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
So after some serious debugging, editing, and regenerating of the bitstream, I was able to send out an ARP response from the FPGA to my linux server, and for my linux server to send a UDP packet in to the MicroBlaze. This was all verified via UART debug statements. Now while I work on cleaning … Read more
Working from scratch, I created a LabVIEW FPGA project that imports a MicroBlaze design that communicates with LabVIEW via a UART, and has the ability to change the elf file in a much shorter time frame than before. I did this by adding the MicroBlaze to the project after it had been exported to Vivado, … Read more
Before I go any further and start wiring up my code to use the lwIP on the embedded MicroBlaze, I will need some sort of better method of debugging. All code that I have implemented that uses a MicroBlaze processor via the Xilinx tools makes use of the UART to send and receive standard input … 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 normally avoid shop words or “corporate speak” because I feel it dehumanizes us, but sometimes these phrases are necessary. So here is the “30,000 foot” view. And please pardon the appearance of my flow charts and diagrams, I am not a graphic designer… All images open in a new tab, so just click on … 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
The 10 Gigabit MAC/transceiver gives me 64 bit data words. I currently think I am giving and getting 64 bit data words, but I am really only using 32 bits. I came to this conclusion after I tried reading a 64 bit word and saw the data was simply two repeated 32 bit words. Additionally … Read more
