Sends the data sequentially to the FPGA to a file during playback

Hi all

I am a new user of the Labview FPGA module, and I need your help.

I have a huge file in my computer and I want to treat my FPGA Module. I have a VI divided into small files first, but to my FPGA I do not know how. My idea is to create two blocks of memory in the FPGA in order to have a structure of Ping-pong, module while the second memory is written the first memory was read and the data is processed.

The first problem is to forward these data to my blocks (as text and the FPGA does not accept it).

The second problem is that I don't know if as it is made of wiring will work. Can you help me it wiring? I don't know if data should I wire in the host of the read method will go directly to the data items in the FPGA VI.

Created memories are 64 MB each. I work with FlexRio.

Thanks in advance.

Greetings from King,
Miguel.

What you want to do, is create a DMA FIFO to send data down to the FPGA.  Make the data type of the DMA a U8.  Thus, on the side of the host, you just read your data from the file, use the array of strings of bytes and write to the DMA FIFO.  On the side of FPGA, you read DMA FIFO inside a loop TO make your table and then treat.  You may need to use a different DMA FIFO to send data to the host computer.

  • LifeCam HD-6000 wrong with the audio and video lag during playback, also a problem with the autofocus.

    I have a Lifecam HD-6000 laptop. Since the first day, I had trouble with the audio and video lag during playback. It cuts sometimes several seconds each time. Any program I opened to view it. Windows Media Center, Real Player, Media Player Classic, etc.

    There is also a problem with the autofocus. It will randomly in and out of focus, more spoil videos that I do. Any help with all these problems? I've updated all audio cards, drivers, etc. I am running Windows Vista.

    Thanks for the follow-up report.

    Just a lit bulb. Maybe the answer, maybe a spleen.

    Look carefully at the audio track of the timeline in the vicinity of title of the file.

    The title of your file audio timeline shows: level of Volume or something else. If something else, click the tiny triangle where

    the red arrow in the screen shot is sharp and select the Volume and then level so that you end up with

    Volume: level as shown in the screenshot.

    Hope it's the factor involved.

  • Is there a way to prevent the deletion of a file during CHECKIN services?

    My scenario: I am creating a service that takes the current latest revision and creates a new one, using the same metadata and content. I'm almost done. The lack total that when I called the service (CHECKIN_SEL) the file whose path I provided in the parameter primaryFile:path is deleted. Of course, I can create a copy in the ~ temp directory, but I would rather prevent deletion. I have also observed that the log contains a line:

    (internal) / 6...    Files to remove: /app/domains/content/ucm/cs/vault/document/2001.zip

    I tried to analyze the service and I found the intradoc.server.DocServiceHandler.addFiles () method. This method calls another method, deleteFilesInDeleteList, in which the files appear to be deleted. It is, however, also an event filter, preDeleteFilesInDeleteList, triggered. So I created a filter code to undo the deletion, if certain conditions are met. The code looks as follows:

    public int doFilter (workspace workspace, DataBinder dataBinder,
    ExecutionContext executionContext) throw DataException,
    ServiceException {}
    BinderSnifferFilter.traceVerbose ("PreDeleteFilesFilter");
    Vector v = SharedObjects.getOptList ("dontdelete");
    If (v == null) {}
    return 0;
    }
    String prevID = dataBinder.getLocal ("prevID");
    If (v.contains (prevID)) {}
    BinderSnifferFilter.traceVerbose (prevID + "is confined (-1)" ");
    ((Map) executionContext.getCachedObject ("lockedIDsList")) .put (prevID, "1");
    Returns - 1;
    }
    BinderSnifferFilter.traceVerbose (prevID + "is not confined (0)" ");
    return 0;
    }

    Tracing orders help to confirm that the filter returns-1, I also found this thread:Re: what event of java filter is to remove which mentions the updated object cache of lockedIDsList .

    However, none of this seems to prevent deletion.

