Table 2D-fixed points allocated to the amount of disk space!


I'm trying to create a 2D table file that will be saved on a real-time target. And should be read by my application in real time.

To create a file as small as possible I have it recorded in fixed point format. (integer 16 bits 6 bits)

The table size is 1024 X 1024 data points which is ~ 1 M data.

If I save the file to the DBL format I expect to get 8 MB (each data point is represented by b bytes) of the file - and that's what I

If I save a U16 format, I expect to get 2 MB file - and that's what I indeed.

I waited get a 2 MB file with fixed point format-, but as you can see in the screenshot - I did not!

No explanation why the checkpoint file is fixed so great?

Thank you

The FXP is 64-bit internally.

  • Error message Microsoft Word "Word could not create the work file. Check the amount of disk space on your startup disk. »

    I have a MacBook Pro, retina 13inch OS X el Capitan Version 10.11.1 with 16 GB of memory. It's brand new and I have recently installed Microsoft Word/Powerpoint etc. a disc that I bought a few years to my previous MacBook. It seems to work very well, but whenever I want to open a word document a message comes up saying "Word could not create the work file. Check the amount of disk space on your startup disk '. However, once I click 'OK' this message disappears and my word file opens without a problem. I have 16 GB of memory on this laptop and it's new I have not reached anywhere near the maximum amount of storage so I'm puzzled as to what this message means. How can I avoid that this message popping up everytime I open Microsoft Word? Any help would be appreciated!

    This has nothing to do with memory - it's the SSD. Word tries to create a temporary file to use as a backup if the program crashes while you are working. First, run the Microsoft Update program to see if there are updates you have missed. Second, Microsoft currently supports only versions 2011 and 2016, so if yours is older, you should consider the upgrade. Thirdly, I suspect that the temporary file is not get created so that you have fewer cancellations (maybe any) and that if the program crashes you have to restore.

  • Best way to determine the amount of disk space is required for a deployment of office?

    It is counting on the OS and the numbers of virtual machines, for linked clone images, you might need a few of them, one for the standard user, one for the user of the task and one for users with power "admins".

    Also, is that the application will be with the operating system or using ThinApp?

  • How can I determine the amount of disk space is required to remove a snapshot of peacebuilding assistance, then a fret?

    I have a 27G vm running on Fusion 2.0.1 - the Mac OS X file system has only about 15 G of free space. I want to shrink the vm disk to release ~ 10 of unused space (which was initially to unpack a large SQL Server db that has since been removed in XP), however, I am unable to use tools to decrease because there are snapshots and cannot remove the last snapshot - when I try I get the error: «unable to clean deleted files» : There is not enough space on the file system for the selected operation. »

    I read other associated messages and understand how the snapshot deletion process works (stolen turns into the existing vm before be deleted). I tried a solution of possible workaround I've seen described elsewhere - creation of a new snapshot, and then remove the existing (old) snapshot and try to remove then the new snapshot - however, which results in the same error. If this procedure fails, a snapshot of the 'Consolidation of assistance' is sometimes created.

    I think that error indicates that space is insufficient on the Mac file system, is that correct? The 15G is not enough. If so, is there a simple rule that told me how much free space will be necessary?

    I think it's a darn good reason to buy a bigger hd faster for my Macbook - but thought I would ask first

    Thanks for your help - much appreciated.


    It depends on.  IF you have created your virtual disk as a monolith, then you need at least as much free space as the defined maximum size of the virtual drive.  If you created it as a disc of 2 GB-Split, then you need a little more than 2 GB of free space.

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.

  • to know the amount of free space in a tablespace


    I'm learning to oracle 9i release I had created a tablespace 'TOOLS' to use the default tablespace for Statspack.
    I would like to know the amount of free space available in this table space. To do this, I ran the following query, but there was no selected lines:-

    2 where nom_tablespace = 'TOOLS. '

    no selected line

    SQL > select name from v$ tablespace;


    Can someone say the reason for this.

  • Amount of disk space available on the disk hard keeps fluctuating.

    I have a Compaq CQ2103WM-B desktop running Windows XP, hard disk Go 139.  I started to receive notices of high memory use, began to receive notices of disk space is low. I ran the cleaning disc several times, it has been very slow, constantly showing only 2 bars, sometimes for hours. He finally released the space and I have deleted several programs and files, emptied the trash. After a few minutes the amount of free space started going down again. For several days, I kept repeating this process, but keep decreases the amount of free space on the disk. Now, it fluctuates to the amount of free space on the disk every few minutes. I downloaded and ran CCleaner, it frees up space and again it has disappeared in a few minutes. He got so low that I can't watch videos, use system restore, download other software or software upgrades (like Norton), cannot download pictures from my camera or save files in programs such as Corel Draw. Right now is 3.97 MB free space, he went down in the KBs, sometimes it goes up, but it changes even if I do nothing. I scanned for viruses and malware, Norton managed to reach space, but it lasted only a few minutes. I don't know anything else to try. Would it be a software problem, the malware that Norton cannot detect, the hardware, or if my system has been hacked and someone uses free space on my computer? Any information would be appreciated.

  • Estimate the amount of temp space an application take?

    I have a query that is "SELECT * FROM Field_Name ORDER BY une_table DESC. une_table has an avg_row_len of 458 bytes and stats are updated. There are about 6 million lines in une_table.

    TEMP is set at 500 MB and the request fails for lack of TEMP space. I show about 176MB TEMP is currently ongoing usage, so worst case scenario I 324 MB of free space.

    So what calculation is correct for the amount of TEMP space is necessary:

    (a) avg_row_len 458 * 6 000 000 = about 3 GB of space (and DBA_SEGMENTS agrees with this rough math). That's assuming that this puts the whole line in the genre.

    (b) 6 000 000 lines * 4 bytes for a ROWID (I think they are 4 bytes) = 22 MB. That's assuming that it sorts just a bunch of pointers to rows (which is how I thought it would work).

    Don't forget to add the length of the column in which the length of rowid will be sorted before you multiply. A rowid [url] has four pieces, a four bytes. Also, check your plan, in case there is more that just the kind going for you.

    Appropriate Sort_area_size or target of the pga, you can reduce the need for temp. Pga memory management in the docs, see [url] to start.
