(guó)電信和聯(lián)通都加快了云計(jì)算落地的步伐,x86服務(wù)器為云計(jì)算提供了一種新的解決方案。 在以x86為代表的CISC處理器這個(gè)市場(chǎng)最大的領(lǐng)域,關(guān)于x86處理器的關(guān)鍵技術(shù)把握在少數(shù)幾家外國(guó)公司手中,國(guó)內(nèi)的研究卻非常之少,且主要集中在以工業(yè)控制和嵌入式等為市場(chǎng)的低端處理器方面,全兼容x86處理器的幾乎沒有。 項(xiàng)目以全面兼容x86為目的,設(shè)計(jì)一個(gè)x86小核,我個(gè)人的工作是對(duì)x86的中斷機(jī)制做了深入的研究,并給出實(shí)現(xiàn)方法和驗(yàn)證數(shù)據(jù)。論文的主要工作如下： 1、以x86處理器體系結(jié)構(gòu)知識(shí)為基礎(chǔ),通過intel、AMD手冊(cè)相關(guān)部分的學(xué)習(xí),理解x86CPU中斷處理的過程。以x86CPU模擬器bochs為基準(zhǔn),并查閱大量資料,對(duì)各個(gè)模式下的中斷控制轉(zhuǎn)移細(xì)節(jié)做了詳細(xì)的介紹和總結(jié)。 2、使用verilog HDL,對(duì)實(shí)模式、保護(hù)模式、虛模式、長(zhǎng)模式(IA-32e)模式下的中斷控制轉(zhuǎn)移以及中斷優(yōu)先級(jí)部分給出了RTL級(jí)設(shè)計(jì)。 3、由于時(shí)間和精力有限,論文在功能驗(yàn)證方而通過了實(shí)模式下的驗(yàn)證。即在啟動(dòng)操作系統(tǒng)的過程中,使用設(shè)計(jì)的實(shí)模式下的中斷控制轉(zhuǎn)移模塊可以使操作系統(tǒng)過度到保護(hù)模式下。保護(hù)模式下的增加了許多保護(hù)機(jī)制,如分頁(yè)、分段；使中斷處理也復(fù)雜了很多,驗(yàn)證工作進(jìn)行了一部分。對(duì)中斷優(yōu)先級(jí)部分進(jìn)行了功能仿真。
[Abstract]:Absrtact: with the development of telecom value-added services such as Internet, network conference, video on demand, people are gradually developing, and the traditional pattern of RISC server dominating the world is changing quietly.The telecommunication industry is the traditional key task industry, the telecommunication system not only has to deal with the huge amount of information every day, but also the telecommunication operator often needs the service system 7 脳 24 hours uninterrupted failure free work, the request to the system stability is very high.Therefore, the core component of the telecommunication information network system is the server, which requires high performance and high reliability. Therefore, the service system platform of telecommunication industry usually adopts RISC architecture server.In recent years, multi-core x86 servers have developed rapidly, and the performance of x86 servers has been increasing rapidly, which is almost comparable to that of RISC, and has the advantages of strong expansibility and low cost, which makes x86 servers welcome new opportunities in the telecommunication industry.With the rapid growth of Chinese netizens, mobile phone users and broadband Internet users, telecom operators have brought new challenges and new opportunities to x86 servers. In 2010, China Mobile, the country's top three operators,Both China Telecom and Unicom have stepped up the pace of cloud computing landing and x86 servers provide a new solution for cloud computing.In the market of CISC processor represented by x86, the key technology of x86 processor is held in the hands of a few foreign companies, but the domestic research is very little.And mainly focus on industrial control and embedded as the market for low-end processors, fully compatible x86 processors almost no.The purpose of the project is to fully compatible with x86 and design a small x86 core. My personal work is to do in-depth research on the interrupt mechanism of x86, and give the implementation method and verification data.The main work of the thesis is as follows:1. Based on the knowledge of x86 processor architecture, we understand the process of x86CPU interrupt processing by learning the relevant parts of Intel manual.Taking the x86CPU simulator bochs as the benchmark and consulting a lot of data, the details of interrupt control transfer in each mode are introduced and summarized in detail.2. Verilog is used to design the interrupt control transfer and interrupt priority in real mode, protection mode, virtual mode, long mode and IA-32e mode.3. Due to the limitation of time and energy, the thesis has passed the verification in the real mode.That is, in the process of starting the operating system, using the interrupt control transfer module in the real mode can make the operating system transition to the protective mode.In the protection mode, many protection mechanisms are added, such as paging and segmentation, and the interrupt processing is also complicated, and the verification is part of the work.The interrupt priority part is simulated.
