Fixed point division on FPGA doesn't show the fraction part

Hi,
I'm trying to normalize a fixed-point complex vector. My problem is in the part of fixed point division. Assuming I am dividing x by y (x/y), then I multiply first x by 2^26 and y by 2^9 then divide both of them using high throughput function then multiply the result by 2^-17 and here the problem appears. The result is zero, and the fraction part doesn't appear. My question is: does the "scale by power of 2" block discards the fraction part and only keeps the integer part, even if the input is a fixed point input with fraction part of 20 bits length? If so then how can I get the result of dividing a number by a bigger one? I mnean how can I display a result < 1? If not, then why isn't the fraction part displayed? The numbers I used as an example are: x=10, y=182.
The indicator is adjusted to have 64 bit word length and 44 integer length. I also write this data into a memory element and then read it through a FIFO to transfer it to the RT vi. Both of the memory and the FIFO are configured with the same word and integer lengths above. I am using 7965R series FPGA.
Thanks in advance.

It's worth noting that I tried this same procedure on RT vi itself and the fraction part was displayed.

  • Dreamweaver design view doesn't show the bottom part of a long div

    Hi!
    I'm doing a very graphics oriented site, which basically requires me to use a large jpg as a background image and placing text areas against this background     using absolute positioning.
    My problem is that Dreamweaver doesn't show me the bottom part of my content div's background, but renders it as black instead. This obviously makes placing the text areas correctly difficult, since I can't see them against the background.
    If I turn on Live view, then Dreamweaver shows the bottom part correctly. But in live view I can't use rulers and guides (or can I?).
    Is there any setting that I can change so that Dreamweaver is showing me the whole div bg in all situations? One possible cause of this problem might be also that I'm using overflow:scroll on my content. Could that be why Dreamweaver hides the bottom part and can I change that behaviour?
    Any ideas are welcome!

    If we can see the page in question we could probably do this a lot easier.  But all you need to do in your CSS for the background is:
    background: url(pathto/image.jpg) fixed no-repeat;
    If you are trying to absolutely position something in the middle you will be unable to do this without the assistance of javascript to determine the useable pixels on the end-users computer.  Horiztonally is not the issue, but rather vertically because you can achieve horizontal centering by defining a width and setting the margin: 0 auto; in your CSS.
    As far as working with overflows, if there is too much content in them that you believe the overflow will be necessary (assuming min/max-widths are set) you could consider including the content from another document or store it in a database and query the information out.  Then it would make it easier for the client to update the content on their own in the future.

    My weather app doesn't show the feels like temp or wind, etc.  How can I fix this?  I am running iOS 8.1.2.

    is that really what it is?  this is the native iphone weather app.  the funny part is that when i use the actual weather channel app, it does provide it.
    is this an api issue with the weather channel and the iphone then?  i guess there's no fix?
    thanks for your help by the way.

    I am modifying the correct httpd.conf file on the server, it just doesn't seem to work. - If I put the rewrite rules in the <Directory /> the rewrite works but it adds /Library/WebServer/Documents to the URL.
    I also tried putting the rewrite rules in <IfModule mod_rewrite.c> but that did not work either.
    mod_rewrite is enabled and running on the server.
    I will post the rewrite rules again in the code brackets. Sorry for the long post. - If some one can try them out on their Leopard Server to see if they can get them to work, it would be much appreciated. Again, these work on my Leopard Client but I can't get them to work on Server.
    -- The httpd.conf file posted above is just the default conf file found in /private/etc/apache2/

  • Pages for iOS doesn't show the preview view of documents, a fix?

    I don't know if anyone has the same problem, but since the update, my pages for iOS (even in iPhone or iPad), doesn't show the preview view of each document. I have to open a document, close it and then it appears the preview. But if I close the app, all the previews disappear again and it shows the icon of pages (the orange pencil), which is awful by the way.
    So, anyone else has this problem? How can I fix it? It is not a big deal, I know, but I just don't like the way it looks like.
    I re-install the app and it doesn't work.
    Thanks!

    Same problem here. Some previews but majority are the icon diagram of the orange pen. It's the same on both my iPhone 5 and iPad 3. Hope they sort this ASAP

  • How do i fix my printer when it won't show the print preview for web pages? it worked and now not.

    how do i fix my printer when it won't show the print preview for web pages?  it worked for a while and now it doesn't.  printer is an hp officejet 7310 all-in-one.

    I would suspect this is a hardware issue.  The rollers are probably having issues picking up the relatively smooth thick media.  You might have better results be cleaning the paper pickup rollers with a damp paper towel.  Also make sure the paper is snugly loaded and the paper guides have been correctly positioned.

