嵌入式系统
Sign in to saveAlso known as embedded technology, embedded computing, embedded device
computer system with a dedicated function within a larger mechanical or electrical system
An embedded system is a specialized computer built into a larger device to handle one specific job—like controlling a car's engine or managing a refrigerator's temperature. These systems matter because they make everyday machines smarter and more reliable by automating tasks that would otherwise require constant human attention.

嵌入式系统(embedded system),是一种嵌入机械或电气系统内部、具有专一功能和实时计算性能的计算机系统。嵌入式系统常被用于高效控制许多常见设备,被嵌入的系统通常是包含數位硬件和机械部件的完整设备,例如汽車的防鎖死煞車系統。相反,通用计算机如个人电脑则设计灵活,可以智能處理各式各樣的運算情況,以满足广大终端用户不同的需要。 现代嵌入式系统通常是基于微控制器(如含集成内存和/或外设接口的中央处理单元)的,但在较复杂的系统中普通微处理器(使用外部存储芯片和外设接口电路)也很常见。通用型处理器、专门进行某类计算的处理器、为手持应用订制设计的处理器等,都可能应用到嵌入式系统。常见的专用处理器有数字信号处理器。 嵌入式系统的关键特性是处理特定的任务,因此工程师能对其进行优化,以降低产品的体积和成本,提升可靠性和性能。 嵌入式系统的物理形态包括便携设备如計步器、电子手表和MP3播放器,大型固定装置如交通灯、工厂控制器,大型复杂系统如混合动力汽车、磁共振成像设备、航空电子设备等。它们的复杂度低至单片机,高至大型底盘或外壳内安装有多个部件、外设和网络。
