For video walls, video streaming is typically handled by a video controller that buffers a video stream from standard interfaces such as HDMI or DisplayPort into a frame buffer and then transmits it via Ethernet to the video wall.
For such a video controller, we took on the system development at the SoC level, including FPGA design, Embedded Linux, Linux drivers, and a userspace application for control and diagnostics.
For a fiber optic extender, we developed the software for a Cyclone V SoC, which combines both FPGA and processor.
The FPGA transmits Ethernet, USB, and a real-time control channel over a 400 m fiber optic link. The SoC processor runs on an embedded Linux created with Yocto, enabling flexible and reliable system control.
For the testing and validation of LED headlight control units, we have developed several modular control unit testers that capture and analyze data traffic between control units and headlights, and enable targeted fault injection.
A Qt-based application for visualization, along with integration into CANoe, enables convenient operation and comprehensive analysis.
The TPS92662 is a powerful high-brightness LED matrix manager for LED headlights. It enables efficient control and monitoring of LED arrays in modern vehicle lighting systems.
For easy use and analysis, we have developed a dedicated TPS92662 monitor. It allows simultaneous logging and configuration of UART channels. The monitor consists of a hardware adapter and a CANoe integration, significantly simplifying error diagnostics, monitoring, and control of the LED matrix.
For a BLDC motor, we developed a motor controller based on a Xilinx Zynq 7000 SoC. It combines sinus commutation, a positioning system, and FPGA-based FOC control with an embedded Linux application for configuration and monitoring.
In LED video walls, the brightness of the LEDs is controlled via PWM, which can cause high current spikes when multiple channels switch simultaneously.
We developed a spread PWM that distributes the currents evenly, ensuring a stable power supply.
We developed a PCI card designed for the evaluation of FPGA-based signal processing algorithms, supporting various analog-to-digital converters as well as copper-based data transmission methods, such as Ethernet and RS422, over distances of up to 200 m.

TV headends are used to feed both analog and digital television into cable networks. Their primary function is to convert television signals from any source (satellite, terrestrial broadcasts, or radio) into cable-specific formats.
For such headends, we have developed FPGA designs and implemented their control via microcontrollers.
