Increase the speed reader

Hello

In fact, I use a cRIO for control of the kidnappers and a file.

The FPGA is use to combat (PID, conversion and emission).

My problem is the time to read the file value. My use of VI s 600ms to read the right line. If I reduce to 72ms, it's perfect. But if I reduce to 100ms which is very good also.

Before that the control, I do a PDM file with all the useful values for the control (as the command). Another file format is better?

What is the best corner to read this file fastly?

Unfortunately, I can't post all my code. In the parties not posted, I develop the cluster and save information on shared variables.

If the file is not too big, you should read the file into memory, first of all, then the data points instead of trying to access the file line-by-line access. If the file is too large, you can use a queue structure to read portions of the file in memory (producer structure & consumer). A single loop will control the amount of data is responsible for file in the queue and the other loop can remove data and sent to your remote device.

  • Increase the speed to setting 5672/PXI-5671?

    Hello

    I was wondering if it would be possible for materials OR to include an option on NOR-RFSG drivers later to increase the speed at which the lock 5672/5671 on a frequency? Will you please correct me if I'm wrong but I think that the reason why it takes a long time for the converter will sometimes be resolved is because he is trying to get a high level of accuracy when the configured frequency locking. Is it not possible to give a developer the ability to relax the constraints of precision so that the converter captures a faster frequency? I'm looking to reach speeds of adjustment faster than 10ms, regardless of the size of step frequency setting. I know that there are other variables that influence the speed of adjustment of the hardware, but I know that I realized a 45 ms speeds setting before as mentioned in this other post I did long ago http://forums.ni.com/ni/board/message?board.id=270&message.id=4749&query.id=320040#M4749.

    I'm sure that, in order to do this, if possible, there will be some changes of deep level in the RFSG code driver but I hope that it is possible.

    Thank you

    Tim Sileo

    You are absolutely right with your assumptions.  The speed of adjustment is limited due to other factors, including the accuracy of the configured frequency.  Therefore, a limitation of the actual hardware, even with driver updates, this feature would not be possible.  I want to point you at the suggestion of product section where you can enter any suggestions for new features, as it is something that our new RF hardware will be able to support.

  • Increase the speed of acquisition of a coding of LABVIEW

    Hi people,

    I use digital USB 6509 advice to do some multiplexing.

    Then, I use USB-6255 boards to get some blood pressure measurements.

    The acquisition is a bit slow and I am trying to increase the speed.

    Structures of the case?  I don't see any business structure.  Do you mean the sequence Structures?  You don't need those at all.  Just spread the wire of the error (ie the use stream) to force your execution sequencing instead.

  • Increase the speed of this VI?

    It is a simple question - is anyway to increase the speed of the VI below?  Parallelize the outer loop, I'm given the sequential nature of the loop inside, I don't know if there is anything else I can do.  The problem is that I'm trying to eat a large amount of data - every second I'm producing about 1.25 MECH. / s and any attempt of this accumulate more than 10 s (Data In) to perform the calculations below on several periods of integration (iTime; currently 0.001 0.01, 0.1, 1 and 3 s) - and it is causing an overflow on some other loops.  Any help is appreciated.

    Hmmm... isn't using table subset incur a calculation that does not remove the table?  I'll have at least one node of multiplication (I * chunk size) to add to the inner loop that was not there before to keep the appropriate place.  On the other hand, which gets rid of the shift register.  Is there a significant difference in performance between the subset of table and delete...?

    Looks like you're right about single-precision calculation - can be significantly faster.  I will consider this.

    Thanks, Darin.

    You must test in LV12, in previous versions, remove that table is a dog, even when the end of the table is deleted.  I did a simple test, create a table of random numbers 50000 and take the average of the consecutive blocks of 400 items by using the two methods.  I even added a reverse table of subset test to match the behavior of deleting the table.

    Results:

    Delete: 2.7 msec

    Subset: usec 200

    your mileage may vary.

  • I don't think that my fan does not work, not very hot at the air inlet, can I increase the speed of the fan?

    Is it possible to increase the speed of the fan, my laptop is not hot enough?

    In other words, it must be controlled by the motherboard. Points to check are all the ventilation grids which allow the air make sure they are free of lint, pet hair, dust, etc. If there are panels that can be removed (as for the HDD or RAM upgrades), delete and wipe any dust, etc, from there. With the panels off, get a can of air spray to Wallyworld, Staples, etc. and blow through the orifices of evacuation to the inside. That should dislodge from the heat sink.
    After a thorough cleaning, the outgoing air should be slightly cooler. Keep in mind that the more stressed the CPU and GPU are, more air is exhausted. If you think there might be a problem, there are a number of utilities that will control the fan speed and the different system temperatures:

    HWMonitor http://www.cpuid.com/hwmonitor.php
    CoreTemp http://www.alcpu.com/CoreTemp/
    Http://www.almico.com/sfdownload.php fan speed (also allows the fan control)

    If you used to use the laptop on your lap, you can think about getting one of the aprons to put on; very often, during its use on the knees, some of the Airways under may be blocked by your pants, causing overheating. I had a Logitech, which has a sliding mouse (I can't stand the touchpad), and it has helped tremendously with my gateway heat problem.

  • Increasing the speed of the mouse beyond Windows maximum.

    Is there a way to increase the speed at which my mouse moves across the screen above the maximum windows if I set the speed of the mouse up. I have improved pointer option selected & wish on with maximum speed. I use a mouse intellimouse Explorer 3. & don't want to really upgrade to an another gaming mouse. I thought would be simple because most of the games have an option where you can control the sensitivty.

