Best way to transfer single point data between loops on FPGA

Hi,
    I used quite number of loops on FPGA and need to transfer single point datas between loops. Only the current value of data is needed so buffer is not necessary. I don't want use target scope FIFO since it require minimum 21 elements and I only need the current value. Is there other way other than local variables?
    Thanks for help!
    Regards,
   Tom

Hi Godel,
Since this discussion thread is over 3 years old, it would be better to start a new thread with your specific questions to get quicker help.
I did a bit of research on your question, and found this helpful White Paper (http://www.ni.com/white-paper/7727/en/) that discusses the resources used for components in LV FPGA code. For local variables (although it depends on hardware), it looks like it uses Flip-flops and LUTs.
As for using local variables with different clock rates, I found this KnowledgeBase article that might help shed some light on your question - some issues can arise from using them with more than one clock rate (http://digital.ni.com/public.nsf/allkb/C683585460E88508862570D1006B7434)
Hope this helps! Again, if you have follow-up questions, I would definitely recommend creating a new thread

Best way to transfer internal HD data in Mavericks to Mac with Yosemite ?

Hello,
I'm using a 2007 iMac with Mavericks and will be getting a new one which will presumably come with Yosemite installed. What's the best way to transfer all the data from my internal HD on the old system, to the new one ?
I use SuperDuper to make backups to external HD's, so if I make a bootable copy of the mac HD to an ext HD using SuperDuper, will everything function fine despite the different OS's ?
Thanks,
Matrose.

You can make a bootable copy of your system now, but you won't be able to boot from it with the new computer. They are not usually backwards compatible with the OS. But when you first boot into the new system, use SetUp Assistant to migrate the data from the cloned copy. That will work just fine.

Best way to transfer data between loops in FPGA VIs

Hi,
I'm using a FlexRio Board PXIe 7962, with an I/O module 5781.
I've set the Top level Clock to 80MHz (Base Clk 40M), and I'm implementing two loops in the FPGa VI: In the first one, I'm using a SCTL (20M) where I'm getting Digitized Data (1.5MHz) from the NI 5781, then multiplying it by a DDS Signal (1.8MHz), then I'm filtering (band-pass around 300kHz)) the product.
My question is: If what I've implemented is correct, what is the best way to transfer the first loop data running at 20MHz, to the second one running at 1MHz ? (without loosing Data of course since the signal interest is at 300kHz)
and similarly : what is the best way to transfer the second loop data running at 1MHz, to a Host VI ? DMA FIFOs?
Thank you in advance,
Zouhair

I've set the loop timer in the first frame to 4 clock ticks of 80MHz, so I imagine that what follows should not work under 20MHz, Am I mistaken?
Yes you are. That SCTL will execute in the 20MHz clock time. Everything else in the loop is just adding to that time.

Best approach to transfer and transform data between two Oracle Instances

Let me first preface this post with the fact that I am an Oracle newb.
The current problem I am trying to solve is how to quickly transfer data from a customers legacy database into a new normalized destination that is modeled differently than the legacy data. So, the data not only has to be transferred, but also transformed (into normalized tables)
We have discovered, the hard way, that reading the data using a C++ application and performing inserts (even with indexing and constraints disabled) is just way too slow for what we need. We are dealing with around 20 million records here. I need to determine what the best approach extracting this data out of the source and inserting it into the destination. Any comments or tips are greatly appreciated.
Note: I have read about SQL*Loader and mentioned it to management, but they seem resistant to this approach. It's not totally out of the question though.

Oracle has a lot of technologies that fall under the general heading of "replication" to choose from. Going from a database to a flat file and back to another database is generally not the most efficient solution-- it's generally much easier to go straight from one database to another.
Oracle provides materialized views, Streams, and Change Data Capture (CDC)-- any of these would be able to give your new system incremental feeds of data from the old system's data and could be used by whatever routines you write to transform the data between data models.

Best way to transfer XML based data

All,
I am looking for the best possible way of transferring XML based data from a server to a web based client.
XML file is generated on server and its size is massive. I am looking for all possible alternatives and possibly the best way.
Could it be AJAX, SOAP, parsing through a servlet, creating value objects?
I appreciate all inputs.
Thanks,
S.

Best way to transfer data to new internal hard drive

Hi,
I just got a new internal hard drive for my macbook and I'm trying to figure out the best way to transfer all the data from my old hd to the new one. Basically, I would just like to make an exact copy of my old hd and put it on the new larger one. Thanks for the help.

Will I simply be able to do a firewire transfer on the new internal HD is installed
Yes. Use Carbon Copy Cloner with the sopurce and destination volumes reversed after installing the new drive.
Additionally do I need a bootable copy of OSX on my external HD to do the transfer?
Yes; the clone can act as this copy. If you copy everything with Carbon Copy Cloner, you will be told whether the drive will be bootable or not prior to the clone.

Best way to transfer data between loops?

Hi, whats the best way to transfer data between loops(state machines, regular while loop etc) in labview. For so many years ive been using local variables but these can cause race conditions. Anyone advise?
Stu

It depends one the structure of the loops and how they need to exchange data (unidirectional, bidirectional, broadcasting).
The simple case of one loop passing data to the other loop: producer/consumer design pattern using a queue
If the structure already contains an event structure: User Events
The way I code is documented in my community nugget on events
I often mix this with producer/consumer.

What is the best way to transfer my date from my old iMac to my new iMac?

what is the best way to transfer my date from my old iMac to my new iMac? I don't have a time capsule, so I cannot use time machine.
thanks

Your best bet by far is to use Setup Assistant when the new Mac first starts up to transfer directly from the old one.
It's similar to Migration Assistant, but doing it that way will avoid having an extra user account.
Either way, you can connect them via FireWire, Thunderbolt, or your network, but avoid wireless if at all possible. You can connect both to your netwrork via Ethernet, or put a single cable between the two.
See Using Setup Assistant on Mountain Lion or Lion for details.

Best way to transfer video between iphone and mac wirelessly?

Please suggest me the best way to transfer files between mac and iphone wirelessly.Mainly for videos.

If you want to transfer photos and videos from the Mac to the iPhone (but not in the other direction) you can use iTunes and sync via wi-fi: http://support.apple.com/kb/HT1386
If you want to wirelessly tranfer videos in the other direction you may want to look into a 3rd party app such as http://www.photosync-app.com Note that I have not used that app so be sure to investigate others as well.

What is the best way to transfer data from a PC to an iMac?

What is the best way to transfer data from a PC to an iMac?

If you know how to set up a computer-to-computer Ethernet network, then you can give that a try, but a hard drive will be faster than Ethernet unless you don't have a lot to transfer.

Best Way to Transfer Data

My 5 year old iMac recently died. I just purchased a new one and it arrived today. I have time machine back ups from the old iMac. Mt question is what is the best way to transfer the data from my time machine back up to my new mac? Should I use time machine or should I use migration assistant?

When the Setup Assistant on the new one you will be given an opportunity to restore from a Time Machine backup. If you're out of the Setup Assistant then use Migration Assistant. Be sure you have your TM backup drive connected.

What is the best way to transfer my iphoto library from old imac to new imac. both have iphoto 9.2.1

What is the best way to transfer my iphoto library from current imac to my new imac. Both imacs have iphoto 9.2.1
os on old imac is 10.6.8. os on new imac is 10.7.2. I want the albums and events to stay intact. I have 4500 photos and 79 videos. 14.9 gb. looking for some advice here. Thanks so much.

Connect the two Macs together (network, firewire target mode, etc) and drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac and it will open the library and convert it as needed and you will be ready move forward.
