Tx_TCR.S负责中断处理程序执行完后的处理。

THREADX深入学习简介最近在做THREADX移植项目，所以在开始学习THREADX操作系统。

想把自己学到的东西总结一下。

学习操作系统时，按照领导的意思把操作系统进行模块划分。

通过查找资料将操作系统划分为任务调度模块、任务管理模块、任务间同步和通信模块、内存管理模块、中断管理模块、时钟管理模块。

下面将分别对各个模块进行分析和研究。

我将深入介绍各个模块的工作原理，通过此文档能对操作系统的工作原理有深入的了解。

首先得我的分析是针对MIPS、ARM、251内核进行分析。

我移植的平台是16位的251平台。

个人认为移植一个操作系统，首先对操作系统的内核调度原理必须十分清楚，然后对你的移植平台架构、指令集也要十分清楚，比如说下面几个方面：1、子程序调用时PC值是怎么被保存得（MPIS，将子程序的返回值存放在了RA寄存器中，251是PC自动入栈（ECALL指令）退出时使用ERET等指令，ARM是在LR寄存器中要计算相应减去的数值）。

2、中断发生时（251PC自动入栈但顺序和子程序调用压入顺序不一样，中断返回使用RETI指令。

MIPS，PC是被存入了EPC寄存器中，使用eret指令。

ARM，LR中数值的计算，赋值给PC即可）2.任务调度操作系统的核心模块就是内核调度。

首先要弄清楚其调度原理。

带着下面几个问题去思考。

1、任务入口函数第一次是怎么被执行的。

2、任务是怎么被切换的。

3、任务是怎么被抢占的。

以上几个问题是任务调度的核心。

带着这几个问题去看内核源码发现任务调度使用的方法就是任务栈和系统栈，内核利用入栈和出栈完成对任务的调度和切换。

而任务被调度起来是依靠timer驱动来工作。

基于此分析可以得出内核调度重点是以下几个方面：1、明白任务栈的构建方式，即任务创建时初始化任务堆栈时保存的数据。

这些数据要根据具体的硬件平台去实现，这个栈的初始化就是解决上面的第一个问题的。

因为在内核调度时，任务第一次被执行是出此栈来执行对应的入口函数的。

GUIDE V1.0.1an Integrated Development Environmentfor C,C++,PascalGUIDE v1.0.1用户手册一、GUIDE简介GUIDE(GAIT1 Universal IDE)是由北航GAIT研究组开发的、专门为NOI（National Olympics of Informatics）选手设计的、支持C/C++/Pascal三种程序设计语言的小型集成开发环境。

作为一个简单、快捷的开发环境，GUIDE旨在为选手们提供单文件编译、调试和运行的环境。

GUIDE主要特点如下：z跨平台：GUIDE可在linux平台和windows平台上运行，且界面和使用方法几乎完全相同；z多语言支持：GUIDE目前无差别的支持C/C++和Pascal三种语言的编辑、编译和调试运行；z单个源文件编译、调试：使用GUIDE，用户可以省去建立工程的烦琐过程，提升开发速度。

二、GUIDE的安装2.1 GUIDE (for linux)安装过程2.1.1安装GUIDE用户可以从中国计算机学会的下载页面下载GUIDE-1.0.0-linux.tar文件，使用如下命令解压缩安装文件：“tar xvf GUIDE-1.0.0-linux.tar”。

进入解压后的文件夹中，运行安装脚本install.sh。

安装脚本运行过程中，用户可以指定安装目录也可使用默认安装目录（默认安装目录/usr/bin），如下图2-1，请用户确保当前用户对指定目录有写入权限；安装脚本运行完毕之后，GUIDE安装完毕。

图2-1 GUIDE for linux安装界面2.1.2 设置GUIDE所需编译调试环境GUIDE for linux默认的C/C++和Pascal语言的编译调试工具路径为”/usr/bin”。

如果系统中编译调试工具安装在其它路径下，请参照第三章3.5.1，修改GUIDE的设置。

如果系统中尚未安装C/C++和Pascal语言的编译调试工具，请参考附录一进行安装，未完装编译调试工具或编译调试工具的路径设置不正确，将无法使用GUIDE的编译调试功能。

