Ⅰ.INTRODUCTION 引言With the development of puter technology, embedded system has bee an important part of the puter field . The socalled embedded system, that is . a 隨著計(jì)算機(jī)技術(shù)的發(fā)展,嵌入式系統(tǒng)已成為計(jì)算機(jī)領(lǐng)域的一個(gè)重要組成部分。嵌入式計(jì)算機(jī)中的應(yīng)用數(shù)量遠(yuǎn)遠(yuǎn)超過了各種通用計(jì)算機(jī),制造工業(yè),過程控制,通訊,設(shè)備,儀器儀表,汽車,船舶,航空,航空航天,軍事裝備,消費(fèi)類產(chǎn)品都是嵌入式計(jì)算機(jī)的應(yīng)用領(lǐng)域。一個(gè)很好的嵌入式系統(tǒng)是最小的系統(tǒng)來完成的預(yù)定目標(biāo)。system for specific applications , generally is costsensitive , and its hardware and software must be efficiently designed, tailored to remove redundancy . A good embedded system is the minimum system to plete the target functions .在一般情況下,嵌入式系統(tǒng)由硬件和軟件兩個(gè)主要部分組成,硬件部分包括處理器/微處理器,存儲(chǔ)器,外圍設(shè)備的I/O端口,圖形控制器等嵌入式系統(tǒng)。軟件部分包括操作系統(tǒng)軟件,該軟件需要實(shí)時(shí)和多任務(wù)操作,并可對(duì)應(yīng)用程序編程。B . GUI The operating system controls the application programming and hardware interaction, and the application controls the system operation and behaviors . The broad popularity is one of the major achievements of current puter technology , which greatly facilitates the use of nonprofessional users , and people no longer needs to cram a lot of mands . but can easily operate through t廣泛普及是目前的計(jì)算機(jī)技術(shù)極大地方便了非專業(yè)用戶使用的主要成就之一,人們不再需要死記硬背大量的命令,但可以很容易地通過操作窗口和菜單對(duì)計(jì)算機(jī)進(jìn)行操作。圖1是GUI系統(tǒng)的層次結(jié)構(gòu)。不同的圖形用戶界面系統(tǒng)使用不同的顯示模式。這是決定如何顯示在屏幕上的窗口,如何改變大小,如何移動(dòng)和水平的關(guān)系between the windows . It usually consists of two parts : first is the programming tool , and the second is the how to move output and read the description of the screen information . Because X window not only requires how to display 之間的窗口,它通常由兩部分組成:首先是編程工具,第二個(gè)是如何輸出和閱讀對(duì)屏幕上的信息的描述,因?yàn)閄窗口不僅要求如何顯示基本圖形對(duì)象,也提供了如何顯示窗口,所以它不僅可以是一個(gè)圖形用戶界面顯示模式,而且還可以是窗口模式 。 Ⅲ. EMBEDDED GUI SYSTEM DESIGN Ⅲ. 嵌入式GUI系統(tǒng)的設(shè)計(jì)A. System architecture Embedded GUI system uses hierarchical design, the architecture as shown in figure 2 .嵌入式GUI系統(tǒng)采用分層設(shè)計(jì),其體系結(jié)構(gòu)如圖2所示。 Core is to provide centric graphical operation functions , such as message mechanism , graphics device interface , fonts , window and desktop management capabilities . The particular partition of the centric graphical operation layer,核心是提供中心的圖形操作功能,如消息機(jī)制,圖形設(shè)備接口,字體,窗口和桌面管理功能,中心的圖形操作層的核心模塊的特定分區(qū)如圖3所示。B.
