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.

ROS学习指南ROS学习路径：了解ROS框架→ROSwiki初级教程→ROS-BYEXAMPLE→两种语言包（rosgpp和rospy本指南只包含前两个学习路径（了解ROS框架和ROs wiki初级教程）1了解ROS框架主要是下面这个图：概念：ROS universe全球范围的代码。我们也可以成为其中的一员Repository：每一员提供的代码库。Stack：堆，提供一个完整的功能，比如ROS BY-EXAMPLE里面的rbx1是stack.里面包含很多Package（包）。如何看出来stack呢？在这个stack里面存在stack.xml文件，这个stack.xml提供stack元数据，包括它的许可信息和stack之间的依赖关系Package：包（应用程序代码的组织单元），比如rbx1里面的rbxl-apps.rbx1-bringup等都是package，包里面有节点（node），ROs依赖库（Libraries）数据套、配置文件、第三方软件、或者任何其他逻辑构成。如何看出package？在这个package里面存在manifest.aml，这个manifest.aml提供package元数据，包括它的许可信息和package之间依赖关系，以及语言特性信息.

PrefaceDuring the past years, there has been a quickly rising interest in radio access technologies for providingmobile as well as nomadic and fixed services for voice, video, and data. The difference indesign, implementation, and use between telecom and datacom technologies is also becoming moreblurred. One example is cellular technologies from the telecom world being used for broadband dataand wireless LAN from the datacom world being used for voice-over IP.Today, the most widespread radio access technology for mobile communication is digital cellular,with the number of users passing 5 billion by 2010, which is more than half of the world’s population.It has emerged from early deployments of an expensive voice service for a few car-borne users,to today’s widespread use of mobile-communication devices that provide a range of mobile servicesand often include camera, MP3 player, and PDA functions. With this widespread use and increasinginterest in mobile communication, a continuing evolution ahead is foreseen.This book describes LTE, developed in 3GPP (Third Generation Partnership Project) and providingtrue 4G broadband mobile access, starting from the first version in release 8 and through the continuingevolution to release 10, the latest version of LTE. Release 10, also known as LTE-Advanced,is of particular interest as it is the major technology approved by the ITU as fulfilling the IMTAdvancedrequirements. The description in this book is based on LTE release 10 and thus provides acomplete description of the LTE-Advanced radio access from the bottom up.Chapter 1 gives the background to LTE and its evolution, looking also at the different standardsbodies and organizations involved in the process of defining 4G. It also gives a discussion of the reasonsand driving forces behind the evolution.Chapters 2–6 provide a deeper insight into some of the technologies that are part of LTE and itsevolution. Because of its generic nature, these chapters can be used as a background not only for LTEas described in this book, but also for readers who want to understand the technology behind othersystems, such as WCDMA/HSPA, WiMAX, and CDMA2000.Chapters 7–17 constitute the main part of the book. As a start, an introductory technical overviewof LTE is given, where the most important technology components are introduced based onthe generic technologies described in previous chapters. The following chapters provide a detaileddescription of the protocol structure, the downlink and uplink transmission schemes, and the associatedmechanisms for scheduling, retransmission and interference handling. Broadcast operation andrelaying are also described. This is followed by a discussion of the spectrum flexibility and the associated
