【摘要】：計算機的系統(tǒng)分別有各個部件組成：主板、背板、外插卡、處理器、內(nèi)存、硬盤等最為重要。而其中的主板和背板作為最基礎(chǔ)性的板卡部件,起到把其他部件組合在一起的作用。 Intel公司在2011年推出了基于Sandy Bridge處理器和C600芯片組為主體架構(gòu)的Romley平臺,該平臺的芯片工藝制程達到22nm,處理器更是達到了135W高功耗高運算能力、同時滿足24跟內(nèi)存的擴展需求。 本文結(jié)合新平臺技術(shù)的升級,并同時結(jié)合產(chǎn)品在市場的定位需求,我們有針對性的開發(fā)了一個Romley平臺的X86主板。 該主板的核心是使用2顆Sandy Bridge EP處理器,支持24個DIMM,并同時支持DIMM報警管理、BMC管理、PCIe全長全高擴展、4網(wǎng)口應(yīng)用等眾多特性。 1)本文首先對X86系統(tǒng)中所實現(xiàn)的功能和硬件方案做了梳理,對于設(shè)計中的軟硬件接口做了充分的定義,在各個功能和硬件設(shè)計方案中,分析制定出了包含處理單元、管理單元、時序控制單元、網(wǎng)絡(luò)單元、存儲單元等具體細節(jié),同時明確了設(shè)計的方向 2)在接下來的一章中介紹了X86核心功能的處理器和內(nèi)存的設(shè)計原理和思路,介紹了處理器和內(nèi)存的相關(guān)技術(shù)參數(shù)、設(shè)計難點、設(shè)計調(diào)試過程中出現(xiàn)的問題 3)在該章中介紹了系統(tǒng)管理的應(yīng)用和設(shè)計思路,在系統(tǒng)的高級管理特性中,突出體現(xiàn)了部件報警、事件告警、日志報警、日志存儲等相關(guān)功能,同時對于報警功能的軟件方面做了大量的工作,通過調(diào)試、總結(jié)、再設(shè)計的循環(huán)方式,完善系統(tǒng)管理的特性。 4)接下來介紹了系統(tǒng)時序控制的原理,時序的關(guān)系、CPLD的軟件代碼,從軟件的角度完成系統(tǒng)的時序控制功能 5)接下來介紹完成了網(wǎng)絡(luò)功能的應(yīng)用和存儲模塊的設(shè)計,并從網(wǎng)絡(luò)功能的選取、網(wǎng)絡(luò)選擇的優(yōu)缺點、網(wǎng)絡(luò)的應(yīng)用范圍幾個方面做了細致的分析。 6)論文最后論文對于該主板的研究的內(nèi)容進行了總結(jié)。提煉出了該板卡設(shè)計中的設(shè)計精華和思路,并對該產(chǎn)品在服務(wù)器市場中的應(yīng)用前景做了展望和預(yù)期。
[Abstract]:Computer systems are composed of various components: motherboard, backplane, external card, processor, memory, hard disk, etc. The motherboard and backboard as the most basic card components, play the role of other components together. Intel introduced a Romley platform based on Sandy Bridge processor and C600 chipset in 2011. The chip process of the platform reaches 22nm, and the processor achieves 135W high power consumption and high computing capacity. Combined with the upgrade of the new platform technology and the positioning requirements of the product in the market, we have developed a Romley platform X86 motherboard. The core of this main board is to use 2 Sandy Bridge EP processors to support 24 DIMM, and to support DIMM alarm management. The main contents are as follows: 1) this paper firstly combs the function and hardware scheme of X86 system, and defines the hardware and software interface in the design. In each function and hardware design scheme, it analyzes and formulates the processing unit and management unit. Timing control unit, network unit, memory unit and other specific details, at the same time clear design direction 2) in the following chapter introduced the X86 core function of the processor and memory design principles and ideas. This paper introduces the related technical parameters of processor and memory, the design difficulties, the problems in the process of design and debugging. 3) in this chapter, the application and design ideas of system management are introduced, and the advanced management characteristics of the system are introduced. It highlights the related functions such as component alarm, event alarm, log storage and so on. At the same time, it has done a lot of work on the software aspect of the alarm function. Through debugging, summing up and redesigning the circulation mode, Improve the characteristics of system management. 4) introduce the principle of system timing control, the relation of time sequence and the software code of CPLD, and finish the timing control function of the system from the point of view of software 5) then introduce the application of network function and the design of storage module. The selection of network function, the advantages and disadvantages of network selection, and the application range of network are analyzed in detail. 6) the research content of the main board is summarized in the last part of the paper. This paper abstracts the essence and thinking of the design of the card, and forecasts the application prospect of the product in the server market.
