A Data Concentrator for an avionics network, comprises of input/output interface (I/O) for connecting one or more input/output devices and remote processor. The Data Concentrator Units (DCUs) collect discrete inputs, analog signals, and digital data from sensors and equipment throughout the aircraft, then convert them to digital format for streaming over the data bus. The DCU is interfaced to the other systems by way of the aircraft digital data bus and is usually the data hub for most of the avionics equipment. This paper deals with the design of Virtex-6 FPGA (Field Programmable Gate Array) based Data concentrator card. Since it is based on FPGA the Data Concentrator is flexible, reconfigurable and high performance device. The FPGA can be programmed to the required functionality & only the minimum information will be passed on to the computer, thus reducing the load on the computer. The Schematic design is carried out using OrCAD tool.
