Analysis Toolkit for Code Composer Studio v2.3 User's Guide (Rev. C)
Code Composer Studio 教程(五)
百度文库专用百度文库专用Code Composer Studio 教程（五）——实时性能分析在此教程中，你对程序进行实时性能分析和恰当的时序安排。
使用RTDX（real-time data exchange ——实时数据交换）对目标进行实时改变，使用DSP/BIOS周期函数，并设置软中断优先权。
此教程需要一物理板而不能用一软件仿真器来实现。
同时，也需要CCS的DSP/BIOS和RTDX部分。
步骤1：打开并检查项目1）建立工作文件夹，编译文件，并创建下列文件：①volume.c:源文件，允许你在不停止目标程序运行的情况下使用RTDX来改变load。
②loadctrl.exe:用VB5.0编写的一个简单的窗口应用程序，它实时地用RTDX将load值送到目标。
③loadctrl.frm，loadctrl.frx，loadctrl.vbp:如果你已掌握了VB，就可以用VB来检查loadctrl.exe应用程序的这些源文件。
2）进入CCS，打开项目。
步骤2：修改配置文件在此，需加一个新的对象在配置文件中。
1）打开文件volume.cdb。
2）选择LOG_system，改变buflen特性为512 words，确定。
3）在PRD管理器上右击，选择Insert PRD。
4）将PRD0改名为loadchange_PRD。
5）在loadchange_PRD对象上右击，选择properties项。
6）将period(ticks)框中改为2，function框中改为_loadchange，确定。
①将period变默认值为2，PRD管理器用CLK管理器来驱动PRD的执行。
CLK类的。
默认特性每毫秒产生一个时钟中断来触发一个PRD标记。
因此，此PRD对象每2毫秒运行一次其函数。
②改变function为_loadchange。
每个period，此PRD对象执行一次loadchange C函数。
7）打开SWI管理器。
一个SWI对象PRD_SWI已自动加入。

Code Composer Studio 教程(三)
Code Composer Studio 教程（三）——从文件中测试算法和数据在此教程中，创建一个执行基本信号处理的程序。
在此得使用探点、图形、动画和GEL文件。
步骤1：打开并检测项目用CCS打开一个项目并检测源代码和库。
1）建立一工作文件夹，D:\han\study3。
2）在此文件夹中创建一项目，volume.mak，项目中有load.asm，vectors.asm，volume.c，RTS6201.lib，volume.h，volume.cmd等文件。
①volume.c:主程序源文件。
②volume.h:包含在volume.c中定义的常量和结构的头文件。
③Load.asm:此文件包含载入程序（一个简单的汇编循环程序，可用一条C指令调用的，其大概消耗1000条指令周期）。
④Vectors.asm:在DSP中断向量表中定义一个复位输入点。
⑤V olume.cmd:此链接命令文件映射内存块。
⑥Rts6201.lib:提供目标板的运行支持。
步骤2：观察源代码注意此例的以下部分：①在主函数输出一条信息之后，进入一无限循环。
在此循环内，其调用dataIO和处理函数。
②此处理函数将input buffer和gain的输入结果值分别相乘，输出到output buffer。
其还调用汇编载入程序，此程序在处理传递程序载入值的基础上占用指令周期。
③此例中的dataIO函数不执行任何动作，除了return之外。
除了用C代码执行I/O外，可以用一探针点来从一个主机上文件读取数据到inp_buffer位置。
步骤3：为文件I/O加一探针点（probe point）在此，加入一个探针点，从PC机上的一个文件读取数据。
Probe point对于运算法则的开发是一非常有用的工具。
可以在以下几方面使用他们：①通过运算法则，传递主机上的文件输入数据到目标的buffer以使用。
②传递目标buffer上的输出数据到主机一文件中来进行分析。

Application ReportSPRA381 – April 2002Example of GEL Usage With File I/O forCode Composer Studio v2.1 Harsh Sabikhi Code Composer Studio, Applications EngineeringABSTRACTThis application report discusses some of the functionality of the General ExtensionLanguage (GEL) that is supported by and included with Code Composer Studio™integrated development environment (IDE) v2.1. Features that will be outlined areautomated testing with GEL, workspace customization, and common Code ComposerStudio tool usage such as File I/O. In addition, the new GEL application programminginterfaces (APIs) for File I/O will be greatly exposed and used in the automation process.First, GEL will be briefly discussed and then two examples will be given to demonstratethe usefulness of the language.Requirements• Microsoft® Windows® 98, Windows 2000, Windows NT®, or Windows XP®• Code Composer Studio Version 2.1Prerequisites• Good knowledge of the C programming language• Good Knowledge of the Code Composer Studio IDE• Basic knowledge of GELCode Composer Studio is a trademark of Texas Instruments.Microsoft, Windows, Windows NT, and Windows XP are registered trademarks of Microsoft Corporation.Other trademarks are the property of their respective owners.1SPRA381ContentsIntroduction (2)1Initializing the Application (3)1.1Opening a Project Using the Board Start-Up File (3)1.2Opening a Project With a Custom Start-Up File (5)2Testing One Vector (7)2.1Verifying Files Connected to Probe Points (7)2.2Running the Application and Verifying the Results (8)3Testing Multiple Vectors (9)3.1Initializing Multiple Test Vector Case (9)3.2Verifying the Probe Points and Running the Application (10)4Callback Function (11)Conclusion (12)Appendix A.

Start-Up View for Multiple Test Vector Case (10)Figure 6. Final Output Screen of Multiple Test Vector Case (11)IntroductionPlease refer to the Example of GEL Usage With File I/O for Code Composer Studio v2.0application report (literature number SPRA774) for an introduction to GEL and a background of the procedure used for for Code Composer Studio v2.0.There have been a number of new GEL APIs added to Code Composer Studio v2.1. However, since this application note describes File I/O using GEL, only the relevant APIs will bediscussed.2Example of GEL Usage With File I/O for Code Composer Studio v2.1SPRA381 1 Initializing the ApplicationIn Code Composer Studio v2.0, there was no way of performing File I/O operations