Stand-alone digital real-time image processing board based on an FPGA

In this paper, a stand-alone digital real-time image processing board based on an FPGA is presented. In other words, the main processing of the digital input data is done in an FPGA. Analog signals up to a frequency of 40 MHz and digital signals up to a frequency of 80 MHz can be processed The sampling rate of the analog-to-digital-converter and the FPGA can be configured in such a way that particular signal characteristics (e.g. frequency range) can be taken into account. One of the main advantages of the board is its ability to restart the FPGA without the need of an external host computer.
