• The analysis table of Boolean in FPGA

  Hi all

  Although I programmed in LabVIEW several times, I am quite a novice when it comes to programming on an FPGA, and I learned that I will (which, so far, has worked with little problem).  However, I have solved my most recent problem and more I read on the FPGA, less certain I am that what I try to do possible.

  The task is to read in a number of bits of the digital input/output lines of the FPGA and the analysis of these bits in specific words / "bytes."  For the application of the VI that I have attached, I rigged reading in a certain number of bits by providing three words of 26 bits (for a total of 78 bits) that have been defined on the front panel.  After providing the bits specified, I try to analyse the bit array in the specific words that are given by the following logic:

  1. find a start bit of 0 (false bit).

  2. once the start bit of 0 (false bit) is the word that seeks to analyze is the next 10 bits.

  3. after the start bit and 10-bit of data is a 1 (true bit) stop bit.

  4. Repeat steps 1-3, five times.

  The logic above, should be six words analyzed in total for the provided VI.  Unfortunately, I can not simply take 12 bits (1 start bit, 10 data bits, and 1 stop bit) at a time, as the number of bits of padding between successive words is variable.  The VI I provided is a version of how I proposed to perform the logic above, but I can not compile the project/VI, I get constantly mistakes "Tables to be fixed size."  To my knowledge, all the tables in the VI have been allocated in advance, and seems to be deterministic.

  If anyone has any suggestions as to why this VI is not compiled, I would greatly appreciate.  Thank you in advance for taking the time to look at it, and I look forward to resolving this issue.

  With gratitude,

  Gregory

  Unfortunately, you'll have to rework this VI to run on an FPGA.  You cannot move tables in memory in an FPGA the way you can on a PC.  You have an array of variable size as the exit to remove the table, because the entry of length is not fixed at compile time.  In addition, two-dimensional arrays are not allowed.  Remember when coding for an FPGA you actually write the material - each value in a table is basically a circuit (that's my oversimplified understanding).  The compiler cannot affect the right number of sons to carry a table if it cannot determine the size of the array.  The table is not in memory, so there is no way to reorder running.

  There are two ways you can work around this problem, which will require an iteration through each element of the input array.  You could use a FPGA FIFO and just put the values in the FIFO which are given (that is to say, in a loop until what you have touched a start bit, putting the next 10 values in the FIFO).  Then across the FIFO, possibly in a separate loop, read 10 bits at a time to get your words out of data.  Another approach is to reorganize the table as you go.  Keep track of the current location in the input array.  When you hit a start bit, away from the 10-bit (you may need to do this one at a time) to the current location in the input array, incrementing the current location every time.  When you have completed all entries, all data will be at the beginning of the table in units of 10 bits, which you can split out as needed.

• How to get the amount of memory installed?

  (It's under the Windows operating system)

  I have do a comparative analysis program for the performance statistics for some complex calculations based on the hardware.

  What is the best way to get the amount of RAM installed programmatically?

  How do I know if the OS is 32 or 64 bit?

  Thank you!

  Well, it does not resemble the Memstats VI returns the memory installed. It returns a number, but I can't match the amount of memory installed on my system. The GetCurrentPlatform seems to return only the name of the OS, not whether 32-bit or 64-bit. I see nothing in the App-> target list containing this information. At least to 8.2. Did not check in 2009.

  Define "better". Best in speed? Better compatibility on multiple versions of the Windows operating system? Best in terms of access to this information without having to delve too in all sorts of types of data Windows and DLLs?

  Would you consider .NET stand for the 'best '. If so, the amount of RAM installed can be gained from easily using the Microsoft.VisualBasic.Devices.ComputerInfo class:

  

  To determine whether your OS is 32 - bit or 64 - bit are you trying to make a distinction between a 32 bit on a 64-bit CPU vs OS a 64 bits on 64-bit OS? I know that the WMI class can be used to obtain this information, so if you try to make this distinction, you could watch the Win32_ComputerSystem and Win32_Processor classes. For example, I think that what follows is what you would see:

  OS 64-bit on x64processor:
  Win32_ComputerSystem.systemType = pc x 64
  Win32_Processor.addresswidth = 64
  Win32_Processor.architecture = 9
  Win32_Processor.DataWidth = 64

  32 bit on x86processor OS:
  Win32_ComputerSystem.systemType = x 86 pc
  Win32_Processor.addresswidth = 32
  Win32_Processor.architecture = 0
  Win32_Processor.DataWidth = 32

  OS 32 bit on x64processor:
  Win32_ComputerSystem.systemType = x 86 pc
  Win32_Processor.addresswidth = 32
  Win32_Processor.architecture = 9
  Win32_Processor. DataWidth = 64

  I've attached an example on how to access the classes with .NET. Not pretty, but not too bad either.

