摘要
设计了一种基于ARM处理器和现场可编程门阵列(FPGA)的弹丸测速系统。充分利用FPGA的高速并行处理能力,进行多路触发电平的捕获,利用ARM进行逻辑控制与数据存储交互。实验结果表明:系统测速的精度在2%以内,满足实际工程应用的要求。
A projectile velocity measurement system based on ARM processor and field programmable gate array(FPGA)is designed.Make full use of the high-speed parallel processing ability of the FPGA to capture multi-channel trigger level,and use ARM for interaction of logical control and data storage.The experimental results show that the precision of velocity measurement of the system is within 2%,which meets the requirements of practical engineering applications.
