CMSIS标准研究

Research on CMSIS Standard

由于物联网应用的跨平台特性,使得编写移植嵌入式软件变得很困难,主流硬件平台供应商都开始寻求解决方案,由ARM公司牵头制定了CMSIS标准,用于解决基于Cortex-M处理器系列的微控制器平台软件的可移植性和可复用性问题。对CMSIS标准的特性进行了详述,以CMSIS 4.5.0版本标准为例,对其各个组件进行了详细的研究,探讨了CMSIS-RTOS API接口标准在物联网领域的适用性,并列举了典型的遵循该标准的开源物联网操作系统产品对其进行佐证。

As the cross platform feature of the Io T application makes the writing and porting of embedded software become very difficult,so the main stream silicon vendors begin to find the efficient solutions and ARM company leads the development of the CMSIS standard. It means to resolve the porting and reuse problems of the embedded software of microcontroller with cortex-M processor series based. We illustrate the features and benefits of CMSIS standard and all CMSIS components are researched with CMSIS 4. 5.0 version as an example,moreover applicability of the CMSIS-RTOS standard to the Internet of Thing are discussed. we give typical open source Io T OS conformance with CMSIS-RTOS API interface standard to verify the viewpoint. We give a summarization of the paper in the end.