in anautomated manner without going through the graphical user interface (GUI) in the IDE. If theuser creates applications that require the testing of various test vectors, the old method canbecome very tedious and time-consuming. The File I/O GEL functions for Code ComposerStudio v2.1 have corrected this by providing basic File I/O functionality through GEL (as well as indirectly through the APIs), which can then be used in automation scripts. The new functionsinclude GEL_AddInputFile, GEL_AddOutputFile, GEL_RemoveInputFile, andGEL_RemoveOutputFile. Each of these functions can either be specified by program address or by source file name. There are two versions of these GEL functions that allow the user to bind input/output file operations to either a user-specified source file name and line number, or aprogram memory address. The following is an example of the GEL_AddInputFile andGEL_AddOutputFile in their two forms. The parameters in [ ] are optional.GEL_AddInputFile("srcFileName",lineNumber,"connectFileName",format,"startAddr"[,"length"][,page][,wraparound][,"condition"])GEL_AddInputFile(programAddr,"connectFileName",format,"dataAddr"[,"length"][,page][,wraparound][,"condition"])GEL_AddOutputFile("srcFileName",lineNumber,"connectFileName",format,"startAddr"[,"length"][,page][,"condition"])GEL_AddOutputFile(programAddr,"connectFileName",format,"dataAddr"[,"length"][,page][,"condition"])NOTE: This application note makes use of the volume1 project that comes with every CodeComposer Studio software package. For this particular application note, the volume.c file had to be altered a little to cater for the particular features of this note. Before proceeding, pleasereplace the volume.c file in the volume1 folder with the one provided in Appendix A.1.1 Opening a Project Using the Board Start-Up FileFirst, we will create a custom GEL file that will open the volume1 project, load the COFF file into memory, and connect the Probe Points—all at start-up of Code Composer Studio. This file also contains built-in GEL functions that support performing a ‘file copy’ from GEL. (This will be seen and used later to avoid overwriting user test data results, by copying the generated output data file to an another user-defined data file). The Probe Points are connected using the source line versions of GEL_AddInputFile() and GEL_AddOutputFile(). The copy is performed by the calling the built-in GEL_System() function that executes a DOS command from within the IDE. Theoutput of the DOS command is sent to an output window within the IDE, and only commandsthat display a text message and require no user interface can be executed. GEL_TextOut() isanother built-in function that is used in the volume_test.gel file. This function simply prints a text message to an output window similar to the printf function in the C programming language.Example of GEL Usage With File I/O for Code Composer Studio v2.13SPRA381Once you set up your target board through the import configuration dialog box, the GEL file will be called directly from the board setup GEL file.1. Launch Code Composer Studio2. First, the developer has to create two data files, one for input and one for output. Call theinput file indata1.dat and the output file outdata.dat, which will initially be empty. Thecontents of indata1.dat are in Appendix B. These files will be used in Section 2 andSection 3.3. Go to File → New → Source File. Create a GEL file called volume_test.gel by choosingFile → Save As. For convenience, save it under the same directory as the volume1project, which is <install path>\tutorial\<target>\volume1. The source code is provided inAppendix C. Now, exit Code Composer Studio.4. Open up the CC_Setup menu of Code Composer Studio v2.1. In the import configurationdialog box, choose your specific board and click import, and then close. If there are anyprevious targets in the system configuration, remove them.5. In the system configuration, right-click on your board, select properties, and select theStartup GEL File(s) tab. Verify the board start-up GEL file is there and note its location forfurther use. And now close the board dialog box.6. Open up Windows Explorer and browse to the location of your board’s initial GEL filefrom Step 