Help DSP Module

Hello. I am working with Labview DSP Module to program DSK 6713 board. I take samples of microphone imput and I need to know what is the framesize maximum that I can use. Are there some way to increment this framesize? For example, importing custom C code into Labview DSP Module.
Regards.

Hi All,
I have done some further work on this, and have discovered that with the example code given in the help file on the Block Wizard provided at ( ftp://ftp.ni.com/support/labview/labview_dsp/ImportingCCode.zip) , I can make a new AI block, and the sub-VI runs correctly and I can see whatever is applied to the DSK analogue input on the screen in a LabVIEW graph, but when I connect the new AI generated from the code given in the help to the default AO it doesn't run (see attached zip file containing sub-VI, test VI which calls it). 
Can anybody help me with this?
Is the Importing C Code to DSP module supported?
Thanks,

  • Using DSP Module to control C6713 DSK

    Hi,
    I am doing an Automatic Noise Cancellation design, and am using the LabView DSP Module and downloading code to a TI C6713 DSK.  I need 1 microphone to measure ambient noise, and a 2nd microphone to measure my desired speech signal.
    I would like to use the MIC_IN input for one microphone, and the LINE_IN input for the 2nd microphone.  The DSK has a stereo codec, so I would like to have one channel be the audio from 1 mic and the 2nd channel be the audio from the 2nd mic.
    First, is it even possible to do this?  If so, how do you use LabView to configure the DSK so that each channel represents the audio from 1 mic?
    Thanks for any help.

    You definitely can target the TI TMS320C6713 DSK with LabVIEW.  You can create a DSP project in LabVIEW 8.2.1 that will add all available I/O to the project.  You can then use this I/O to bring in your signals to do any LabVIEW analysis available for that target.  As for how you the I/O actually works, TI may be the best people to contact for that.  Here is a few links where I found some of this information.

  • Labview dsp module with tidsk 6713

    Hi,
    I'm working with TI DSK6713 board on Labview 8.6.1 version with the Labview dsp module 8.6.
    The idea is to delegate computationally heavy FFT operation to DSP processor computing it many times in a loop.
    As FFT is tailored for DSP and, in fact, Labview DSP tool has build-in FFT module, it should operate much
    faster on DSP rather PC. So I expect to have acceleration here, and I don’t see that so far.
    Does anyone observe performance accelaration with labview dsp compared to labview only performance ? What are the tools for measuring timing statistics on labview dsp ? 
    Thanks.

    Hey Salander,
    I am an applications engineer here at National Instruments and would like to get a little more information from you to see if I can help you with your issue. I am not particularly familiar with the TI DSK6713 as it is a third party product. It seems to me like you think that since the TI DSK6713 has a DSP processor it should hypothetically run LabVIEW DSP faster than your PC. I am wondering if the TI DSK6713 is fundamentally different than any other board. 
    Here is a link to the manual for LabVIEW DSP that might have some helpful information for you that could shed some light on your issue:

  • An arbitrary waveform generator using the DSP Module

    Hi Guys,
    Just got my hands on LabView and the DSP Module, and having a bit of fun atm. Great products. I'm currently using the TI DSK6416, and was wondering if there was a labview model/example of arbitrary waveform generation using this...? Perhaps using a DDS method or something similar?
    Thanks in advance...
    GibbGodD 

    GibbGodD,
    Hello!
    There are quite a few Waveform Generation VIs within Labview, including the Simulate Arbitrary Signal Express VI and the Arbitrary Wave VI. Unfourtuantly, these are not available within the DSP Module. There is a special group of Embedded Signal Generation VIs for the DSP Module, of which one is the Simulate Signal. Take a look at these VIs as perhaps you could use them to build the waveform you are looking for.
    To answer your question, I wasn't able to locate a specific example that matched what you were looking for, but if you to Help >> Find Examples >> Toolkits and Modules >> DSP from within LabVIEW you should be able to find some great DSP examples. Particular, the example project "Variety of Signal Types.lvproj" shows the different types of signals the DSP target can generate.
    The majority of Arbitrary Waveform Generation information that I was able to find is all related to our Function Generators but not for the devices supported for the DSP Module.
    Best of Luck!

