摘要 嵌入式系统一般指非PC系统,有计算机功能但又不称之为计算机的设备或器材。它是以应用为中心,软硬件可裁减的,适应应用系统对功能、可靠性、成本、体积、功耗等综合性严格要求的专用计算机系统。简单地说,嵌入式系统集系统的应用软件与硬件于一体,类似于PC中BIOS的工作方式,具有软件代码小、高度自动化、响应速度快等特点,特别适合于要求实时和多任务的体系。嵌入式系统主要由嵌入式处理器、相关支撑硬件、嵌入式操作系统及应用软件系统等组成,它是可独立工作的“器件”。 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 of 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 BItS 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."
