Abstract


With the wide application of UAV(Unmanned Aerial Vehicle) in the fields of both army and commerce, the flight control computer is facing more austere challenge. However, we have decided to suggest a scheme that is based on DSP and FPGA by analyzing the advantage and shortage of the present flight control computer of mini unmanned helicopter and combining the strongpoints of DSP and FPGA.The dissertation firstly summarizes the rough design scheme of the system based on DSP and FPGA, and DSP is mainly used for the computing of the complicated arithmetic, such as navigation computing, control discipline computing and so on during the flight,while FPGA is mainly used for the bottom data processing and logic control, for instance, implementing the muiti-serial communication and interrupt control. Then, we gave the indexs to be designed, and we have introduced the hardware and software design of the system detailedly. The hardware design containes the following:power design, the DSP chip and its expanded stored chips circuit design, the FPGAchip circuit design, the GPIO circuit design, the A/D convertation circuit design, the muiti-serial communication circuit design, the sensor circuit design and so on, and the software design containes the parts, which are mainly the flight control software, the muiti-serial communication logic,the interrupt control logic.The most different feature of the design compared others is that it has not only achieved the logic control, but also has achieved the function equal to the ASIC chip. So it manages to make the circuit much more simple, the volume much smaller, and need less power consumption, then it has improved the embed performance of the flight control computer dramatically.
