• Trigger two FPGA instances at the same time

  I have a basic FPGA code that transmits the bits of data on a serial (RS-485) bus, the code is written so that it expects in the first State of a machine to States in a single-cycle timed loop.  After a certain trigger, he begins to read a FIFO containing data and sends the data on a line of Tx.  It does this until all bits are send and then it goes back to the first State to wait for the next trigger.  The relaxation is necessary because windows must fill out first before the FPGA FIFO can start sending.

  I need two instances of this code runs, because I have two buses of com (one is redundant).  So I use the FPGA code as a Subvi and I wrote a main FPGA vi to call two separate instances of the Subvi in parallel.  A regular window vi wrote on the FIFO for bed FIFO for Rx and Tx.  No problems so far.

  The thing is I start two transmissions in 200nS of each other (Yes, nanoseconds).  Windows will write two FIFO in parallel, but the timing is 4uS apart, too long.  I tried implementing a Boolean flag in the Subvi FPGA, but windows can not write directly on the control of Subvi.  FPGA won't allow (the Write function is grayed out).  I tried to use a FIFO for a flag, but the problem is a race condition.  One of the instances is first read FIFO and he destroy.  The other can't read.  I need a common trigger point to be used by the two instances of Subvi.

  My final solution was to use a memory in the Subvi FPGA and digital control in the main FPGA vi.  Windows write in numerical order, it may because the control is in the main FPGA vi.  Inside the main FPGA, I run a timed loop that looks for digital to be zero.  If so, it writes the value into the location of the memory used by the Subvi FPGA.  After awhile, the principal wrote a zero back to memory to prevent the Subvi is restarted, as well as to write a zero for digital to reset.  This repeats, waiting for windows to write in digital again for the next transmission.

  I had to do it this way because sometimes I want to pass on the bus, and sometimes just one or the other.  Numeric values are used to determine which to pass on.  Now, the transmissions are starting to almost exactly at the same time, 1 or 2 nanoseconds apart.  But the trigger process seems very silly to me.  I was wondering if there is a better solution.  I'm pretty new to FPGA.

  Basically, I did the same thing using FPGA memory.  Windows I am writing for a digital control that resides inside the main FPGA vi.  In the main FPGA, I write in the memory.  Inside the Subvi FPGA, I read the brief and decode the value to use either one or the other or both buses.  After fool with it for awhile, because reading Memeory needs to use a shift register (probably because it takes a whole cycle of clock), I had to work.  The two bus trigger at the same time.  I guess it's not really important if I use a FIFO or if I use the memory.  The main problem is that I write Windows at the hand of FPGA, then the hand of FPGA for the Subvi FPGA.  Then the time is right for what is the Subvi is.

  There are some advantages to the use of two FIFO on your approach.  First of all, you don't have the change of register for the memory location.  Secondly, we should not worry that VI is responsible for compensation to the memory location, or do, you run the risk that one of your subVIs run twice, or not at all, if the memory is not erased at the right time.  Perhaps most important, you'll save yourself space on the FPGA because you will not need arbitration - the additional code that is added when two parts of the FPGA try to access the same resource at the same time.  In your case, both instances of the Subvi access the memory block at the same time, so the FPGA compiler adds additional logic to avoid conflict.  If only read you the memory block in one place and just write it in one place (reading and writing can be different loops where subVIs) there is no need for arbitration.  Using two FIFOs, you can keep independent and avoid the conflict resolution code.  See the help for the "arbitration" for more details.

• Can we have two running instance of SST in a box

  Can you have two running instance of SST in a box with a single installation of server of OSH.
  Something like several instance of apache running with the help of various conf for each files.
  
  -Ram

  There are certainly two instances to it.
  Let me be clear. two parallel proceedings of OSH can be run simultaneously on the same machine.

  However, don't tell you about your needs of test and production environment. Obviously, you can't run "a test OHS and OHS server production running in the same m/c with OHS reinstall them. that cannot be done in any component. can you run "an intermediate test and another intermediate production without reinstalling a middle layer"? certainly not!

  Read about the environments of test and production for applications first, and then read how it can be implemented in the Oracle Application Server Administrator's Guide for your appropriate version of the OAS.

• How to install two operating systems on a single computer

  How to install two operating systems on a single computer, xp and windows 7... ?

