Select Tools»RTDX»LabVIEW Debugging Workbenchfor RTDX Communication from CCS or select Programs»NationalInstruments»LabVIEW Debugging Workbench for RTDXCommunication from the Windows Start menu to launch the LabVIEWDebugging Workbench.LabVIEW DSP Test Integration Toolkit for TI Automating CCS IDE FunctionsUse the LabVIEW DSP Test Integration Toolkit VIs to control theCCS IDE and project files. 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. The memoryVIs communicate with the development board slower than the RTDXcommunication VIs, but you can use them to perform simple codemonitoring and control.The following target code runs on the target processor and executes a loopthat increases the value of the counter symbol until the run_flag symbolequals 0.volatile Int16 run_flag = 1;Int16 counter = 0;void main(){while( run_flag ) {// loop executes until run_flag equals zero.// counter increases during each iteration.counter++;}}LabVIEW DSP Test Integration Toolkit for TI © National Instruments Corporation 5LabVIEW DSP Test Integration Toolkit for TI DSPIn Figure 3, the CCS Symbol to Memory Address VI returns the memory address of the counter symbol and passes the memory address to the CCS Memory Read VI. The CCS Memory Read VI reads the value of memory at the memory address and this example VI displays the value of the counter symbol on the front panel.Figure 3. Reading Data Values from MemoryYou can control the target code by changing the value of target codesymbols. 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 。

LabVIEW多核分析和稀疏矩阵工具包介绍发布日期: 七月18, 2013 | 0 评级| 0.00 out of 5 |Read in English| PDF概览NI LabVIEW多核分析和稀疏矩阵工具包提供了高性能的LabVIEW多线程分析库，是在线或离线的大数据集处理应用的理想工具。

实际上，许多现实世界的问题可以表示为大型线性代数计算，而该工具包可以为这些运算减少所需的资源和总体的计算时间。

此外，该工具包包括稀疏线性代数函数，并支持单精度和双精度数据类型。

本文介绍了LabVIEW多核分析和稀疏矩阵工具包的用途和推荐用法。

目录1. 高性能多线程分析如前所述，NI LabVIEW多核分析和稀疏矩阵工具包提供了一系列高性能、多线程分析库，可以用来处理大型数据集。

这些库是专为基于英特尔®数学内核函数库(Intel® MKL)的Windows 操作系统而设计的。

该内核库是一个高度优化、多线程化的数学计算函数库，满足最高性能需求的应用。

此外，当您将这个工具包与LabVIEW实时模块一同使用时，这些库可以被扩展到LabVIEW实时（ETS）的目标中。

因此，用户能够使用多线程线性代数、基本线性代数子程序（BLAS）和基于快速傅立叶变换（FFT）的函数。

图1.多核分析和稀疏矩阵函数选板包含高性能、多线程分析以及稀疏矩阵代数函数。

该工具包提供了各种函数库，每个函数可以更好地利用多核CPU。

而且它还包含一组线程管理函数，因此用户可以调整应用程序的线程行为特性。

图2.线程管理函数选板包含有效管理线程的函数。

至页首2. 管理线程本节以两个矩阵相乘为例来介绍管理线程的方法。

管理线程时，首要考虑的是执行函数的系统中可用的内核数。

要获得目标系统的CPU特性，可以使用 CPU Information 函数。

此外，线程管理函数选板中的 Get Threads 函数可以在之后立即添加以获取可用线程的最大数量。

LabVIEW入门指南从零开始学习电气工程师的必备工具LabVIEW入门指南LabVIEW（Laboratory Virtual Instrument Engineering Workbench）是一款由美国国家仪器公司（National Instruments）开发的图形化编程环境和开发平台。

它被广泛应用于电气工程领域，为电气工程师提供了一个强大而易于使用的工具。

本文将以LabVIEW入门为主题，从零开始指导电气工程师学习LabVIEW，帮助他们更好地掌握这一必备工具。

一、LabVIEW的基本概念和特点1.1 什么是LabVIEWLabVIEW是一款基于图形化编程的软件工具，用户可以通过拖拽和连接图形元件来进行程序设计。

与传统的文本式编程语言相比，LabVIEW的图形化编程方式更加直观和易于理解，使得用户能够更快速地开发和调试程序。

1.2 LabVIEW的特点LabVIEW具有以下几个特点：（1）图形化编程：通过将各种功能模块以图形元件的方式组合起来，用户可以直观地表示程序的逻辑和功能。

（2）虚拟仪器：LabVIEW提供了大量的仪器模块和工具箱，可以方便地模拟各种实际仪器，如示波器、函数发生器等。

（3）数据流编程：LabVIEW采用数据流的方式进行编程，即当数据准备好时，相应的程序模块才会执行，这种方式减少了程序的冗余和资源的浪费。

二、LabVIEW的安装和基本操作2.1 安装LabVIEW首先，您需要从美国国家仪器公司的官方网站下载LabVIEW的安装包。

安装过程相对简单，按照提示一步步进行即可。

2.2 LabVIEW界面概述打开LabVIEW后，您将看到一个由工具栏、面板、功能栏等组成的界面。

工具栏提供了常用操作的快捷方式，面板用于显示程序的输入和输出，功能栏包含了各种功能模块和工具。

2.3 创建一个简单的LabVIEW程序接下来，我们将创建一个简单的LabVIEW程序，以帮助您初步了解LabVIEW的基本操作。
