摘要：嵌入式系統(tǒng)一般指非PC系統(tǒng)，有計算機(jī)功能但又不稱之為計算機(jī)的設(shè)備或器材。它是以應(yīng)用為中心，軟硬件可裁減的，適應(yīng)應(yīng)用系統(tǒng)對功能、可靠性、成本、體積、功耗等綜合性嚴(yán)格要求的專用計算機(jī)系統(tǒng)。簡單地說，嵌入式系統(tǒng)集系統(tǒng)的應(yīng)用軟件與硬件于一體，類似于PC中BIOS的工作方式，具有軟件代碼小、高度自動化、響應(yīng)速度快等特點(diǎn)，特別適合于要求實時和多任務(wù)的體系。嵌入式系統(tǒng)主要由嵌入式處理器、相關(guān)支撐硬件、嵌入式操作系統(tǒng)及應(yīng)用軟件系統(tǒng)等組成，它是可獨(dú)立工作的“器件”。

Abstract:Embedded systems generally refers to non-PC system,a computer function but do not call the computer equipmentorequipment.It is based on application-centric,software and hardware can be reduced,to adapt applications to the functionality,reliability,cost,volume,power consumption,demanding a comprehensive dedicated computer system.In short,embedded system set System software and hardware in one,similar to the PC in the BIOS works with the software code for small,highly automated,fast response characteristics,especially suitable for tasks that require real-time and multi-system.Embedded system consists of embedded processors,associated support hardware,embedded operating system and application software,system,etc,it can work independently of the "device."
Keywords:Embedded system;Development Status;Characteristics;Key technology