4. Open the file using your favorite text editor. In the StartUp functioncontained within the GEL file, load the volume_test.gel file by typing in GEL_LoadGel(“<target>\\ tutorial\\<target>\\volume1 \\volume_test.gel”), save your changes to thesame location as the volume_test.gel file as in Step 3, and exit. This will prevent the userfrom altering the board-specific GEL file.7. In the file menu of the CC_Setup, choose exit and a dialog box will appear with thequestion “Save changes to system configuration?”, click yes. Now, another dialog boxappears with the question “Start Code Composer Studio on exit?”, click yes. This willlaunch Code Composer Studio with the GEL file called at start-up. Notice the featuresand verify the functionality of the automation. The volume project is loaded as well as theGEL file. Your screen should resemble the screen capture in Figure 1.4Example of GEL Usage With File I/O for Code Composer Studio v2.1SPRA381Figure 1. Start-Up View Using Board GEL File1.2 Opening a Project With a Custom Start-Up FileIf your board does not have a start-up file or you would like to create your own, then follow the steps below. Please note if the developer decides not to perform the steps in Section 1.1, Step 2 of Section 1.1 (creating the data files) still has to be completed for this section.1. Launch Code Composer Studio.2. Go to File → New → Source File. Create a GEL file called start_volume.gel by choosingFile → Save As. For convenience, save it under the same directory as the volume1project, which is <install path>\tutorial\<target>\volume1. The source code is provided inAppendix D of this document.3. Repeat Step 2 and create another GEL file called volume_test.gel. The source isprovided in Appendix C. Exit Code Composer Studio.Example of GEL Usage With File I/O for Code Composer Studio v2.15SPRA3816 Example of GEL Usage With File I/O for Code Composer Studio v2.14. Open up the CC_Setup menu of Code Composer Studio v2.1 and close the importconfiguration dialog box (unless your specific target is not already configured). If yourtarget is already in the system configuration, remove it. This will remove any previousGEL files that were loaded with the board.5. Drag and drop your board in the system configuration. Click on the processorconfiguration and add a single processor. Next, click on the Startup GEL File(s) dialog box and click on the browse button. Browse to where the start_volume.gel file is located (refer to Step 2) and click ok and then finish.6. In the file menu, choose exit and a dialog box will appear with the question “Savechanges to system configuration?”, click yes. Now, another dialog box appears with the question “Start Code Composer Studio on exit?”, click yes. This will launch CodeComposer Studio with the GEL file called at start-up. Notice the features and verify the functionality of the automation. The GEL files load the volume project as well as copyindata1 into indata.7. After Code Composer Studio starts, choose File → Load Program, and select thevolume.out file. Your screen should resemble the screen capture in Figure 2.Figure 2. Start-Up View Using Custom GEL FileSPRA381Example of GEL Usage With File I/O for Code Composer Studio v2.1 72 Testing One Vector2.1 Verifying Files Connected to Probe PointsFor the single test vector case that requires only one input and one output vector, no additional code has to be added to the GEL files because the Probe Points are already connected when Code Composer Studio is launched.1. From Section 1.1 or 1.2, when Code Composer Studio is launched, the volume project isopened. Expand the view and double-click on the volume.c file. Take a second toexamine the new source code and read the comments. Please note that in copying and pasting the new code, the line numbers may differ from the ones in Figure 3.2. To verify the connections, choose File → File I/O and notice that indata1.dat is connectedas an input file and outdata.dat is connected as an output file. In addition, if you click onthe Probe Point button, you will see a detailed version of the each connection.Figure 3. Probe Point Setup Workspace3. Now that we have successfully added the File I/O functionality to our project, let’s run theapplication and verify