  • TS3274 My App Store shows 3 updates but when I go to it the screen is blank. It will not give me the option to update all or one at a time, it doesn't show the apps at all.

    My App Store shows 3 updates but when I go to it the screen is blank. It will not give me the option to update all or one at a time, it doesn't show the apps at all.

    Many people are having this problem for the last couple of days. This is a problem that Apple has to fix. If you look around the forum, you will see many, many discusssions about this and they have been going on for a few days.
    According to Fly150 in another discussion, this is a workaround - for the time being.
    If you want to update the Apps while waiting for Apple to fix Updates:
    1. Go to App Store
    2. Select Purchased
    3. Select All
    4. Scroll down to find the Apps showing update
    5. Select update on the Apps
    This should update the Apps and get rid of the update count in App Store.

  • HT2693 How come my apple map doesn't show the map on apple standard map.. However, it does work on google map. I was trying to close the apple maps, restart, and many other ways but still didn't work. Please help me.

    A standard map on my iPhone 4s is suddenly not working. It shows the blue dot but it doesn't show the actual Map where I can see the streets.
    I don't know how to fix this problem. I did try so many ways even restarted iPhone but still not working... Please help me out.

    Hi JinHDK,
    Yes I worked previously but it's now not working. I did double click home botton and terminate the maps many time but still not working.
    The standard maps just not show any route only the blue dot (my location.)  I really don't know what to do. Btw, I used to live in SF but now I'm traveling to Thailand. One of my friend is using iPhone 4S as well but his maps is working. So I guess it is about its application on my phone...
    Thank you.

  • The transfer function of the PID block doesn't show the derivator.

    Hello,
    I am trying to use the PID vi, but I when I try the box by itself, it doesn't behave as a "clasic" PID should behave. The main problem is that I don't manage to see the derivator. In the attached vi I compare the transfer function of the PID vi with the transfer function of a PID built by me. My version shows all what a PID should have: integral section (with decreasing magnitude and -90 phase), center area (with constant magnitude and 0 phase), and derivative area (with increasing magnitude and +90 phase).
    The PID vi only shows the integral part.
    You can also select a step input, and see the output directly. If you choose a large enough derivative time (100 times bigger than the integrator time), and you look closely to the first part of the output, you will see the pick due to the derivator in my version, but not in the PID.vi version.
    Does anyone knows what am I doing wrong? 
    Kind regards,
    Pablo Estevez

    Dear Nathand,
    Thanks for your answer, I tried the change and you are right. That shows that this not a standard PID, since that means (and actually I can see it now by checking inside the vi) that it is not using the derivative of the error but the derivative of the process variable. I know that this is used sometimes to prevent the effect of fast changing set-points, but it is a shame that they do not comment on it in the help, and that this is not a selectable feature. Do you know if there is a way to edit these pre-packaged vi's? 
    One more question, about the labview style. I included the sequences just to group terms and make the code more readable to separate the integrator from the derivator and not have a knot of entangled signals. Specially when I run the clean-up diagram, it gets very entangled. I have been looking for another way to do that (container boxes, groups). It would be nice if you could suggest me something I can do for it.
    Thanks again,
    Pablo 

  • WiFi ON/OFF button Doen't Work, the IPod doesn't show the on/off button in the Settings- General - WiFi

    After My IPod Touch 4th Geneartion was broken I had to fix the screen, which cost me a lot, after a perfect restore through the ITunes I went to connect to my IPod to the WiFi network then the WiFi ON/OFF button Doen't Work, the IPod doesn't show the on/off button in the Settings-> General -> WiFi.
    And another problem I encountered during this operation was that the Games I downloaded through the ITunes doesn't work, when I click on the icon ( Game Icon) it starts an then closes in a few seconds

    See:

    Settings > AirPlane Mode OFF, Do Not Disturb OFF
    If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

  • Thunar doesn't show the partitions mounted in fstab[SOLVED]

    Hi everyone,
    I am running XFCE 4.10 in archlinux and today when i added couple of partitions to fstab and rebooted my system I noticed that thunar doesn't show the partitions that I added to my fstab. what should i do to make it appear in thunar ?
    here is my fstab:
    /dev/sda5 /media/disk ntfs-3g defaults 0 0
    /dev/sda2 /media/disk-1 ntfs-3g defaults 0 0
    Last edited by pyarch (2012-10-03 22:03:54)

    Maybe an old thread, but I came up with a different solution. By default Thunar mounts NTFS partitions under
    /run/media/<username>/<UUID of NTFS drive> .
    If the fstab is updated with a path different from above for your NTFS partitions, they end up not being displayed in bookmarks.
    So, to overcome this, create your mount points in
    /run/media/<username>/<mount point dir>
    and point to those dirs while adding entries to fstab.
