随着科技的发展，人们在日常生活中使用的电器越来越多，电子设备的电磁兼容性（EMC）也越来越重要。所以，人们对电子设备的电磁兼容性的要求也越来越严格，越来越规范。而在市场竞争中，如何降低成本、减少设备体积，是各电子设备制造厂家重点研究的课题。通过对开关电源的EMI滤波电路的类别和相应的技术特点进行分析，设计出一种既能提高性能，又能降低成本的滤波电路。With the DEVELOPMENT of technology, appliances people use in their daily lives, more and more electronic devices electromagnetic compatibility （ EMC ） has become increasingly important. So, people electromagnetic compatibility requirements of electronic devices have become increasingly stringent, more and more standardized. The competition in the market, how to reduce costs, reduce equipment size, is the subject of the electronic equipment manufacturer focused on research. Through the technical characteristics of the respective category and the EMI filter circuit switching power supply is analyzed both designed to improve a performance of the filter circuit can reduce the cost.

This manual documents the Microcontroller profile of version 7 of the ARM® Architecture, the ARMv7-M architecture profile. For short definitions of all the ARMv7 profiles see About the ARMv7 architecture, and architecture profiles on page A1-20.ARMv7 is documented as a set of architecture profiles. The profiles are defined as follows: ARMv7-A The application profile for systems supporting the ARM and Thumb instruction sets, and requiring virtual address support in the memory management model. ARMv7-R The realtime profile for systems supporting the ARM and Thumb instruction sets, and requiring physical address only support in the memory management model ARMv7-M The microcontroller profile for systems supporting only the Thumb instruction set, and where overall size and deterministic operation for an implementation are more important than absolute performance. While profiles were formally introduced with the ARMv7 DEVELOPMENT, the A-profile and R-profile have implicitly existed in earlier versions, associated with the Virtual Memory System Architecture (VMSA) and Protected Memory System Architecture (PMSA) respectively.

本章参考资料《CM3 权威指南CnR2》第三章： Cortex-M3 基础，第四章：指令集。官方暂时没有《CM4 权威指南》，有关内核的部分暂时只能参考CM3，所幸的是CM4 跟CM3 有非常多的相似之处，资料基本一样。还有一个资料是ARM DEVELOPMENT Tools：这个资料主要用来查询ARM 的汇编指令。1.1 启动文件简介启动文件由汇编编写，是系统上电复位后第一个执行的程序。主要做了以下工作：1、初始化堆栈指针SP=_initial_sp2、初始化PC 指针=Reset_Handler3、初始化中断向量表4、配置系统时钟5、调用C 库函数_main 初始化用户堆栈，从而最终调用main 函数去到C 的世界1.2 查找ARM 汇编指令在讲解启动代码的时候，会涉及到ARM 的汇编指令和Cortex 内核的指令，有关Cortex 内核的指令我们可以参考CM3 权威指南CnR2》第四章：指令集。剩下的ARM 的汇编指令我们可以在MDK->Help->Uvision Help 中搜索到，以EQU 为例，检索如下：