the results.SPRA3818 Example of GEL Usage With File I/O for Code Composer Studio v2.12.2 Running the Application and Verifying the ResultsSince this section tests only a single vector, only one output file is copied.1. Let’s make use of GEL now to copy the output file to a user-defined data file. In thevolume.c file, toggle a Probe Point on line 74 (puts(“Connecting Output File to a user defined Text File\n");). From the debug menu, choose Probe Points and highlight line 74. In the probe type field, select Probe at location if expression is TRUE, and in theexpression field, and type in Test_File1() and click Replace. Recall this is a GEL function that copies the output file to a user-defined file for testing purposes. Choose Debug → Run to run the application and watch the output screens to see the execution status. Yourscreen should resemble the screen capture in Figure 4.Figure 4. Resultant Output Screen of Single Vector Case2. Verify the results by checking all of the data files. That is, validate the contents of indata1,outdata, and outdata1. The contents of indata1 should have been probed out to outdata, and finally outdata was copied to outdata1. Since there was no transformation on the input data, the input data file should be equivalent to the output data file.SPRA381 3 Testing Multiple VectorsIn this section we will start a new workspace to accommodate for the multiple input test vectors.To test multiple vectors using GEL, we cannot have n input and n output Probe Points eachconnected to a specific GEL function. Rather we have to make use of one entry point and one exit point, since GEL is a scripting language that is asynchronous. The GEL functions that are connected to these Probe Points are dynamic—meaning they depend on a counter. The counter keeps track of the number of test vectors and provides a convenient method of parsing data. At the dataInput() function in our source code, we will connect a single input file that will contain a different input file depending on the counter value. All of the data in these files will be transferred to a single output data file that is connected via the Probe Point at the dataOutput() function.3.1 Initializing Multiple Test Vector Case1. Open up Windows Explorer and create three input data files called indata1, indata2, andindata3 that contain the integer values in Appendix B. These data files will be used asinput test vectors. If the user has followed Section 2, then indata1 should already exist.Also, we will make use of the output file outdata.dat from Section 2 but delete itscontents.2. First, we will create an input GEL file that, depending on the counter value, will loadindata2 or indata3 to be processed. In Code Composer Studio, Select File → NewSource file and copy and paste the source code provided in Appendix E. Choose File →Save As and call the file input.gel. Next, we will modify our board GEL file to preload theinput.gel and volume_test.gel on start-up of Code Composer Studio.3. Open up Windows Explorer, browse to the location of your specific board file, and open itusing any text editor. We will add GEL syntax in the start-up function to load the two GELfiles relevant to this section. Copy and paste the following lines of code in the start-upfunction.GEL_LoadGel(“c:\\ti\\tutorial\\dsk6711\\volume1\\input.gel”);GEL_LoadGel(“c:\\ti\\tutorial\\dsk6711\\volume1\\volume_test.gel”);Please note, if you performed the steps in Section 2, then the volume_test.gel file shouldalready be in you board file. Save the changes and restart Code Composer Studio with yourboard file setup (please refer to Section 1.1 for the procedure). Notice the features andfunctionality of the automation. Your screen should resemble the screen capture in Figure 5.Example of GEL Usage With File I/O for Code Composer Studio v2.19SPRA381Figure 5. Start-Up View for Multiple Test Vector Case3.2 Verifying the Probe Points and Running the Application1. Please make the appropriate changes to the source as specified in the comments onlines 73 and 74. In Code Composer Studio, open up the volume.c file, go to line 73, anduncomment the puts(“Connecting a different input file to indata.dat\n”);. Next, go to line74 and comment the puts(“Connecting an output