• Security: how to cancel 'save the analysis' obiee 11g?

  Hello world
  
  have not worked with the 11g version yet, I have to help a colleague.
  Aim: user who can do ad hoc analysis but is unable to save them.
  Can someone explain how I can revoke the privilege 'save the analysis' responses? Can not find, and I want to not meddle with the standard groups and permissions.
  
  
  That's what I did:
  -created user with 'bi writers' group
  -J' created a group 'bi authors without memory' with the option ' create as.
  
  Then I have 2 problems:
  1 al ' webcatalogs, the new group does not show
  2. I have not found the option to cancel registration in to 'manage privileges' screen.
  
  Thanx
  Sandra

  Hi Sandra,.

  they save the reports in my files or folders?

  We can restrict access to the answers/analysis directly from the Administration--> privileges to manage

  Thank you

• explain the analysis analyzed, plan implementation, the hash value code

  whts the hash value, code analysis, plan to run?
  can we see the hash value?

  The analysis is the first step in the treatment of any statement in an Oracle database. Statements are broken down into its components and so DML or DDL statement type is determined and different controls are carried out on this subject. A statement must be evaluated and validated before execution. Oracle evaluates statements for syntax, the validation of objects and the privileges assigned to the user.

  Oracle hash value will check privileges for any SQL statement, and then assigns a number called the hash value SQL for the SQL statement to check whether or not this statement exists in memory

  The statement execution plan, will select the best methods to access the SQL statement

• Edit the modules of memory in Satellite M30X 165

  The laptop has two memory modules with 512 MB of each module. I got an opportunity 1 gigabits.

  Can I remove one of the 512 MB modules and install the 1 GB module to get total 1.5 GB of RAM or need two modules of the same size memory?

  I agree with user IronMan.
  The laptop seems to support 2 GB of RAM, so the use of modules of 1 GB and 512 MB of RAM should be possible

  Get only the memory of a place as above, since Macs are picky about the memory. Another place is crucial.

  If you can't swing for 16 GB (2 X 8 GB) replace a strip of 2 GB with a key of 8 GB.

• I can't find the slot of memory for the Satellite S70-B-10V

  How can I upgrade my memory to laptop? It is not a memory slot at the bottom of the laptop.

  As already mentioned by Timox: there is no separate access to the memory locations.
  The slot of memory and HARD disk access is hidden under the hood.
  So to put level memory and other parts, the laptop must be disassembled and the bottom cover must be removed along with other pieces as ODD, battery, etc.

  It is a bit tricky, but the most important fact is that the removal of the bottom cover could void the warranty, and I guess you don t want to lose the warranty.
  Any hardware upgrade must be performed by the authorized service provider.

• Where is the support of memory on Satellite 2450-SP295

  I have install memory expansion

  Please, I beg you. Spoke Spanish. Thank you.

  First all of the questions and comments in this forum from Toshiba are displayed in English
  and I assume that all users can match only in English.

  Now to your question:
  The Satellite 2450-SP295 is not known to me, but I found some info on the Satellite 2450 - S203.
  Both units show very similar and should have the locations of memory under the keyboard.

  If you want to upgrade the memory you have first of all remove the keyboard.
  The keyboard is fixed by 2 screws that are placed under the thin cover above the keyboard.

• How to change the maximum virtual memory

  Hi, I use a laptop 1.8 GHz, 512 MB of tevra m2.
  normally used for office work and not for games,
  BitDefender Antivirus consumes a lot of memory, so be careful about the use of memory.
  so I was wondering if anyone knows how to set up the best of 'virtual memory': min and max: about 1.5 to 2 times the size of RAM?
  Thanks in advance

  Hello

  Please go to:

  Properties - "Advanced" tab - control panel in the button 'Edit' performance zone - tab "Advanced"

  You will find the virtual memory settings.
  I recommend you set the settings of "size of system managed". In this case the OS will control the value automatically.

• View the size of memory for Equium A100-233

  Hi I have laptop very an Equium A100-233.
  In the specifications, it indicates that the built-in display memory can be up to 128 MB.
  The problem is that the driver has 64 MB max.
  As the memory is shared with the system memory, I guess I do need a MEMORY larger bar, so I put a 1 GB DIMM in there now, but it still says 64 MB max.
  So is there a setting I need to change to make 128 MB?

  I also think that you have the Satellite A100-233 and not a satellite.
  I put t found any unit Equium bearing that number.

  However, the specification says the laptop supports an Intel 950GM 8 MB to 128 MB shared memory.
  Upgrade memory max could be up to 4 GB. Then perhaps you need to install more memory to use the 128 MB

  But if it is not a special option for graphics memory changes so I assume that the driver will check the value of memory.
