I received an email from a reader asking me what controller I am using, so I figure I would make a new post with this information: (All links open in a new tab) PXIe-8105 Embedded Controller https://www.ni.com/en-us/support/model.pxie-8105.html PXIe-1062Q https://www.ni.com/en-us/support/model.pxie-1062q.html PXIe-6592R https://www.ni.com/en-us/support/model.pxie-6592.html And a picture (why not?):
So first off, I have merged my code to master, see it here: https://github.com/fpganow/MicroBlaze_lwIP And while I work on updating the README.md file, here are 2 slides for you to look at: So, if you have the appropriate NI hardware, you can clone down this repository and run 1 TCP and 1 UDP session to … Read more
As I was traversing my mental decision tree using a depth-first search model of digger deeper and deeper in to the lwip TCP/IP source code, I thought to myself that I should go back up the decision tree and take a deeper look at the tcpdump output. It turns out I was setting the source … Read more
What I have working right now: A UDP packet enters the FPGA via the 10 Gigabit PHY that is connected to the FPGA. The 10 Gigabit Ethernet MAC running on the FPGA consumes the Ethernet Frame and passes it in to a c++ application running inside the MicroBlaze Processor. The MicroBlaze Processor is running a … Read more
The National Instruments “LabVIEW 2018 FPGA Module Xilinx Compilation Tool for Vivado 2017.2 – Linux” is only officially supported on Red Hat Enterprise Linux and CentOS. CentOS is basically a clone of Red Hat Enterprise Linux, also known as RHEL. I like to joke and call it R-HELL. The reason is valid, Red Hat Enterprise … Read more
So it appears to me that Monero/CryptoNote mining has gained a lot of popularity lately, and this has led many people to this website. Let me note that LabVIEW FPGA is a proprietary tool that comes with a 30-day Evaluation. After that, you have to spin up a new virtual machine and reinstall LabVIEW to … Read more
If you purchase the National Instruments PXIe-6592R Board, retailing at $12,197.00 USD, I guarantee that you can run an FPGA accelerated 10 Gigabit network card in as much time as it takes for you to synthesize your code! Call Now, the number is 1-900-XXX-YYYY. Batteries not included, strings attached. But seriously, I have just cleaned … Read more
I have wired up the components of my 10 Gigabit FPGA Accelerated Network card with great care, and I decided to have my “tester” application skip the lwIP stack and to pass the received packet directly to the host for testing/verification purposes. Everything was checking out fine, the LabVIEW code looked flawless, the interface to … Read more
So here is the most simple, FPGA-based Network Interface Card that I know of. This application will start Port 0 of the 10 Gigabit Network interface that is provided by the PXIe-6592R (http://www.ni.com/en-us/support/model.pxie-6592.html) board by National Instruments, and will allow you to do any of the following: Check if any new ethernet frames have been received, and … Read more
I am getting real close to finishing my proof-of-concept FPGA-based network card that is based on the PXIe-6592 National Instruments Board which uses the Kinex-7 410t FPGA chip by Xilinx, and has 2GB of DDR3 RAM. Using the Arty Arix board, I was able to make sure that the MicroBlaze code running the lwIP TCP/IP … Read more