file to a user defined data file\n”);. Now,rebuild the project.2. As previously mentioned in Section 2, in the volume_test.gel file under the start-upfunction, the new GEL APIs are used to connect Probe Points to an input and output file.Initially, indata1.dat is added to line 62 and outdata.dat is connected to line 70.3. Choose Debug → Probe Point and select line 73. In the Probe type field, choose Probeat Location if expression is TRUE; and in the expression field, type in Input_File(). ClickReplace and then ok. The Input_File() function, depending on the counter value, will firstremove the old Probe Point, connect a new one, and then restart the program from main.4. Now, we are ready to run and test the program. Choose Debug → Run. Watch youroutput screens to check the status of the test. Finally, once all of the data is inoutdata.dat, we can make use again of the GEL menu to copy the contents of outdata.datto some other data file. For illustration purposes, we copy the file to outdata1.dat. Choose 10Example of GEL Usage With File I/O for Code Composer Studio v2.1GEL → GEL_Automation → Test_File1. This GEL function was created using thehotmenu keyword and is part of the volume_test.gel file.5. Verify the results by checking the contents of the data files. The resultant output fileoutdata.dat is given in Appendix F. After rearranging, the developer’s screen shouldresemble the screen capture in Figure 6.Figure 6. Final Output Screen of Multiple Test Vector CaseFunction4 CallbackWhat makes GEL even more appealing is the fact that it supports a few callback functions.These functions are executed when a particular situation occurs on the target. Currently, there are four callback functions. The first is OnFileLoaded(), which if defined in a loaded GEL file is called after a program is loaded into memory. It takes two integer parameters: one that indicatesa success or fail, and the other to indicate if only symbols were loaded. This function has acounterpart OnPreFileLoaded() that requires no input parameters, and if defined in a loadedGEL file, it is called before a program is loaded. Another useful function is OnReset(), which is called when a target processor has been reset. It requires one input parameter to suggest if the call to this function was successful. The last callback function that GEL supports is OnRestart(), which is called when the program is restarted. This function also requires one input parameter to denote if the call to this function was successful.ConclusionA question that commonly arises is why we would want to take the time to create these GELfunctions? At first, creating these functions is time-consuming but it has long-term benefits. For example, what would happen if we did not load the start_volume.gel file or load our GEL filethrough the board start-up file? If these files were not loaded, then every time we start CodeComposer Studio, the project, along with the associated GEL file(s), would have to be loaded manually. This will, in turn, not only become time-consuming but tedious. GEL is particularlyimportant in automating some common tasks and testing the results of a project. As we have seen, given an input file(s), GEL can buffer out these n files into one output file. In addition, it can copy the resultant output file(s) to any user-defined location for further testing. Thedeveloper may want to compare the output with the expected output and generate a difference table.Throughout this report, many built-in GEL functions were used. Only those functions new for Code Composer Studio v2.1 were explained in detail. For all other functions related to thisapplication note, please refer to the Example of GEL Usage With File I/O for Code Composer Studio v2.0 application report (literature number SPRA774). For more information on otherfunctions, please refer to the online help or to the contents menu under help in Code Composer Studio.Although the application itself is quite general, the developer should definitely extend theexamples provided to fit their specific needs. Furthermore, for the multiple test vector case, only three test vectors were used. This can be extended to hundreds of test vector cases by making little changes to the GEL files.Appendix A.