    I also tried to find a class that adds the "" files to remove: ' message in the log, without success. "

    Finally, I tried to lock the file by changing the owner/group/permissions in the file system. Curiously, the service has failed (the system could not read during CHECKIN), but in the end, the file has been deleted in any case.

    have you tried to change binder.m_tempFiles? You should be able to change the vector before cleaning module is called.

    Note: I have not tried...

  • Is there a maximum size or the limit of text file during storage and data transfer?

    HI -.

    We used WriteExtFile and AppendExtFile to store data in a CSV text file in a data folder in the same location as the executable files of Authorware.

    WriteExtFile ("data\\"^"Variable_Names.txt", Survey_Variable_Names)

    AppendExtFile ("data\\Survey_DATA.txt", Survey_Data)

    As a general rule, we always put our executable files on the hard disk of the computer (c) due to some issues we had with an incompatible network drive in the past.  Have the files on the C: drive, eliminated any network problem.  Our data has accumulated would be always stored on the C: drive as well.

    Now, we need to store a backup copy of the data on a server, on the C: drive.

    My question is: is there is a maximum file size that can be "read in" and then "written" using Authorware?

    My thought was to use ReadExtFile to read the content of the 'Survey_DATA.txt' file and use WriteExtFile to write these same data on a drive on the network, by adding the date and time at the end of the name of the file as a backup file.

    I used this logic, which is working to write on the "P": network drive

    WriteExtFile ("P:\\Survey_Project\\BackupData\\DATA_BACKUP_"^Backup_Date^"_"^Backup_Time^".txt", Survey_Backup_Data)

    Of course, the size of the original text on the C: drive file will continue to grow because "AppendExtFile" is used to add the data of every investigation file in the data file (CSV, each record on its own line).  If the size of the file we will read again (ReadExtFile) will also continue to grow.

    Is there a limit to what we can read in and then write back?

    Thank you!

    Scott

    My apologies, it has been a few years...

    CopyFile is a function that you can load the WinAPI.u32

    Once loaded, use it like this

    Success: = CopyFile (FileLocation ^ "Sourcefile.txt",)

    Destination ^ "DestinationFilename.txt") "

    Remember that you must include WinAPI.u32 with your packed files.

  • After burning DVD torrent, download the last 30 minutes of the film is cut off during playback on a DVD DVIX player

    I've been downloading movies and burn them on DVD for awhile. Recently, after burning them and play them on a DVD DVIX player, they stop with 30 minutes left film and light up in the next movie on the disc. When played on my computer via Windows Media throughout the film is there but not sound.

    Anyone have any ideas?

    If the movie file is complete... I don't know why the Divx player
    would fail to play to the end. Have you tried burning one
    file on a DVD just to see if he could play all the way to the end?

    DivX player is also compatible Xvid? You can use the
    utility to determine if your videos are free Xvid:

    You don't have to install it... just unzip the file and
    GSpot.exe left click to launch.

    As for the sound issue on your computer... maybe you need

  • Why 4 "Set to the image size" k shrink during playback?

    When I add 4 k video to a calendar and a shrink (scale) to 50% to make it fit 1080, it fits perfectly when paused, but then half size rereads in the sequence of the 1080 program window.  I think it's the best way to put 4 k on a 1080 sequence, but I do not know why my reading shinks size the video further when I play.  Thank you for helping me to understand what is happening here or if there is a better way to bring 4 k in a sequence of 1080.Screen Shot 2014-11-03 at 9.57.14 AM.png

    When I edit 4K, I leave the sequence to the resolution of the file (4K I draw is the Red parameter of 3840 x 2160) and the scaling to 100%.  But reading and again to solve (under the icon key in the program monitor) I change it to 1/4. Gives me a perfect playback of 1080 p on my external monitor.

    Something to try anyway.

  • Help... None of the exporting format, predefined work during playback

    Please can someone enlighten me...

    Ive moved avid liquid to adobe cs5 as it were out of options with each program.

    The problem im having after editing a clip is export. Ive exported in mpeg, mpeg2, mpeg to dvd, avi to Microsoft, and various different presets each time.

    I tried only about 10 seconds, first clips that I've never exported before.