  Hello

  Thank you for contacting Microsoft Community.
  For the installation of two Windows OS (called Dual Boot), you first determine what exactly the BONES. Based on this, you can proceed to install the oldest operating system first, then installing the latest OS. Here, in your case, Windows XP first and then Windows 7.
  If you change the order, the latest version of Windows will not work correctly.
  In addition, you can use Virtual PC or VMware to use Windows XP in Windows 7. Windows XP Mode is another version of Microsoft which allows you to use Windows XP in Windows 7 through Virtual PC. You can download Windows XP Mode from here:
  http://www.Microsoft.com/Windows/Virtual-PC/Download.aspx
  To install Windows XP Mode, you must have Windows 7 Professional or higher, with hardware virtualization enabled in your PC (you should check in the BIOS of your PC). If you prefer Windows XP Mode, you don't have to install Windows XP in the above mentioned way. It installs like any other program on Windows 7.
  Note that if you have Windows 7 Edition Home Premium or lower edition, you can try Windows XP using Virtual PC/VMware or dual-boot.

• two column values in a single column

  Hi guys,.

  I have a requirement that i want to be viewing the two column values in a single as column... values year & product will be exposed in a unique column values

  Kind regards

  Sree

  Karthickumar Pillaiyarsamy yours is a database, in OBIEE is similar with some limitations...

  Sree! you have 2 ways to do this: by using the CONCAT function or the | operator, examples here are 2 concatenating year, a space and production:

  "Time". "" T05 annually name | ' ' || ' 'Products ' '. Product P1.

  CONCAT ("Time". "T05 per year of name', CONCAT (" ","Products".)" P1 product"))

  CONCAT in OBIEE accept only 2 params, so you if want to add a space between the 2 items, you must nest your function call.

  In case your year column is a number, you can convert it to a string using CAST ("your column" as VARCHAR (10)).

• Upgrade of two DB Instances with an ORACLE_HOME

  Hello

  Upgrade 10g and 11g on the BSG, an ORACLE_HOME and two DB instances, i.e. TEST & PROD.  I'm confused (issue actually maybe nonsense).

  I call DBUA twice for each DB Instances of the NEW_HOME?

  We have RHL5, where should we go for RHL6 your friendly opinion? But so that maybe it will be installed on the new machine and then export/import process will be adopted for database schemas, isn't?

  Thank you very much.

  Kind regards

  Yes, you will need to run dbua twice... once for each database.

  Regarding RHEL 6.  You can install on a new computer, then export/import...or

  (1) if the database on separated then drives clone disks at the SAN level before submitting to the new host.  You will need to re - install or clone the records containg the oracle_home as well.  Also the oratab and oraInst.loc files.

  (2) make a duplicate RMAN

  (3) closing the db and copy all files across to the new host, if the database is located on a file system.

• two flash disks in a single disk group vsan

  Every morning.

  We had our second ssd flash not to shoot the entire disk group in vsan, not a problem all the resynced and recovered ok.

  I know that we can make groups of multiple discs for each host with its own flash ssd by group, my question, do we put two SSD flash in a single disk group? If so, if one of the two breaks down the entire disk group go offline? or will she continue to work ok until these two flash drives don't?

  Thanks in advance

  Nathan

  Band 2 will improve performance, the FTT2 will lower write back-end IOPS / s (perhaps a problem, perhaps not according to the back pressure and filling of the cache). In theory, it could improve read performance cache miss, but between the CRA, the system cache read-ahead for a absences from the cache and all the rest I do not expect much.

  Small groups of disks, etc. more flash. I would recommend you start observer VSAN and watch your hit rate Read Cache and see if another groups of disks (and Flash) would be a good idea.  You tend to get diminishing returns, trying to push beyond the 90% cache hit rate

  To keep in mind that, unless you have a balancing really bad object (it would take much effort to be honest attention creating VM and deletion and then affecting the PAF policies to create) you should see a heavy a lot to rebuild many (IE when a disk or group of disks is lost the pairs of mirror for these objects will be scattered across the cluster and they will rebuild in) free space of all other disks until mirroring policy is armed).  Keep in mind that the objects is already memorized block in new components never 256 GB (by default). Because of this design as the cluster becomes larger and more areas of failure (host, disk groups, readers) ads you expect actually rebuild performance better!

