12. 12 Main Benefits LabVIEW DSP Test Integration Toolkit Easily integrate measurement in your design process – Reduce development cycle time by identifying design flaws early in the development process –Develop robust DSP application software with more complete validation testing

13. 13 Typical DSP Development Process Proof of concept; Initial code development Code Development System Test & Analysis Code Optimization Optimize for memory and performance requirements System integration and testing; Deployment Flaws Undetected Flaws Undetected Back to Code Development to Fix Flaws Flaws Detected

14. 14 Moving Test Earlier in the Development Cycle Proof of concept; Initial code development Code Development System Test & Analysis Code Optimization Optimize for memory and performance requirements System integration and testing; Deployment TEST Fewer Flaws Undetected Fewer Flaws Undetected Fewer Design Cycles

15. 15 Testing Early and Often With LabVIEW Moving Test Earlier in the Development Cycle Fewer Design Cycles More Robust Products Shortened Time-to-Market

16. 16 LabVIEW Integration with TI CCS Core LabVIEW functionality –Intuitive graphical development –Seamless integration with I/O –Data publishing and presentation Library of functions to Automate Routine CCS Functions Communicate Directly to DSP through RTDX

17. 17 Diagram of Software Framework LabVIEW Development System TI Code Composer Studio LabVIEW DSP Test Integration Toolkit Development Software RTDX Measurement and Analysis Software TI DSP Design Software Direct Communication to DSP Development Board through RTDX Automation of Standard CCS Routines

18. 18 Example Use Case Test how a gain coefficient that is applied to an input signal will effect the output signal from the DSP 3 Parameters (RTDX Channels) –Input Signal (cinput) –Gain Coefficient (cgain) –Output Signal (coutput)

19. 19 Steps to Test Write DSP code in Code Composer Studio Know names and data types of RTDX Channels set in Code Composer Studio Implement CCS Automation VIs in LabVIEW Implement RTDX VIs in LabVIEW

20. 20 Steps to Test Develop DSP Code and Implement RTDX channels in Code Composer Studio

21. 21 Steps to Test – CCS Automation VIs Opens Project File Builds Project File Downloads.out File Runs.out File Click to Proceed

22. 22 Steps to Test – RTDX VIs Generates Sine Wave Writes Sine Wave to RTDX Channel “cinput” Writes Gain Coefficient To RTDX Channel “cgain” Reads Processed Signal From RTDX Channel “coutput” Click to Proceed

23. 23 Steps to Test – CCS Automation VIs Halts.out File Closes Project File

24. 24 DSP Test System Review Develop DSP code in Code Composer Studio Use Automation VIs to automate CCS tasks (i.e. Open, Close, Build, Run, etc.) Use RTDX VIs to communicate directly to DSP through RTDX channels
