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
What is the product of 0x9D0BF6FDAC70AB52 and 0x6408F6540A1384CB? Well, according to LabVIEW for Windows, the answer is 0x2D90DE07C0C42206. According to C++ on OSX (without any optimizations, usage of Intel Intrinsic functions), the answer is also 0x2D90DE07C0C42206. The real answer is… 0x3D5E2BF7DCBCA6622D90DE07C0C42206. How do you get this number? You have to use compiler intrinsics, or calculate this value … Read more
So I wanted to implement a simple, stripped down version of the open-source lightweight IP stack “lwIP” (https://savannah.nongnu.org/projects/lwip/) inside my LabVIEW FPGA project that I can handle TCP and UDP data streams. I do not have a lot of experience with this, and I found that building such a project inside Vivado would take around … Read more
