In allusion to the requirements of real-time performance,small space,low power consumption,and large capacity of high-spinning projectile data processing and storage,a real-time data processing and storage system applicable for the highspinning projectile is designed,and a data processing and storage method is proposed,so as to realize real-time processing and acquisition for sensor data of the conventional cannonball during flight. The working environment and data acquisition process of the high-spinning projectile are analyzed to determine the data processing and storage requirements. In combination with the requirements,the dual core architecture of Cortex-M7 and FPGA equipped with the external parallel high-speed ADC is adopted to realize the acquisition and processing of sensor signals,and the large-capacity chip external Flash controlled by the highspeed FMC bus is adopted to realize the storage of processed data. On the basis of the above hardware,the synchronous highspeed data acquisition and storage method is put forward. The correctness of the system function was verified by means of the ground test of the high-speed rotary table and live ammunition flight,which has a great application value for the research of ballistic environmental force and guidenization of the conventional cannonball.
