• Why is the FPGA Compiler server so slow?

  FPGA Cloud compiler is faster because NO servers are performing, right?
  Well, my Windows 7 PC is powerful, but no luck there!

  Total CPU utilization is never more than 25% and the total memory (including other applications) usage is less than 16%.
  Why, the compile Server uses all available resources? has been restricted?
  How can I leverage more power from my PC?

  If servers OR compile faster code, there must be a plausible explanation / reason?
  Please indicate, how to make the compile server running faster in place?

  I don't know what machines compilation cloud service works, but I do not.

  It seems that the compilation is much faster on a Linux machine on a Windows machine (I think I've heard up to 30% faster). The Linux FPGA compile server is available for LV2012. Set up a Linux machine with a clock high enough CPU and RAM speed and you will get on the fastest possible compilation with current tools.

• tables of fixed size in FPGA compilation error - how to implement a waveform control in an FPGA?

  Hello

  After being stuck for two days, please let me briefly describe my project and the problem:

  I want to use the cRIO FPGA for iterative control of waveforms. I want to capture a full period of the waveform, subtracting a reference waveform period and apply control algorithms on this. Subsequently the new period of correction must be sent again for the output module OR. If it does not work, the captured waveform will look like the one reference after several iterations.

  I am planing to create an array of size fixed for the capture and the reference waveform (each around 2,000 items for a given period). I use so 2 paintings of each elements of 2000. I use the function 'replace the subset of table' to update each element captured in the loop sampling and a feedback for each table node to keep in memory (I also tried shift registers, but then the berries do not have a fixed size any more and I can't start the compilation process).

  If I try to compile the FPGA vi, I get the following error:

  Before I added berries to my code I could compile the FPGA without problems. So, it seems that the tables are too big for the FPGA. :-(

  Therefore, I would like to ask if there is perhaps a better method to implement my problem in LabVIEW FPGA? How could avoid the tables to save my waveforms on a period?

  Thanks a lot for your help in advance.

  Best regards

  Andreas

  Unfortunately, the LabVIEW FPGA compiler cannot deduct stores shipped from berries (yet). When you create these two large paintings, you are creating essentially several registers very, very large. Just by looking at your picture, I guess that there are at least 4 copies of each of the tables.

  You want to use LabVIEW FPGA memories instead. You can create memories outside the loop and then read/write them where you are currently referencing the berries. The only change that you really need to do is to break down your treatment in scalar operations. I have attached a simplified version of your plan, I hope it helps. Let us know if you have any other questions.

  

• Question of server FPGA compile

  Hello

  I want to implement a system of compilation farm. There is only a PC development (possibly 1 later) and compiles a worker. The question is, the compile Server (one which dishes to the worker of the compilation of the tasks) possible on the same PC used for development, and in the affirmative, he introduced the bottleneck important compared to using a dedicated machine?

  Thank you

  Hi ToeCutter,

  The compile server can be on the same PC that is used for development without any problem

  ' ' ' ' Refer to the getting started with the FPGA document compile farm, available by selecting Start "all programs" National Instruments "FPGA" start-up of the farm to compile FPGA, for more information about configuring and using FPGA compile farm.

  Use "localhost" as the host name of the server for your compilations to compile.

  Compile farm server uses the same compiling installed tools (Xilinx) on your PC, but instead to directly obtain the LabVIEW project files

  It compiles the files downloaded by the user, there is no difference in performance.

  I hope that helps!

  Kind regards

• Question of FPGA compile farm 2012

  I was under the impression that my FPGA LV code can be compiled by several workers when I bought and installed the FPGA compile farm Toolkit.  What I have, however, is that each work of compilation can only be compiled by a worker.  I expect that a single compilation work can be divided by the number of workers.

  So I see that a worker of computers will compile two computers of worker work.  It's just that a worker will be compiled at the same time.

  I just misunderstand the features to compile farm Toolkit or is it an installation problem?

  Thank you

  No, a unique compilation cannot be shared between workers. Nature of the beast-FPGA "compilation" is not something that lends itself to parallelism. You have the advantage that the build tools run much faster under linux, however.

• Question of FPGA on speed

  I have as part of the much bigger problem simply multiply the elements of the two tables and summarize the terms to give a single output constant.

  There may be 100 terms mean in the table, but this test that I attach only uses 6 numbers and the same table twice for simplicity. I'm so calculate the scalar product of two vectors of surface where ' is transposed.

  It has been suggested that I shared the calculation in two so that I have summarized the first 3, i.e. 0,1,2 and 3 last, IE the 3,4,5 in parallel (as in the program). Of course, I get the same end result. Would this double FPGA execution speed because it's doen in parallel?

  The reason why I ask this question which is probably if I used a power of 2 amount of data I could divide it again and still a bit like a FFT,.

  Does make sense? or is the FPGA "unpack" the loop FOR in any case is not worth?

  the program displays the original and the split method.

  Thank you

  The side is an FPGA will give you gains of speed whenever you parallelize computation.  The downside is that you still have to do most of it.  No shipping FPGA course OR product made optimizations such as loop place (although the standard LabVIEW).  This is a dangerous operation that could increase the size of the code and FPGA programmers tend to be picky about these things.

  If you can get speed gains each time you parallelize, but you will have to do it manually.  Note If your parallel loops that access a shared resource (memory, state variables, etc.), the claim on this resource will reduce the overall speed, so you get.  Also, if you can integrate calculations in a single-cycle timed loop, you will get there, effectiveness as well.

  Good luck and have fun!