    BUT when I play on my two different DVD and a blu - ray player, repeat me not supported format. I've done about 20 different clips all presets with different formats and not one worked. Ive also tried to change the codecs that accompanies the a.p.p.cs5 and still no luck.

    With avid was a simple case of merge it or burn directly on a dvd or iso registration and worked in all 3 players.

    Is there something hurts when im export?, do I need to install additional codecs?...

    Original video was shot by sony pd150

    PD150 DV SD so is after the change, your normal workflow would be to export to MPEG2-DVD to the creation with reminder and burn to DVD. All other formats are irrelevant here, since you start with the DV hardware and deliver on DVD. Uprezzing to BRD is not desirable, because of the serious loss of quality.

    The alternative is to DL (dynamic links) to still make your creation, or for export as MS, DV AVI, import into the still and still have to do the transcoding.

  • Very high CPU usage in svchost during playback of an event in a major newspaper of the events using WMI

    Hello

    I have a very high utilization of the processor in the process 'svchost.exe LocalServiceNetworkRestricted' during playback of an event in an event log in Windows 2008 64 SP02 using local or remote WMI.  The same happens using Wbemtest or C++ WMI code.  The use of WbemTest, "Open forum" (identical to one the GetObject of WMI API) read just one of recent events in the event log:

    Win32_NTLogEvent.logfile = "application", recordNumber = 2615657 (in this case, it was the id since the last event in the very large to the Application event log)

    takes 3/4 seconds consuming thant plus 50% of the monitored computer CPU.  This only occurs when the event log is very large (in my case 1 million records), the event log contains about 10000 events just fine.

    The problem is that I read the complete paper in a remote program and this product CPU usage charge too much CPU to the monitored computer.  I do not read the newspaper of the events one by one, but I'm using WQL queries but I do some GetObjects and the peformance is really terrible.

    Any idea what to change or search?

    Hello

    Do not put a semicolon at the end of the dynamic SQL statements.

    Instead of:

    RESULT: =... | MAIN_EMP_CODE | ';';

    Try:

    RESULT: =... | MAIN_EMP_CODE;

    You need a semicolon (outside the single quotes) to put an end to the assignment statement, but you don't need a semicolon (inside the single quotes) to put an end to the dynamic UPDATE statement.

    Whenever you make dynamic SQL code, ask someone (often yourself) "Is this really necessary?"

    Dynamic SQL is usually an accessory to the wrong table design.  Do you really need to have several tables that each must be updated in the same way, at the same time?  Are you create new tables so frequently that cannot keep track of their static code?

  • Transmission of data to the host of RT to the FPGA via DMA FIFO

    Hello

    I try to write data from a host of RT on target FPGA using DMA FIFO and then process these data and read then return of the FPGA target to the host of the CR through an another DMA FIFO. I'm working on the NI SMU chassis 1062 q, with the built-in NI SMU-8130 RT controller and target FPGA NI SMU-7965R.

    The problem I face is that I want to send three different tables, two of the same size and the third with different size, and I need one more small to be sent first to the FPGA. I tried to use encode dish with two executives in the FPGA VI. In the first image, I read and write the first table in a while loop which is finite (that is, a finite number of iterations). The second frame contains the process of reading and writing the second two tables (of the same size) in a while loop that can be finite or infinite (depending on a control). The problem is that it does not work. 2 arrays are displayed on the front panel of the RT VI host and works well, however, the table that should have been read in the first sequence does not appear on the front panel of the RT VI host. It is not sensible because if it is not passed from the host to the fpga and vice versa then the second image should not have been executed. Note that I'm wiring (-1) for the time-out period to block the while loop iterations until the passage of each item is completed. So the first while loop has only 3 iterations. Could someone help me undersdtand why this happens and how to fix this?

    I enclose a picture of the host and the fpga vi.

    Thank you.

    If you vote for my idea here and it is implemented, you can even omit the loop FOR fully.

    (I also propose the RE / IM divided inside the loop FOR and perform operations on complex table before the loop the transpose and reshape .) In this way, you only need one instance of these operations. You might even save some unnecessary allocations table in this way)
