嵌入式系统通常是以具体应用为中心，以处理器为核心且面向实际应用的软

硬件系统，其硬件是整个嵌入式系统运行的基础和平台，提供了软件运行所需的

物理平台和通信接口；而嵌入式系统的软件一般包括操作系统和应用软件，它们

是整个系统的控制核心，提供人机交互的信息等。所以，嵌入式系统的开发通常

包括硬件和软件两部分的开发，硬件部分主要包括选择合适的MCU或者 SOC

器件、存储器类型、通讯接口及I/O、电源及其他的辅助设备等；软件部分主要

涉及OS porting和应用程序的开发等，与此同时，软件中断调试和实时调试、

代码的优化、可移植性/可重用以及软件固化等也是嵌入式软件开发的关键。 -Embedded systems are generally based on the specific application as the center, the core processor and the practical application-oriented soft-
