Is it possible to filter design on FPGA reconfigurable on the fly?

Hello world

I wonder if it is possible to design multi-channel filters on the FPGA reconfigurable on the fly? For example, it is possible to have X bandpass filters in an iteration, and Bandpass Filters Y with different specifications in the iteration following without having to recompile the FPGA code? Is there a simple way to achieve such a purpose?

I have built such flexibility in the OTR (where each iteration has different filter settings) but hope to implement on the FPGA so.

If someone could provide ideas as to whether or not such a conception is possible, it would be greatly appreciated.

Thank you in advance for your help!

Steven

Hi Steven,

How do you try to generate the FPGA code for this filter, you are using the IP generator?

If so, this knowledge base article describes fixing the coefficients for multichannel to change on the fly filters.  There is also a nice example in there also.

Also, if you use this IP generator, this help document describes the more Options box that has the ability to change the coefficients to be 'rechargeable' so that you can change these on the fly it too.

  • LabVIEW FPGA: Not possible to create an executable file that uses the FPGA in Simulation Mode? I get a weird error code

    When I try to create an executable from a host VI that has an "Open FPGA VI" reference who has run, the value "Dev computer w / Sim i/o" value, the application is built without error but when I try to run it, it opens with an arrow broken to run and has the following error:

    "VI has an error of type 2302200.  The full development of LabVIEW version is necessary to correct mistakes. "In fact, he repeats this message two times in the same window for some reason any.

    Moreover, I * have the LabVIEW full development version and I use 2010 SP1

    While the error message is not as clear as it could be, you're right: you cannot run an executable file that tries to run an FPGA VI in the simulation.  It would be nice if there was an error in compiling.  I always forget to switch to run on the target FPGA before building my application and discover the error until I have it copied on the system in the laboratory.

  • Is it possible to have more than one location in the Google Maps widget?

    Hey people,


    Lets say, you design a website for a client with multiple banks, you just want to tell them everything, no?

    I just want to know if it is possible to have more than one location in the Google Maps widget. I guess it shouldn't be that hard, but I can't understand it...


    any help would be much appreciated!

    It seems that you can only use one address for this widget.

    To do this you will need create map in Google Maps with all your points, and then copy the Google embed .html into Muse.

  • Is it possible to have versions PDF and PNG in the folio "even".

    Is it possible when copying on articles to have a folio in PDF and the other in PNG?

    Tried to do this by establishing a different folio in PNG and the copy through the articles that were created for the original PDF folio, but they always seem to be PDF when loaded in the new folio and preview on Tablet, even if it has been set in PNG.

    They only get converted to PNG when published? shouldn't we see thumbnails in the DPS Folio Producer: Editor window. Try to keep the meta tags of data between folios, or do I have to re - export these files and to reintroduce the tags and attributes manually.

    I saw there is a way to copy items between folios admin level, this would lead to a correct transposition of the PDF to PNG?

    We don't have a way to create a sidecar of existing folios, unfortunately. As Bob says it is an often requested feature, it just not has not spread to the top of the priority list yet.

    Generally what I see happening is one person other that the designer is responsible for managing the file sidecar.xml. One person deals with metadata and designers, simply use FBP folios small test to check their work. When all files are made and verified using the appropriate folio import folder structure the person who manages the sidecar will create the final folio in FBP, which should be published, using the sidecar file.

  • How can I create a filter to remove only "junk" from the server?

    One of my email accounts is an important customer. I manage their online customer service. Normally our protocol must always leave all messages on the server, so that one Thunderbird account, I never put delete messages on the server.

    But the account has recently started a lot of unwanted messages. Thunderbird is doing a remarkable job to those tagging and placing them in the folder junk e-mail for this account. I would like to create a filter that could remove them from the server, preferably more than "x" days old so I could monitor activity to ensure that no important messages are removed.

    I noticed that in "Filters" I can create a custom header of my choice filter, but am unable to create what I want which is:
    -After the mail is marked as junk by Thunderbird to delete messages from the server, if they are older than "X" days (my choice of 'X').
    -not to delete all messages in the server for this account

    Try:

    • Right-click the junk e-mail folder and select "Properties".
    • Click on ' retention policy tab
    • He chooses to "use my account settings."
    • Uncheck this option for other options.
    • Select: for example: delete messages more than x days.
    • Click OK to save the changes.
    • Close and then restart Thunderbird

    It should be possible, but you must first case if your machine has the connector or not. You can check this by opening the second hdd cover and check if the connection is present.

  • How to clear the output buffer, possibly resize and burn again, before you begin the task of output

    I use PyDAQmx with a USB-6363, but I think the question is generic to DAQmx.

    I have an output buffer that I want to be able to (re) write to without starting the task output.

    More specifically, I have a graphical interface and a few sliders, the user can move.  Whenever the slider changes, a new set of values is loaded into the buffer output through DAQmxWriteAnalogF64.  After you set the value, the user can click on a button and start the task output.

    In some cases the change in cursor does not require a change in buffer size, only a change in the data.  In this case, I get the compalint following DAQmx as they tried writing:

    The generation is not yet started, and not enough space is available in the buffer.

    Set a larger buffer, or start the generation before writing data more than content in the buffer.
    Property: DAQmx_Write_RelativeTo
    Value: DAQmx_Val_CurrWritePos
    Property: DAQmx_Write_Offset
    Corresponding value: 0
    Property: DAQmx_Buf_Output_BufSize
    Corresponding value: 92

    In other cases the change in cursor requires both change in the size of the buffer and data modification.  In this case, I get the following, but only after that do a few times each time increase the size of the writing.

    DAQmx writing failed because a previous writing DAQmx configured automatically the size of output buffer. The size of the buffer is equal the number of samples written by channel, so no additional data can be written before the original task.

    Start the generation of before the second writing DAQmx or set true in all instances of writing DAQmx Auto Start. To gradually write to the buffer before starting the task, call DAQmx Configure an output buffer before the first writing DAQmx.
    Task name: _unnamedTask<0>

    State code:-200547
    function DAQmxWriteAnalogF64

    I tried to configure the output via DAQmxCfgOutputBuffer buffer (in some cases, by setting it to zero or a samples, then save again, in an attempt to clear it) but that doesn't seem to do the trick.

    Of course, I can work around the problem by loading data only when the user clicks the end button, but not what I'm asking here.

    Is it possible to "remake" the writing of output before you begin the task?

    Thank you

    Michael

    Today I have no material practical to validate, but try unreserving task before writing the new buffer:

    DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Unreserve);

    With a simulated device, he made the error go away in case the buffer is the same size.  You will need to validate if the data are in fact correct, but I think it should be (unreserving I would say reset the write pointer so the old buffer are replaced with the new data).

    I always get errors when you try to change the size of buffer if (on my 6351 simulated).  I posted some similar mistakes about the reconfiguration of the tasks here, I guess it is possible that this issue has also been set at 9.8 (I always use 9.7.5 on this computer).  If the behavior is still present in the new driver, and also appears on real hardware (not just simulated), then it seems that this is a bug of DAQmx someone at OR should be considered.

    I wrote a simple LabVIEW VI that captures the error in order to help people to NOT reproduce it:

    The best solution at the moment would be likely to re-create the task if you need to change the size of the buffer (or avoid writing data until you are sure what will be the size of buffer).

    Best regards
