Intertwining of the tables on FPGA

Hello

I am trying to interleave 1 3 tables for writing a FIFO DMA on an FPGA, but I can't make it work properly. When I try 2 1 tables it of ok, but with 3 elements are not properly interlaced and the result is that all 1 3 bays are mixed up.

I tried to use the interleave with 3 entrances and gives the mixed result, and I also tried to striping and striping 2 tables then the 3rd in this table. It works better that at least I get 2 tables properly interlaced, but the 3rd one is missing. For the test I used 3 sine waves each of a different magnitude, but the same frequency, using the input function 3 the result is a sine wave in a sine wave. 2, interlacing and then the 3rd in this table are reflected in three waveforms good but table 2 and 3 are identical.

According to the help, it is possible to use the interleave on an FPGA at the entrance and the results are tables 1 d, which combines 3 1 the tables should be, I think...?

I tested the service in a standard vi and it worked fine so the question is of course to the fact it's on an FPGA, but this is because of the FIFO, the function interleave or something else?

The material is a 7856R if that makes a difference.

See you soon,.

  • Impose a factor of scale between the model and FPGA

    Hi all

    I have a VS project configuration that unfolds on a real-time system. The project has an FPGA and a model. Some of the output of the cards of the OD of the FPGA model. In addition, some of the AI of the FPGA cards at the entrances to the model. Here's my problem. The AI FPGA gives me a measure of voltage, but the model takes only a pressure (bar) as input. This means that I need to convert my blood pressure using a table or a formula. How to make that happen?

    Also, I want to use the same lvbitx FPGA and the same model of dll on various physical parameters. The only difference between these physical configurations is the forumla/table (for example, a different pressure sensor is used). Is a convinient way to say VS use different table games?

    Hi oeua.uoeuau,

    If you have a formula to convert the voltage in pressure, you can use a calculated string to implement. You just point to the computed in your Channel FPGA output and the inport of your model to the computed string. If you need a table of choice, you can create a model of LabVIEW that takes blood and uses a lookup table to get the pressure reading and the outport of LabVIEW model port in the inport else your model.

    To switch between the different scallings, you can simply use a procedure to set a variable to be an entry or another.

    See you soon,.

  • To refer to a table control FPGA

    I develop a cRIO application that includes a table of 23 controls in the FPGA.  The generator of FPGA Interface C API them defined as a name and size.

    typedef enum
    {
    NiFpga_ControlArrayU32_Setpoints = 0 x 8118,
    } NiFpga_ControlArrayU32;

    typedef enum
    {
    NiFpga_ControlArrayU32Size_Setpoints = 24,
    } NiFpga_ControlArrayU32Size;

    How do I référenceriez the 15th point, as NiFpga_ControlArrayU32 [15] or as an offset to 0 x 8118?

    Hi Paul_Knight,

    When the C headers are generated, there should be one called NiFPGA.h.

    There is a function within this header to read a U32 matrix. The function is called NiFpga_ReadArrayU32. This is a documentation on the different functions of reading table.

    http://zone.NI.com/reference/en-XX/help/372928G-01/CAPI/functions_readarray/

    You should be able to read the values in the table and store them in an array in C. You can then access them as you would normally in your program C. I hope this helps!

  • How can I display the table of contents for the iPod Touch to 6

    When I opened first of all iPod Touch Users' Guide, I used the table of contents (TOC) to locate and access sections in the manual. But, after looking through the manual for awhile, I tried to return to the table of contents, but it wasn't there! I have tried various things to see if the table of contents are being hidden, or if in some way, it has been deleted. Anyone can shed light on this mysterious event?

    What is the version of iBooks that you speak? There is an online version here: https://help.apple.com/ipod-touch/9/ Aha, I see the table of contents on the left disappears if you zoom before or make the narrow window and reappears if zoom you out or make it larger.

  • How can I create a custom button to format the table borders?

    I often paste to Excel in a message e and would like a button or a context menu for the PROPERTIES of TABLE FORMAT it takes 2-3 clicks each time to access. Is there such a thing? I searched the Add-ons nothing helps. There may be a change in config I can do which would have the table to stick with borders already in place (I have to change the thickness of the border on '1' each and every time that she missed to '0' - maybe there is a place to have it by default on '1'?)

    I have attached a picture of the menu on that I wonder.

    I don't know of a setting for this...