  Have you experienced problems of performance on your reconstruction, and if so what are your flash/disc types and make the model of your server HBA etc.?

• Should there be two active instances of Adobe Flash player when using Firefox for windows?

  Firefox (35.0.1) used my resources to i7 CPU like crazy lately, slow down the loading of the page, scroll, etc. I am running windows 8.1. When I went to Task Manager to see what was causing the slowdown, Firefox took 44.8% of my CPU, and I noticed that there two instances of Adobe Flash active at the same time when I'm on enough image/video heavy pages like Salon.com. These two took about 5-10% of CPU. Then came in the container for Firefox which was an increase of 2.4%. Is this normal?

  IF you have more than one plugin flash on a Web page, this is normal.

  • Use the Profile Manager to create and delete profiles Firefox
    (Probably the simplest method to create new profiles.)
  • http://KB.mozillazine.org/Using_multiple_profiles_-_Firefox
  • http://KB.mozillazine.org/Opening_a_new_instance_of_your_Mozilla_application_with_another_profile
  • http://KB.mozillazine.org/Testing_pre-release_versions#Installing_multiple_versions

  With the help of several profiles is not something that yell us on this forum. This is I think seen as too advanced. But there is no certain dangers that you may accidentally delete profiles for example. It is however possible to backup profiles manually and that can be a good precaution to take. I strongly suggest you to follow this good practice (at least until you're competent enough to manually recreate and modify profiles)

  1. Used to use the slots offered by Firefox
     It is easier and safer
     • Always use an empty folder
       Other subjects disappear when the profile is deleted
     • To nest within the other profiles
       As stated above, remove mother, lose the child also
  2. Do not rename the profiles of school boards
     Confused, the profile names and folder names mismatch
  3. Do not delete the profiles of school boards
     Just remove shortcuts if it is not in use. Remove the evil and you lose cutlery, passwords & bookmarks etc.

  Uses of several profiles include

  • Trials, with own or temporary profiles
  • Different users, or the type of different work in the same OS account. Which may include different bookmarks files and/or a different set of addons.
  • Running multiple versions of Firefox and/or multiple instances of Firefox at the same time.

  There are other methods of creating profiles, but the best is probably to use the built-in Firefox profile manager.

• Satellite L50D-C-18J - two modules of RAM but single track only

  Hi all

  A few days ago I got the Toshiba Satellite L50D-C-18J with A10 - 8700P AMD processor.

  Factory 1 with 8 GB (DDR3L 1600 MHz) memory module are installed. According to various tools (AIDA64, HWInfo64, CPU - Z), the memory will operate at 668 MHz, that is to say 1333 MHz mode.

  The free memory slot I have with another 8 GB DDR3L held at 1600 MHz (with the same memory timings, but other manufacturers). The Bank will continue to operate only in single channel mode and not in dual channel mode. The A10 CPU should support.

  I have installed the latest version of the BIOS.

  We have an idea of how I have the dual-channel mode and can set the frequency of the memory? In the BIOS, there is unfortunately almost no parameter or someone has the same laptop model and with it dual-channel mode is running?

  Thanks and greetings

  Mario

  Hello. Another manufacturer is not a problem.
  You should check the following:
  (1) make sure that the two RAM modules operating at 1.35v. Search the Internet, what should be the supply voltage of the RAM you have installed. If this does not work at 1.35v then that's the problem.
  (2) whether these RAM modules supports ECC. If one of your RAM supports ECC and the other is not, that's the problem.

• Two concurrent instances of Skype running on Windows Phone 8

  On my Windows 7 Desktop (and before that, Vista), I have 2 instances of Skype running for I can get calls on my staff or my Skype business account.

  I have a 1520 Lumia and installed Skype. I can connect with either an account or another. Ok. But it's either one or the other. Can I have 2 instances of Skype running at the same time then the two are active - or on the desktop of my PC?

  You can not. No matter what application you click the icon on your phone will take you to this application. Don't start a new one. Skype would support tabs or double accounts. It would be a very good idea and functionality.
  
  Either way, you are running the latest version? Your incoming calls are still ringing on your phone while she is asleep in eve?
