Design of Real-time recording missile system based on FPGA and ADS8568

Considering the increase of dynamic acquisition parameters,miniaturization of shell,and deterioration of test condition,the paper designed a miniature analog signal acquisition and storage system based on FPGA and ADS8568,chose XC2S30 of Spartan-II as the core processor,and introduced the design and realization method of the real-time recording system in detail. Tests verified by gathering and analyzing the output information from MEMS gyroscope under different rates by the three axis position and speed swing turntable showed that the analog signal acquisition and storage system is feasible and effective. The system provided a method of engineering applica?tion for multi-channel analog signal acquisition and has a certain value in engineering.
