Experience Embedded System of mobile and consumer device Database systems Agenda Overview of Embedded Systems Embedded Java Technology and Applications IBM J9 WebSphere Everyplace Micro Environment Examples of Embedded Systems What Is an Embedded System 依據英國電機工程師協會的定義 嵌入式系統為控制、監視或輔助設備、機器或甚至工廠運作的裝置 它是一種電腦軟體與硬體的綜合體，並且特別強調『量身定做』的原則，也就是基於某一種特殊用途，我們就會針對這項用途開發出截然不同的一項系統出來，也就是所謂的客制化(Customize) 在新興的嵌入式系統產品中，常見的有手機、PDA、GPS、Set-Top-Box或是嵌入式伺服器（embedded server）及精簡型終端設備（thin client）等。 嵌入式系統應具備條件 可靠度、成本、低耗電量、微處理器、有效使用記憶體、適當的執行時間 Programming on an Embedded System No unified, no standard specification of an embedded system Processor MIPS, ARM, PowerPC, … TI, Marvel, Samsung, Broadcom, NEC, Philips, ST Micro, MTK, …. OS Nucleus, Symbian, Embedded Linux, Windows mobile, WinCE, WinRiver and more RTOS…. GUI Trolltech QT embedded, GtkFB, MicroWindow, and more proprietary GUI File systems Programming on an Embedded System 系統程式重複使用率低 系統程式工程師必須熟悉硬體架構 系統開發時間過長 系統程式與硬體架構相依性太高 使用者必須管理系統所有的硬體資源 程式語言不相通 Service vs. Embedded Systems Service vs. Embedded System “Service” is the trend to increase the value of an embedded device Open Platform is important to develop service Java Web Browsing Windows mobile/WinCE J2ME Mobile Market Today Market Trend Hike J2ME % in high-end/mid-range mobile phone market Strong momentum in mid-range/low-end mobile phone market Open standard platform for mobile service The most popular mobile game platform Google and Yahoo adopt J2ME to deploy mobile services Google map, Yahoo search, Gmail, ….. China Mobile is pushing strongly to gain high ARPU growth rate from J2ME applications since 2006 Mobile service in Europe continues to