    It would be easier to click on, but based on underscores bit indicating the keys Accelerator, the keyboard sequence would be:

    • ALT + o b o
    • ALT o b o

    I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

    Yes, you can have a one word title, by assigning a paragraph style title to this one word. No, you cannot change the text in a Table of contents, but you can change paragraph style font attributes (line) and add for example, a head of points between the types of OCD paragraph and page numbers. No part of the table of contents will not provide hyperlinks in exported PDF documents.

    When you look up in the menu bar, you can see the word iPages, or simply Pages. There is no product of iPages.

  • Changing the font styles in the table of contents usingpages 5.6.2

    Hello

    I am writing a scientific assignment and I have some titles that contain italic characters such as: Importance of Bacillus cereus

    When I create a table of contents, these italics seem to disappear and I can't do these italics without making the entire table italic material - that is not what I want.

    I also have the same problem with the degrees symbol which is great script in my titles, but appears as '0' in the table of contents.

    Can anyone help please?

    Thank you!

    When you build a Table of contents, Pages v5.6.2 uses a brush regular Helvetica on all text in the generated TOC. He made his farewell to all the attributes of fonts can set up for your titles and headings. We can not selectively reapply text attributes to a part of a table of contents entry.

    If I use the degree symbol in the title or the title paragraph style, she survives as baseline Exhibitor in the generated table of contents. My degree symbol is entered as shift + option + 8 (on a U.S. keyboard).

  • Size of the table only includes not Keynote - can not enter directly px

    I inserted a table on a slide, and he made two unexpected things:

    1. it will not allow me to directly enter a width of table in pixels - as soon as I enter a value, it returns to the original value. The only way I can change the size of the table is with the up/down arrows, essentially pushing a pixel at a time.

    2. when I add an additional column, rather than tighten it in the width of the table by adjusting the size of the existing columns, it blows the table out of the slide area, and I have to manually resize the table to accommodate.

    I have looked through all the parameters of the table and just cannot find why it behaves in this manner, which is different from the other tables I've created in the past.

    1. You are right. Selecting the Table tab and reduce line and column values will shrink your table, but the table resizing is not supposed to work this way.
    2. Control-click or two fingers press the alphabetical table header and select Add column after from this menu. The new column is added in place, and the other columns shrink and walk left to accommodate the new column, while the table itself does not move.
  • a cross on the table cell

    Is it possible a cross on the table cell?

    The term "strike" can have multiple interpretations.

    1. As a checkbox clickable?
    2. With diagonal lines, which intersect?
    3. With vertical lines or horizontal hash?
    4. With table cell fill of a model image pre-built?
    5. With gray scale or the fill color, without content, to suggest the use of cell?

    Pages, you didn't say what version, so I'll use v5.6.2, does not provide the points 1, 2 and 3 for the cells in a table.

  • Numbers: How lock the table without blocking the ability to edit what is inside?

    everything in the title

    Thank you

    Hi Berendirih,

    Is not possible. The lock table prevents changes to the table and its contents.

    Whenever possible, you should separate entry and calculations on their own tables. Lock tables calculation in order to protect the formulas. Leave unlocked data input tables to allow data entry.

    Define theLabels to {"Alvarez", "Flax", "Laundry", "Products"}

    I arbitrarily chose to line 3 of the table to demonstrate the problem.

    Each data item is associated, due to its position in the list, with a label that determines the column of the data table, where it should be placed.

    The illustrated script pitches the 2nd data element in the list in the column headed "Lin".  This seems to work ok.  But if q is set to 1 the script fails with

    get address of column "Alvarez" in line 3 of table 1 to sheet 1 of the document 1

    -> error number - 1728 column "Alvarez" in line 3 of table 1 of sheet 1 of document 1

    It fails also with q the value 3 or 4.

    I probably did something really stupid, but I can't understand this behavior.  Advice please?

    Under: Numbers v.3.6.1 Script Editor 2.7 2.4 OS X 10.5.5 Applescript

    Two questions.

    (1) the order of the text in theLabels = {"Alvarez", "Flax", "Laundry", "Products"} and differ from the order of the text in the header row. Is this correct?

    (2) you are putting the value 22 (point 2 of nominative) in cell D3, where column heading of D = "Flax", which is article 2 of the theLabels?

  • Impossible to change the name of the Table in figures

    I'm unable to change the title of a table, when I change the title name and press on enter it reverts to the original title. I tried to click away and save the document, but both go back to the original title. The only way to work is, it seems if the option a table a few times then start trying a new title.

    This can happen when you have a table with the same name on the same sheet.  Numbers of refuses to accept the name "double".  Check the names of the tables on the al sheet again.  One way to do that is to click the right part of the tab "" at the top with the sheet and inspect the table names in the drop-down menu that appears.
