If singlechip can transmit data thought this protocol , that means those electronics controlled by singlechip can connect to the Inter . This will get a series of benefits, for remote controlling, for data sharing and so on. For realizing the TCP/IP data transmission on singlechip . Need to be familiar with singlechip, familiar with TCP/IP protocol stack and Keilc programming, familiar with knowledge of electronic circuits. For researching the TCP/IP protocol and referencing the uIP protocol stack, than transplanted the uIP on singlechip. Finally pleted the puter municating to singlechip used by TCP/IP . This design is mainly on finishing the TCP/IP protocol stack, writing the driver of chip, writing application programs. This munication protocol is characteristic of less code and RAM usage, can using in the low speed requirements of the electronic. Because of taking singlechip as the carrier, this protocol shouldn39。一旦電子產(chǎn)品能入網(wǎng)，就能做到對遠(yuǎn)在千里之外的電子產(chǎn)品進(jìn)行控制。而單片機(jī)自帶的串行通信又因傳輸距離太短而阻礙其應(yīng)用范圍。Inter 采用的就是 TCP/IP 協(xié)議，網(wǎng)絡(luò)上各種各樣的計(jì)算機(jī)上只要安裝了 TCP/IP協(xié)議，它們之間就能相互通信。這里研究的TCP/IP 協(xié)議?？稍诟鞣N 8 位 CPU 上運(yùn)用。并且對數(shù)據(jù)緩存進(jìn)行壓縮，以減少對單片機(jī) RAM 的使用。例如由瑞典計(jì)算機(jī)科學(xué)學(xué)院(網(wǎng)絡(luò)嵌入式系統(tǒng)小組) 的 Adam Dunkels 開發(fā)的 uIP。還有 uC/IP(mewkip)是為為控制其設(shè)計(jì)的一個(gè) TCP/IP 協(xié)議棧。它當(dāng)前為 Linux 和 DOS 目標(biāo)而建。實(shí)現(xiàn)了 TCP、UDP、ICMP 、ARP 協(xié)議，ZLWeb 實(shí)現(xiàn)了 HTTP 協(xié)議。但目前不管國內(nèi)還是國外在單片機(jī) TCP/IP 協(xié)議的研究上，都存在以下的問題：數(shù)據(jù)傳輸速度慢，對 RAM 的使用量都大于單片機(jī)自帶 RAM。清楚理解 TCP/IP 協(xié)議在計(jì)算機(jī)網(wǎng)絡(luò)的位置和作用。對單片機(jī)結(jié)構(gòu)功能熟悉，能驅(qū)動(dòng)一般的以太網(wǎng)卡，掌握 C 編程。在實(shí)現(xiàn)計(jì)算機(jī)通過網(wǎng)絡(luò)對單片機(jī)控制的電子設(shè)備進(jìn)行監(jiān)控的功能時(shí)還要對計(jì)算機(jī)進(jìn)行相應(yīng)的配置。TCP/IP 定義了電子設(shè)備（比如計(jì)算機(jī)）如何連入因特網(wǎng)，以及數(shù)