  • Histogram in DSP module

    I am trying to do a histogram in LabView DSP module. First, is it possible? If so can it be done? Any advice would greatly be appreciated.

    Hi,
    There are great examples of File I/O in our Example Finder, accessed at Help»Find Examples. Expand the Fundamentals tab, then the File Input and Output tab, and choose an example that works for your application. "Write to Text File" is a great place to start. Implementing this into your existing code or vice versa should allow you to accomplish your goals. Happy coding!

  • F4 Help in Module pool and restricting the entries

    Hi all,
          I was looking how to give F4 help in module pool program and restrict the number of entries on tht event.
    Take a example of VBELN, it is having number of entries so for F4 help we first take all the entries for VBAK for VBELN and then use FM 'F4IF_INT_TABLE_VALUE_REQUEST' and pass the table.
    So how can we restrict number of entries initially 200 and then user can input number of hits.
    ( How to use Callback subroutin ).
       Waiting for valuable additions.
    Thanks,
    Anmol.

    Hi ,
        This is my query, I want to restrict the number of entries fetched by the search help depending on the user input like in standard help.
    Like VBELN is having number of records how can we asign a help to field like VBELN( for example ), is there any way to restrict the entries on search help rather than selection all the entries for tht field from database which is not good for performance. Like initially it should fetch 100 or 200 records, then if user want more entries to be fetch he can input the number of entries like in standard help. Any idea on this.
    Thanks,
    Anmol.

  • Speedy-33 Echo Example with DSP Module's Variable Delay Block

    Hi,
    I was trying to implement the echo effect using the DSP Module's Variable Delay Block, it works fine and I could hear the echo nicely, however, it was restrictred to the maximum delay of 4095 (for frame size of 1, and 4094 for FZ of 2, etc....). This means that the maximum delay I could get is 0.5 second with 8k sampling. May I know what is the reason behind? is it due to the HW buffer or what? and how to workaroud this?
    Thanks

    Remember that Arch Arm is a different distribution, but we try to bend the rules and provide limited support for them.  This may or may not be unique to Arch Arm, so you might try asking on their forums as well.

  • New to LV DSP Module,ask about the supported functions

    Hi all,
    I plan to use LV DSP module, but I am not sure if this module supports legacy LV functions. I looked at its manual, it only mentions DSP module supports many DSP specific functions.
    Does it support linear algebra functions like eigenvalue/vector calculation in the target DSP device?
    Thanks !
    Sunny 

    Hi Sunny,
    No, I don't think some origianl LV functions are still available with DSP targets. Because some mathematical functions are calculation-consuming, their algorithm need to be specially optimized when transformed to DSP targets. Please also notice that the LabVIEW DSP module only supports several targets including the
    NI SPEEDY-33, Texas Instruments TMS320C6713 DSK and TMS320C6711 DSK.

    Can somebody please suggest what components shuld be included in a help desk module.. and what will be required..So you know you want to build something, but don't know what it means. Then just write a "Hello World" Servlet and declare it to be your help desk module. Since no-one seems to know what the help desk module is supposed to do, you can rest assured that it will fulfill all known requirements.
    I have no idea as i have never done this beforeThen ask whoever told you to write it. At least they should know what it should be able to do.

  • Using Scope for LabVIEW DSP Module

    I have a DSK6416 board and it is supported in my LabVIEW DSP Module on my LabVIEW 8.6 Professional. I want to use two scopes, one for the input audio signal and one for the output audio signal of my board. Which one should I use? NI-SCOPE or Two Channel Oscilloscope? Does NI-SCOPE support any dsk? Does two Channel Oscilloscope work with my real-time project?

  • Trunk card and DSP module for AS5350XM

    I have bought Cisco AS5350XM Voice (PVDM2) High-Density (AS535XM-2T1-V-HC).
    There are 2T1 port and two 64-channel DSP modules
    My application server uses only G.711(64k) via LAN to talk to AS5350 for inbound IVR calls. If 2T1 is used to full capacity, there should be 82 DSP channels available.
    Could I just buy a trunk card (AS535-DFC-4CT1) and use only 3T1 without having to add extra DSP modules?