• FPGA Compilation fails because of the mistake of Xilinx

  My FPGA compiles and I cannot understand why. There is nothing crazy in my FPGA VI of really, it seems strange to have this type of problem. I can't reach the code because its owner, but it's pretty simple because it reads all channels from a single module and records them in a data FIFO. I have compiled successfully any FPGA code on this computer, so I should definitely have everything needed to compile.

  My system consists of one NOR cRIO 9030 with a single module 9220. Below is the Compilation of summaries.

  I download the latest FPGA 2014 SP1 installation and I hope that will solve my problem.

  Well I'll mend, which fixed the problem! Somewhere along the line, my install FPGA must be corrupted.

• Understanding on the 9505 FPGA VI speed control

  I was able to quickly use the 9505 Servo Drive example for closed loop control of position on the FPGA, but I can't find how to change the code to take in charge the speed control (which I need to another axis).  I'm doing my changes on the FPGA VI itself rather than on the side of RT Softmotion.

  Here are the questions I have:

  If I use the PI speed loop with my speed and a set arbitrary control speed, I see the speed stabilizes (engine power seems uniform), but I can't correlate with the other speed reference that a larger number is faster.  Speed (from the loop of the encoder) seems collating in values from 0 to 2 just on my FPGA VI (I do not understand the units, but I see my position change on my collation of encoder in thousands of pulses per second).  Why are they so different/how I have adapted my encoder speed correctly?

  Using just the delivery example 9505 Servo Drive (position control), how to set the speed of moving of the FPGA code (in interactive mode)?

  Hello

  Speed is defined through position set points. Control of the speed in the screw RT does not actually send speed commands to the reader, but sends position set points at a known rate. Given that the position set points are sent at a constant rate, an effective speed can be calculated.

  A method to do so via the FPGA would synchronize a loop in your FPGA code for the analytical engine, which has a known rate. Once this is done, you can calculate the actual speed of the engine.

• Can farm FPGA compilation split a single compilation?

• stuck FPGA compilation, no errors

  Hello

  I wrote a LabVIEW FPGA 8.6.1 program (I have written several, this is my most recent). When I run it on the development computer it seems to work fine without any errors. When I try to compile, however, it still stalls on this part:

  'Analysis of generic entity library ( Architecture).

  This isn't feeze (the compiler is always updated time and you can see it working). It just doesn't progress no further than this point. By chance, does anyone know what could cause this? I know that maybe it's a little vague, sorry. Thank you!

  Nevermind, I figured it. I had a knot of analog input within a For loop. This wire entry (i.e. given out the analog input node) was connected to a tunnel auto-index on the loop For I have just disabled automatic indexing on this tunnel and everything seems to compile fine now.

• Results of FPGA compilation and size required FPGA

  Hi all

  I currently use an intelligent data acquisition card (7853R) to generate the AO modulated on five channels to five different densities.  The modulated signal can be either: a sinusoidal signal, a square wave, or a wave form defined by the user using a single READ (40 k, points 16-bit).  The card I am currently using is ready by OR, and I am now faced with buying my own. Initially, I had proposed using the7841R, as it does not appear that we would be using one of the largest FPGAS to their full potential.  And for the most part, we are not.  We use about 6% of the slice of registers and 6% of the LUTs.  However, we use 100% of the IOBs LOCed (who previous knowledge base said that I would not be concerned with) and 96% of the RAM36_EXPs.  Unfortunately, I have no documentation on these and can't know if my code fits on most small (wx30) FPGA in the 7841R.  If I had to guess, I would say I use 96% of the RAM on the current FPGA block and my code would have hard on the smaller FPGA, as is the block of RAM available< half="" of="" that="" on="" the="" larger. ="" but,="" i="" don't="" think="" it="" is="" that="" simple. ="" does="" anyone="" have="" any="" thoughts="" on="">

  Thanks, Matt

  I know not what it is either, but you can always choose the destination in LabVIEW and compile the application. you don't need hardware for it. Try it and then you should be able to make a purchase decision. Of course, someone of OR should be able to get back to you on the definition of the attribute. or I'll just say: ask him when you call to buy the product. If you have any questions, please after return.

• FPGA compilation error

• FPGA compilation error sbRIO 9632

  Hi guys,.

  I'm trying to write a simple piece of code to send a PWM signal to a PIN on my sbRIO-9632 (starter kit 2.0) to order a servo. I used the example of 'control a servo using PWM' and my code is pretty much the same. When I try to generate/compile the FPGA VI, it stops after only 4 to 6 minutes, saying an error has occurred. The compilation appears to hang during the process of the "card".

  The example is for a sbRIO-9631 so I created a new project for my robot Robotics and changed the PIN e/s that I use (Port5/DIO9). I search through forums but cannot find a solution to this :/

  I have attached my code and the XilinxLog file with it.

  Thanks for any help!

  Hello

  Sorry for the late reply! Have you made progress?

  Unfortunately, your zip file seems to be disabled on my PC. How it has been compressed?

  So what I meant by remove the digital Pulse.vi to generate, is to see if it affected the compilation. Please see if you can compile the FPGA code with the following approach:

  Create the new project > add your target sbRIO > add the VI attached to this post to your FPGA target > compile

  I think it would be beneficial to you to see if the problem is the compilation itself or the code you are trying to compile.

  In addition, you have any another available PC? Might be a good idea to see if your code compiles on another PC.

  Please make sure you have LabVIEW Real-time and LabVIEW FPGA installed (it should come with the Robotics module, but I recommend that you check that they have indeed been included).

  If the build process fails to map no matter what you do, I propose the following: make sure that the target passes a self-test of MAX. reinstall the Xilinx tools (only if it seems that the issue is not with the code, but with the compilation process itself).

  Good luck

  Best regards
