Application of FPGA in Small UAV Autopilot Based on Embedded Linux System

The application of compound mode of the "xscale+FPGA" in the small UAV autopilot was presented, in which the xscale chip-PXA255 of Intel was adopted By analyzing the process of the chip XCS30XL-4VQ100 working on the FPGA and the application of the embedded Linux system, the FPGA driver was designed. Finally the application of FPGA driver in the autopilot was introduced.
