This interface lets you download configuration files into a Xilinx FPGA using USB 2.0 or 3.0. The firmware files with this application note are designed and tested for Xilinx FPGAs, but you can customize them for other FGPAs with a similar interface.
In addition, FX3 provides interfaces to connect to serial peripherals, such as UART, SPI, I2C, and I2S.
FX3 allows you to add SuperSpeed capability to any FPGA-based design. In most applications, FPGA acts as a master and the GPIF II operates in a synchronous Slave FIFO interface.
