Design of Hardware Platform for Flight Control System Based on DSP and FPGA

According to multi-interface communication,lower power,small size and low cost demands of a particular airship flight control system,a hardware platform is designed for flight control system based on Digital Signal Processor(DSP)and Field-Programmable Gate Array(FPGA). Firstly, The whole hardware structure of the system is introduced. Secondly,the interface resource module and power module is designed. Finally,hardware debugging and integrated test platform building are finished,so that hardware properties and interface functions are validated. It has been proved that, hardware interfaces can work together smoothly and data processing performs very well. What's more, power consumption and development costs are controlled to be low. In a word,the hardware can meet work demand of flight control system.. The hardware platform implemented by specific circuits will be widely used in navigation and monitoring fields. More ideas will be provided for the future design of flight control system.
