軟硬件資源的不斷成熟和完善,使得嵌入式系統(tǒng)應(yīng)用得到了十分迅猛的發(fā)展。另一方面,互聯(lián)網(wǎng)技術(shù)的發(fā)展,使得Internet逐漸深入到人們的日常生活中。嵌入式控制網(wǎng)絡(luò)與信息網(wǎng)絡(luò)的互聯(lián)不僅拓寬了控制系統(tǒng)的控制范圍,而且豐富了信息系統(tǒng)的內(nèi)容。因此,嵌入式系統(tǒng)與Internet相結(jié)合將成為嵌入式系統(tǒng)和互聯(lián)網(wǎng)絡(luò)發(fā)展的重要方向。 現(xiàn)階段,Internet規(guī)模的日益擴(kuò)大與IPv4地址匱乏之間的矛盾越來越突出。為解決IPv4網(wǎng)絡(luò)存在的各種問題而出現(xiàn)的IPv6協(xié)議具有海量的地址空間、優(yōu)化的路由算法、自動(dòng)化的地址配置等;同時(shí)還增加了對(duì)安全性、QoS等的良好支持。因此,Internet從IPv4過渡到IPv6是一種必然的趨勢。綜上,對(duì)IPv6協(xié)議進(jìn)行研究并將其引入嵌入式系統(tǒng),實(shí)現(xiàn)嵌入式設(shè)備接入網(wǎng)絡(luò)的功能,具有較高的科研價(jià)值和現(xiàn)實(shí)意義。 本文在對(duì)嵌入式系統(tǒng)相關(guān)概念和嵌入式IPv6協(xié)議棧進(jìn)行介紹的基礎(chǔ)上,闡述了IPv6協(xié)議簇中核心協(xié)議的原理、報(bào)頭結(jié)構(gòu)和參數(shù)等。接著根據(jù)嵌入式TCP/IP協(xié)議棧的設(shè)計(jì)要點(diǎn),提出嵌入式IPv6協(xié)議棧的總體設(shè)計(jì),進(jìn)一步對(duì)協(xié)議棧的進(jìn)程模型、內(nèi)存管理、平臺(tái)無關(guān)性和通訊機(jī)制進(jìn)行了研究。然后對(duì)協(xié)議棧的裁剪和數(shù)據(jù)包的處理流程進(jìn)行分析,給出各模塊的詳細(xì)設(shè)計(jì)與實(shí)現(xiàn),主要有IPv6模塊、ICMPv6模塊、鄰居發(fā)現(xiàn)(ND)模塊和UDP模塊。最后將協(xié)議棧嵌入到uC/OS-II操作系統(tǒng)中并搭建測試環(huán)境對(duì)IPv6協(xié)議棧進(jìn)行功能性測試,結(jié)果表明協(xié)議棧功能正常,可以完成基本的通訊功能。 協(xié)議棧根據(jù)嵌入式系統(tǒng)資源有限和應(yīng)用相對(duì)單一的情況進(jìn)行裁剪,采用分層結(jié)構(gòu)實(shí)現(xiàn);同時(shí)在實(shí)現(xiàn)基本功能的前提下,為功能的擴(kuò)展提供了接口;另外,將協(xié)議棧與硬件、編譯器和操作系統(tǒng)相關(guān)的代碼獨(dú)立開來,實(shí)現(xiàn)了協(xié)議棧在不同平臺(tái)的良好移植。關(guān)鍵詞:嵌入式系統(tǒng),因特網(wǎng),ARM,IPv6,ICMPv6,鄰居發(fā)現(xiàn)協(xié)議

Abstract: Most magnetic read head data sheets do not fully specify the frequency-dependent components andare often vague when specifying other key parameters. In some cases, the specifications of two very similarheads from two different manufacturers might be quite different in terms of parameters specified and omitted.The limitations in the data sheets make designing an optimum card reading system unnecessarily difficult andtime consuming. This document outlines a strategy to overcome the above shortcomings and offers guidelinesto overcome the noise issues.

Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to allow two-point calibration of gain and offset in precision data-acquisition systems.

The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection (CMRR of 65dB at 10MHz), therebyforming an extremely versatile gain block structure thatminimizes component count in most situations. The dualinput pairs are free to take on independent common modelevels, while the two voltage differentials are summedinternally to form a net input signal.
