Abstract: A Field Programmable Gate Array (FPGA) for video processing including a graphical processing unit. The FPGA comprises an interface for receiving drawing commands, a VRAM for storing video data, a shader device configured to load a software applet into a working memory for executing the drawing commands. The shader device generates graphical elements that are written into the VRAM. The FPGA further comprises an output for providing a composed video output signal including at least one video stream and at least one graphical element associated with the video stream(s). The FPGA can be implemented in a video processing device, such as a multiviewer system.

Abstract: The present disclosure relates a method for evaluating packets of subscribed data streams comprising receiving incoming data packets belonging to a plurality of data streams; buffering the incoming data packets in a raw packet buffer; extracting the first words of the incoming data packets and forwarding the extracted first words to a packet header buffer; evaluating the first words in the packet header buffer, wherein the evaluation comprises extracting information identifying a data stream, performing a binary search on the extracted information to determine whether the incoming data packet from which the information was extracted belongs to one of the subscribed data streams, storing the result in a packet evaluation result buffer; determining based on the result whether a data belongs a subscribed stream; reading, in case the data packet in the raw packet buffer belongs to one of the subscribed streams, the data packet from the raw packet buffer.

Abstract: A switch device for connecting a plurality of field devices to one single master port of a master device, the master device providing a gateway between the field devices and an upper level network and being configured to control a communication between the upper level network and the field devices, the switch device comprising: a physical master-side port for connecting the switch device to the single master port and for establishing a master communication channel between the same; and a plurality of physical field device-side ports for connecting the switch device to the field devices and for establishing a plurality of field device communication channels between the respective field devices and the switch device; wherein the switch device is configured to transfer data between the master device (3) and the field devices through the master communication channel and the field device communication channels using a single communication protocol for an automation network.