Lesson Ideas 84.Introduction -2Question is a tool for creating branching (binary) databases.A branching database is sometimes referred to as a binary tree or a key.Branching databases are a way of classifying a groups of objects.A branching database id a way to identify an object by answering a series of simple questions and yes/no questions.When using in class, start by doing lots of sorting and classifying activities with the children and thinking about the different ways you could sort your objects. You can use the images within the 2Question resources area of Purple Mash.There are some teaching ideas in the Lesson Ideas section of this guide.You can also fin examples branching databases in the teachers section. You can print off the image banks to go with the databases to try them out.FruitVegetablesMy friendsMusical instrumentsGetting Started -2.1Top menubarNew FileOpen a saved fileSave the current datePrint the graph and dataExport the graph and data as an imageShare the file to a displayboard or blog, create a QR code or link, set as a 2Do or send by 2Email. See the Generating Share Links Guide for more information about these features.Play: Once the table has been created it can be played to identify and object. See Playing a branching database for details2.2Main ScreenWhen you open a new file, the screen will look like this:This is the first question of the database. Click on the 'Click to Edit' box to open the editorFill in the Question Text and wording for the answer choices; this will usually be 'yes' and 'no'. You have the following additional options:Add sound from the sound picker. This includes the ability to record your own sound or upload from your device.Add an image; this could be an image of the final object or something that represents the choice made. For example, if the question was 'Does it have teeth?', the image could be some teeth. Thisadds interest to the look of the database. Images can be selected from clip-art , drawn usingthe paint tools or uploaded from your device or the device web-cam .Add additional notes; perhaps some more information about the question or the feature that the question asks about.Once you click 'OK', branches will be added to the database and you can add further questions until you are left with just one item (the end of a branch).Tick the check-box 'This is a final answer and the answer choice boxes will disappear. Put the answer into the box that says 'Question Text'.Repeat this process until all items have been classified.Add a title and Save the database, it is now ready to 'Play'.Once a database has been saved, it can be 'played' to identify an item. Click the Play button and answer each of the questions as they are presented until the answer is reached.There is a unit within the Computing Scheme of Work about Branching databases: Unit 2.4 -Questioning.This can be used with your class or adapted to children of different ages.There are example materials PDFs that can be printed and used for off-line activities.Fruits examples:How could we sort the fruits into groups?Fruits that have a skinFruits that have pipsFruits that have a stoneFruits that are roundMy friends examples:Think about the children in class, how could you sort them?Boys and girlsChildren with long hairChildren with short hairChildren with blue eyesChildren with brown eyesGuess What? Now play some games!Use the pictures of the fruit to play a game.Put the images faced up on the desk, choose a fruit (but leave the card in place).Tell the children you are going to have some fruit for lunch can they guess which fruit you have chosen.Tell the children they can ask you 1 question at a time about the fruit you have chosen but you are only allowed to answer yes or no.Lesson Ideas -Example questions:Is your fruit orange (eliminates the orange straight away!)Is your fruit long (That takes care of the banana!)Do you usually eat the skin on the fruit? (The lemon is out!)Is your usually bought as a bunch? (Possibly the grapes!)You could play similar games using images of the children.Let the children play 'Guess Who?' games with photographs of themselves or using their Purple Mash avatars. Play in small groups with images of the children on the table.Try making a fruit branching database using the example picture cards, arrows and yes/no cardsUse the 6 fruit images.Use the blank boxes to write your questions and the yes no card and arrows to display your database.Write your own questions in the blank boxes.Using yes and no answers, create a branching database with the pictures (there are some yes/no cards for you to print out too).Think about the game you have just been playing, guessing the fruit.Start with a question which will group the fruits into 2 groups. For example, is your fruit green? To make a well functioning branching database, the questions should split the remaining choices into equal groups (or as equal as possible), this means that, on average, you will get to the correct answer in the fewest steps.Use the cards to help you make your branching database on the floor.Test your branch, get a child to choose a picture of a fruit, use the questions to find out what it is.。