You can launch CCS IDE, open a .pjt file,build the .pjt file, and download the resulting .out file to a developmentboard from a LabVIEW VI to automate CCS IDE functionality.The block diagram in Figure1 shows how you can automate the processof compiling DSP target code and embedding the code on a developmentboard. Wire the .pjt file path to the CCS Open Project VI to open the.pjt file in CCS IDE. The CCS Build VI builds the .pjt file to create theDSP target code .out file. The CCS Download Code VI downloads the.out file to the development board. The CCS Run VI runs the embedded.out file on the development board. You then can use the toolkit RTDXcommunication and the toolkit memory VIs to access data from the targetcode.Figure 1. LabVIEW Automation of CCS IDEThe CCS Halt VI and CCS Close Project VI stop the .out file running onthe development board and close the project in CCS IDE. Exchanging Data with DSP Target CodeAfter you create DSP target code in the CCS IDE and embed the .out fileon a development board, you can create LabVIEW VIs to test the targetcode. You can transfer simulation data to the DSP target code from a VI andanalyze output data from the target code on the development board.Use the RTDX communication VIs to send data to DSP target code RTDXinput channels and to receive data from RTDX output channels. RTDXallows system developers to transfer data between LabVIEW and the targetprocessor without interfering with target code execution. The data inputscan be any test values you want to pass to the target code with eachiteration, and the data outputs can be any values you want to retrieve foranalysis from the target code after each iteration.© National Instruments Corporation3LabVIEW DSP Test Integration Toolkit for TI DSPThe block diagram in Figure2 shows how to send data to and receive datafrom RTDX channels of DSP target code running on a development board.While running, the DSP target code for the example expects sine wave data.The Simulate Signal VI creates a test sine wave. The CCS RTDX Write VIwrites the test sine wave to the WaveIn RTDX channel of the DSP targetcode. The DSP target code uses the test sine wave data it receives from theWaveIn RTDX channel.The CCS RTDX Read VI reads waveform data from the WaveOut RTDXchannel of the DSP target code. This example VI displays the waveformdata on a waveform graph.Figure 2. RTDX Communication with DSP Target Code Writing and Reading Data from DSP MemoryYou can access data from the memory of target processors.

In Figure 4, the CCS Symbol to Memory Address VI passes the current memory address of the run_flag symbol to the CCS Memory Write VI. The CCS Memory Write VI changes the value of run_flag to 0,stopping the target code loop.Figure 4. Writing Data Values to MemoryWorking with Target Code Data in LabVIEWYou can analyze, manipulate, and present test data the DSP target code returns. For example, on the block diagram in Figure 2, the DSP target code returns waveform test data to analyze in LabVIEW. A waveform graph displays the waveform data. Refer to the LabVIEW User Manual for information about the measurement, analysis, and presentation features of LabVIEW.Using DSP Test Integration Advanced VIsDenoted by a blue background, the DSP Test Advanced VIs handlelow-level CCS IDE and RTDX functionality, such as launching CCS IDE and enabling or disabling RTDX communication. Use the DSP Test Integration Advanced VIs when you want more control over CCS IDE andRTDX functionality.Use the LabVIEW ActiveX Property and Invoke nodes to control theCCS IDE functionality using the DSP Test Integration Advanced VIs.Refer to the the LabVIEW User Manual for information about using Invokeand Property nodes.LabVIEW DSP Test Integration Toolkit for TI 。
