what are the advantages using labview 8.5 with my RT-9004 controller.

[Pratima]

Hi,

           I am working with cRIO with 9004 RT controller.I am developing my application in LabView 8.2.I am using all 3 DMA FIFOs so i used 4 TCL in my RT(host) to reading data and writing in 4 sepearte binary file(on RT-flash memory-512 MB).is this recommended or will it decrease performance.I heard Labview 8.5 supports multicore programming.I dont know my RT controller has this feature or not.will i get good performance using 4 critical loops with LabView 8.5 plateform.

I think my query is clear,please reply me soon.........

Hi Pratsha,

The 9004 is NOT a multicore controller, so being able to select which core a task runs on does will not improve performance.  Also, 4 time-critical loops typically is NOT desired.  That is because time-critical means the MOST important operation compared to other parallel operations.  If all you have is 4 timecritical operations and no others, then all the loops are the most important, thus making none of them important.

A reason to upgrade to LabVIEW 8.5 with a cRIO is the fixed-point data type.  I would look into that if your interested.

Hi Specialist,

                    I understood the Multicore features of LabView 8.5.I was very excited when i see multicore term with Labview 8.5 thats why i planned to do my application in this platform.ok! what RT controllers have multicore features?I am using 3 TCL beacause I am using 3 FIFOs in my fpga to acquire data with 3 different sampling rate from NI-9233,NI-9201,NI-9237 and i want to read those fifos in my RT.and i m using polling method to read data from each fifo.please suggest me how can i acquire data from those fifos.

Hi Pratsha,

           The cRIO controllers are not multicore controllers.  Our customers that need multicore functionality for their applications use Desktop PCs with the RT operating system installed.  If you have already purchased LabVIEW RealTime you can use our utilities to reformat and install the RT operating system on another computer of your choice.  Have a great day.

Don't forget the PXI controllers like the 8106 have dual core as well.  Very similar to the desktops 🙂

hello,

                How can i make my desktop as RT controller,i mean what are the steps to make my PC asontroller?

Have a look at the Knowledge Base:

This one talks about PXI, but it has links at the bottom which could be useful:

Here is another link:

Above is a pdf that may be interesting.

Hello,

           Thanks,this seems good stuff to make PC as RT controller.