手把手教你移植ThreadX操作系统，基于在KeilMDK环境1. 前言本文中使用的开发板为小熊派IoT开发板，主控为STM32L431RCT6：请准备一份可以「正常使用printf串口输出的裸机工程」，本文中我使用cubemx生成。

2. 复制ThreadX源码ThreadX源码请访问开源仓库获取：https:///azure-rtos/threadx3. 添加源码到MDK工程新建threadX/common分组，添加threadX/common/src下的所有c文件：「新建threadX/ports分组，此时需要根据编译环境来选择」。

此处我们使用的是AC5编译器，则添加threadX\ports\cortex_m4\ac5\src 下的所有 .s 文件：设置使用AC5编译器：添加头文件路径：设置ASM汇编头文件路径：4. 添加并修改适配底层文件4.1. tx_initialize_low_level.sthreadX官方提供了一个底层适配文件tx_initialize_low_level.s，所在位置如图：「这里我就不得不吐槽一下了！」本来这个文件中实现了_tx_initialize_low_level()函数，该函数用于完成处理器的底层初始化，包括：•设置中断向量表•设置用于产生时钟节拍的定位器（Systick）•保存系统栈顶指针给中断程序使用•寻找RAM中首块可用地址传入tx_application_define函数供使用，也就是first_unused_memory指针的值「但是threadx在v6版本及以后，竟然想在这个文件中接管原有的处理器启动文件」，证据如下。

设置堆栈环境的证据：重新定义向量表的证据：接管复位程序的证据：作为一个用来提供调度能力的RTOS，仅仅接管pendSV中断和Systick中断就够了，甚至Systick中断还需要给HAL库用，不能直接接管走，竟然想把系统所有中断都接管了……是该说野心勃勃呢？还是该说画蛇添足呢？退一步海阔天空，把系统所有中断直接都接管了总得干点正事吧~接管中断了就写个这吐槽归吐槽，接着干活！移植threadx之后玩起来还是很舒服的！4.2. 添加适配文件将tx_initialize_low_level_sample.S 文件复制出来一份，改名为tx_initialize_low_level_bearpi.S，作为本项目的适配文件：将该文件添加到工程中：4.3. 修改适配文件① 将没有用到的标号注释，手动添加_Vectors和__initial_sp标号，分别是STM32启动文件中导出的中断向量表和栈顶指针初始值：② 设置时钟频率（80Mhz）和时钟节拍（1ms），该值用来初始化Systick定时器：③ 将设置堆栈的代码全部注释（堆栈环境已经在STM32启动文件中设置了）④ 将threadx 定义的中断向量表全部注释（使用STM32启动文件中定义的向量表）：⑤ 注释threadx定义的复位处理程序（使用STM32启动文件中的复位程序）：⑥ 修改threadx底层初始化函数：⑦ 注释用不到的函数：⑧ 处理Systick中断函数：4.4. 注释HAL库提供的中断函数去除原有stm32l4xx_it.c中的 PendSV 和 Systick 中断服务函数：至此，移植完成，编译会提示有一个错误：这个函数是留给用户自己来定义应用程序入口的，接下来会创建。

