隨著科技的發展，人們在日常生活中使用的電器越來越多，電子設備的電磁兼容性（EMC）也越來越重要。所以，人們對電子設備的電磁兼容性的要求也越來越嚴格，越來越規范。而在市場競爭中，如何降低成本、減少設備體積，是各電子設備制造廠家重點研究的課題。通過對開關電源的EMI濾波電路的類別和相應的技術特點進行分析，設計出一種既能提高性能，又能降低成本的濾波電路。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.

本章參考資料《CM3 權威指南CnR2》第三章： Cortex-M3 基礎，第四章：指令集。官方暫時沒有《CM4 權威指南》，有關內核的部分暫時只能參考CM3，所幸的是CM4 跟CM3 有非常多的相似之處，資料基本一樣。還有一個資料是ARM Development Tools：這個資料主要用來查詢ARM 的匯編指令。1.1 啟動文件簡介啟動文件由匯編編寫，是系統上電復位后第一個執行的程序。主要做了以下工作：1、初始化堆棧指針SP=_initial_sp2、初始化PC 指針=Reset_Handler3、初始化中斷向量表4、配置系統時鐘5、調用C 庫函數_main 初始化用戶堆棧，從而最終調用main 函數去到C 的世界1.2 查找ARM 匯編指令在講解啟動代碼的時候，會涉及到ARM 的匯編指令和Cortex 內核的指令，有關Cortex 內核的指令我們可以參考CM3 權威指南CnR2》第四章：指令集。剩下的ARM 的匯編指令我們可以在MDK->Help->Uvision Help 中搜索到，以EQU 為例，檢索如下：
