CMSIS-SVD 系统视图说明

摘要：CMSIS 到底是什么？先来看看ARM公司对CMSIS的定义：ARM® Cortex™ 微控制器软件接口标准 (CMSIS) 是 Cortex-M 处理器系列的与供应商无关的硬件抽象层。CMSIS 可实现与处理器和外设之间的一致且简单的软件接口，从而简化软件的重用，缩短微控制器开发人员新手的学习过程，并缩短新设备的上市时间。软件的创建是嵌入式产品行业的一个主要成本因素。通过跨所有 Cortex-M 芯片供应商产品将软件接口标准化（尤其是在创建新项目或将现有软件迁移到新设备时），可以大大降低成本。我们知道，不同厂家，比如FSL，ST，Energy Micro等不同厂家的内核都是使用Co 阅读全文