IntellItrax: auto archIve OverviewThe DBat Auto Archive functionality allows theuser to keep their database size manageable byarchiving and optimizing older jobs. It featuresthe following benefits:• Makes regular and safe backups of customerdata, which are then available for reporting.• Keeps application performance optimal bykeeping table size consistent.• Allows customers to continue using the freeMicrosoft SQL Server engine without reachingits 2 GB database size limitation, and withouthaving to upgrade to its more expensive edition.Setting up Scheduled AutO ArchiveScheduled auto archive uses SQL Server’s SQLAgentfunctionality to run a script on a regular basis tooptimize the database.auto archive functionality as soon asthe software is installed, and before anysize or performance issues may occur.Procedure1. Start DBat. Connect to a database and clickArchive. 2. Click the Auto archive old non-OK sheets and optimize databaseradio button. 3. Set the auto archive options to match the customer’s environment. • Recommendation: keep the default values for “archive sheets older than X months” and “archive every Y months”. • For the “archive start date and time,” choose a time when most downtime is available. Although the schedule auto archive can be done at the same time that users are running applications, users may experience slowdowns in this case. 4. Click Save to create the scheduled job and close the screen. Advise customers to close all running applications during the Auto Archive scheduled time. To verify the process has finished, check the “Last Archive”field on the “Auto Archive” screen.changes month to month based oncustomer work load, modify the scheduleon a monthly basis to prevent anyconflicts with running applications.IntellItrax: auto archIveMAnuAl ArchiveThe archive script can also be triggered manually, and run along with the normal scheduled archive on an as-needed basis. It can also be used instead of the scheduled process, but this is not recommended. Although the scheduled and manual archive processes are essentially the same, they do optimize sheets in different ways. The scheduled script is meant for coexistence with running applications, and therefore uses more frequent smaller transactions to commit its changes. The manual script uses one large transaction, which is more efficient, but prevents any other applications from using or changing data. This forces it to also check that it is the only ATSII database user at the beginning of the process. Procedure1. From the Auto Archive screen, click the ArchiveSheets and Optimize button.2. Choose the optimize sheets month interval. Thedefault setting is recommended.3. Make sure all users are disconnected from thedatabase, and click Yes. If any users are stillconnected, an error such as this may appear:The easiest way to disconnect other users is to restart the SQL Server service and try this operation again.4. Click OK on the prompt to acknowledge that nousers should be connected to the database whilethe archive process is running.5. The following screen is shown while the archiveprocess is running.Be advised that the archive process may take a very long time (up to several hours), depending on the size of the database. Customers should not terminate the DBat application or use other applications during this time.If the application is terminated prematurely, a long period may occur where the database cannot be used. This would happen because SQL Server would try to rollback the transaction and restore the database to the original state.6. When this prompt appears, the archive processhas finished successfully.MAnuAl Archive trOubleShOOtingIf an error occurs during the archive process, e.g. if the server runs out of disk space, SQL Server might not rollback the transaction right away because it might think the operation is still pending. The best way to force the transaction to be rolled back is to restart the SQL Server service. After this point, it may take a long time for SQL Server to restore the databaseIntellItrax: auto archIve back to a usable state. To verify the rollback processis happening, monitor the varying CPU and memoryusage of the server in Task Manager.To ensure no other users interfere with the archiveprocess, DBat locks the database exclusively to itself.If the application is terminated before the processfinishes, the database might not be usable for otherapplications even after the rollback process describedabove happens. This is because the first user toconnect to the database will lock everyone else out.In Enterprise Manager, this database state will appearlike this:To unlock the database and stop errors, restart theSQL Server service to make sure that no one else isconnected and connect to the database with DBat.Restarting SQL Server Service1. From Control Panel / Administrative tools,launch the “Services” applet.2. Find the MSSQL$ATSII service and click theRestart link.3. Select Yes to “Restart Other Services”, whichmentions the SQLAgent$ATSII servicedependency.After successfully connecting to the database, theexclusive state is cleared and other applications should be able to connect. repOrting On Archived dAtA All backups, including backups created automatically by Auto Archive, are available in the ReportingTool for reporting as part of Change Source functionality. This is the recommended way for customers to access their archived data, and is safer than the process outlined in the upcoming “Restoring Archived Data” section. Changing the data source restores the backup file into a separate database, named in a unique way based on the connected user’s computer. This allows multiple users to work with a different set of archived data from the same database server. Procedure 1. Launch ReportingTool and click the Change Source button on the main screen. 2. The “Database Selection” screen lists each database backup available to be restored. Customers can optionally use the date and time in the automatic backup filename to help them determine which backup to restore. In this example, the ATSII database is the primary database that all users are connected to. The first file below it represents a full backup made of thedatabase on 6/20/2006 at 9:38 AM. the date when a particular job was run, they can reference the scan info dialog for the remaining OK sheet in the job, which never gets archived.Other production and make ready sheets should be present in the backup at around the same creation date. 3. Select a database and click OK .