    Hi, classify,

    Once the speed of the mouse is set up there is no way to increase the speed beyond.
    You may need to upgrade your mouse.

  • How to increase the speed of the PC without adding RAM

    PLEASE HOW CAN INCREASE THE SPEED TO RUN THE PC WITHOUT ADDING MORE RAM

    Some reasons for the slow pace of the computer:

    1. computer has not been maintained - http://www.elephantboycomputers.com/page2.html#Maintenance

    2. the computer is infected with the malware - http://www.elephantboycomputers.com/page2.html#Removing_Malware

    3. the disk is too full. Remove useless stuff, uninstall unused programs. Do not forget to save!
    http://www.elephantboycomputers.com/page2.html#Backing_Up

    4. flaky third party software. Toolbars and modules are particularly guilty in this area. Uninstall toolbars (Google, Yahoo, ISP brand, etc) and look at what modules are in use in your browser (s).

    5. computer has too many unnecessary programs/processes running in the background. Manage your Startup:

    For XP - How to troubleshoot using the Msconfig in Windows XP utility - http://support.microsoft.com/?id=310560
    The free Autoruns program is very useful for managing your Startup - http://www.microsoft.com/technet/sysinternals/default.mspx

    For Vista/Windows7 - Start Orb > Search box > type: msconfig and when it appears in the results area above, right-click and choose 'run as administrator '. Autoruns is also very useful.

    6. the user runs an inflated/invasive such as Norton and McAfee antivirus program. Replace it with a better program. I recommend NOD32 (commercial) or Avast (free). Avira is also good, but the free version has an unpleasant reminder screen (Google for instructions on how to disable it). The user can also run several real-time antivirus/firewall/security programs.

    7. the user has installed new programs that are processor and/or memory-intensive (Photoshop, AutoCAD, Mathmatica or similar) and does not have the power of the equipment.

    8 drive fails and is in PIO Mode. It's very much slow (like being in 1985). See Hans-Georg Michna here information - http://winhlp.com/?q=node/10

    In addition to the above, see also http://miekiemoes.blogspot.com/2008/02/help-my-computer-is-slow.html

    Note: If the computer has always been slow, in addition to the above user may have bought a machine with a less powerful processor and not enough RAM (memory). The normal use of the computer, 512 MB to 1 GB is sufficient for XP; Vista should have a minimum of 2 GB; Windows 7 is less demanding than Vista, but the minimum of 2 GB should also be used.

  • Torch: OpenVG will increase the speed in real time for the scaling\rotating image?

    Hello!

    I have such a problem. I need to view the satellite map (not vectored) with the possibility of scaling on in real time. Map is a bitmap either 1500 x 1500.

    I'm doing the scaling that requires 480 * 360 for operations return the second part of the map on a defined scale, but it is not enough - it is slow to make good zoom in real time.

    Maybe someone knows is it possible to increase the speed by using OpenVG? (OpenGL is not supported in the torch)

    Thank you for your attention.

    Realization of OpenVG for play ~ 1500px x 1500px images, rotation & them staggering realtime works pretty fast.

    So if someone needs of fast image processing to use OpenVG

  • How can I increase the speed of the fan on my computer?

    My computer keeps overheating and I'll try to find a way to solve this problem. And I think that by increasing the speed of the fan stops my computer from more than heating. In fact how can I change my computers fan speed. I have windows 7. My computer hangs when I play and sometimes it crashes randomly.

    Steven

    Increase the speed of the fan is not the solution.  You will wear just on the fan, and then the computer does not start.  If your computer is a laptop, it is not designed to play games.

    You should carefully, using compressed air, blow out the fan and heat tube.  You can also get a cooling block, don't play on a soft surface and if plant you yet stop playing games unless you want to kill your computer for good.

    SA123, just a reminder to the Oracle read model of consistency that default writers blocking not the readers and all the readings are a consistent point in time.  The net effect is that there are many posts in the past where developers who were to get the maximum value of the target table do not understand why their application is either get ORA-00001 errors (duplicate key) or when the value was not not a single key to end up with duplicate values.  When there is simultaneous DML sessions that time question at the same time, then the two session will get the same point in time and see the values of data at that time there at the time.  Meeting A updates the row but Session B sees the same prior value and then does its update by using the same value resulting in data incorrect or a value in double feature of indexing error.  You won't have this problem if you have only one update process, but it is a potential problem, if you have concurrent updaters.

    - -

    Therefore, single-threaded access in some way.  Select update would be one of the approaches and locks user (dbms_lock) would potentially another.

    - -

    Are you really working with a sequence in a groupID then if the chances of any two sessions simultaneously access the same group id is low so a select for update on the groupID you would manually calculate and provide the value of SrNoo with a low impact on scalability, providing the GroupID SrNO is indexed and there are only a few SrNO values by group.  However, why not just use a sequence and order lines in a SrNo by GroupId?  Which would eliminate the need to interpret the existing lines of SrNo on insert and save, you work on each insertion.  That what you are looking for better performance, this seems to provide the appropriate functionality.

  • What values can I change to increase the speed of mouse wheel?

    It seems that there are a couple of entries that you can change to increase the scrolling speed:

    -mousewheel.default.delta_multiplier_y

    -general.smoothScroll.mouseWheel.durationMaxMS

    -mousewheel.enable_pixel_scrolling

    -mousewheel.min_line_scroll_amount

    -mousewheel.acceleration.start

    I don't know if there's more available however, the ones I tested.

    As a result, whose entrance is the best editing to increase scrolling speed?

    This is the meaning in which you want to scroll:

    x: horizontally
    y: vertically
    z: only applies if you have a 3D capable device
    

    Normally, you would like to set the value of y for scrolling up and down.
