-flink can be read as //fast link// or as the German "flink" meaning fast. It enables any processors to communicate with an external FPGA over a serial interface, e.g. PCI or SPI. The FPGA may contain several blocks such as counters or pulse-width modulation. Such blocks are extensively used in robotics for control applications. +flink can be read as //fast link// or as the German "flink" meaning fast. It enables any processors to communicate with an external FPGA over a parallel interface (e.g. PCI, EIM, LPB) or serial interface (e.g. SPI). The FPGA may contain several blocks such as counters or pulse-width modulation. Such blocks are extensively used in robotics for control applications. \\
