High-Precision EMV Measurements
Every consumer electronics product has to comply with standards for electromagnetic radiation to ensure that any emitted radiation is not harmful to those who use it. The same principle applies for industrial electronic devices; there are strict rules regarding the amount of emitted radiation which is permitted. In both cases, the device’s manufacturer must prove that radiation emitted is within the allowed range. A more precise measurement of this radiation means that a smaller margin of error has to be applied and thus makes it easier it to meet the certification criteria.
We were approached by a customer with the aim of building high-precision measurement equipment for electric and magnetic fields for certification purposes. The baseboard that carries the electromagnetic sensors and all required analog electronics is being developed by the customer, and is equipped with a small, custom FPGA module. This module, as well as the FPGA firmware running on it, is being developed by Enclustra. The firmware contains a wide array of signal processing to correct any measurement distortions caused by the analog electronics, as well as complex data-logging logic and an interface to a host PC, where the final data processing is applied and the certification criteria evaluated.
Thanks to the use of ready-to-use Enclustra IP cores in this project, the development effort has been greatly reduced: FPGA Manager USB 2.0 is used for the communication with the host PC, and the buffering logic is mainly implemented using the Stream Buffer Controller IP Core.
Zynq UltraScale+ drone control
The official term is unmanned aerial vehicle (UAV), apparently, which is a bit of a mouthful, so we prefer to say drone. In any case, we developed a controller for a UAV (drone) for a customer using a Xilinx Zynq UltraScale+ SoC, whose CPUs implement the position control as well as tracking of the flight trajectory. The sensors and actors are attached through the FPGA logic; the number and type of these interfaces vary greatly with the type of controlled vehicle, so all of these interfaces are dynamically configurable.
The controller also supports redundancy, by having two parallel flight calculator units supervising each other. Should the currently active calculator fail, the reserve unit takes over all tasks autonomously. Aside flight control functions, the controller prepares and compresses a Full-HD video signal (HD-SDI) from a camera for transmission over radio.
The first SO-DIMM Zynq UltraScale+ Module has landed
We just received the eagerly expected Mars XU3 module. Rejoice guys, because the Mars XU3 module offers really cool features on a very tiny space! It's built around the brand new Xilinx Zynq UltraScale+ and offers up to 154,000 systems logic cells, 108 user I/Os, 6 ARM® processors, a GPU, up to 4 GByte of ultra-fast DDR4 SDRAM, 64 MByte QSPI flash memory, 16 GByte eMMC flash memory and Gigabit Ethernet and USB 2.0/3.0 ports.

Ultra fast SoC design with Visual System Integrator
Visual System Integrator, from System View is a graphical extension to the Xilinx® Vivado® suite for the development of complex embedded systems. The tool supports most Xilinx FPGAs and SoCs, as well as Windows and embedded Linux. After rendering the hardware platform setup, the tool automatically generates the needed interconnects: PCIe, AXI-MM, AXI-Stream, Ethernet and Aurora interfaces are all supported.
The first official release of VSI is available now for evaluation – a quick search online will lead you to a few videos showing the graphical user interface and example applications in action. The graphical user interface the system designer, to drag-and-drop functional blocks between CPUs and FPGAs, and generate the new bitstreams and binaries with just a few clicks.
Free seminar: Getting started with Xilinx Zynq SoC
Enclustra and Avnet SILICA are arranging a free seminar on the SoC design integration.
Don’t miss how engineers from Avnet SILICA and Enclustra illustrate how you can utilize the full performance of a SoC, even with minimal VHDL and FPGA know-how. If you’re working with microcontrollers, DSPs, SoCs and FPGAs – you should join us! Learn for which applications SoCs are good for, how you can shorten your development time, which tools are required and many more interesting things.
