FPGA在新型激光光幕靶中的应用

结合坐标采集和处理在新型激光光幕靶中的应用．针对传统激光光幕靶处理器I／O紧缺、处理速度慢、存在错报、漏报，无法测试子弹连发坐标等问题，提出了一种以FPGA为核心的坐标采集和处理系统的设计方法。设计中采用了自顶向下的设计方法，将该系统依据逻辑功能划分为3个模块，并在ISE14．1和Modelsim中进行设计、编译、仿真，最后的仿真结果表明该系统能够很好地采集到子弹的坐标。

Application of FPGA in a new laser screen target system

Combined with applications of coordinate acquisition and processing in a new laser screen target system.Aimed at solving the problems that be lacking of I/O numbers of the controller,slow processing speed,error reports or missing reports, being not able to test the coordinates of continuous shooting bullets in traditional laser screen target system.A designing method for the coordinate acquisition and processing system based on field programmable gate array （FPGA） is put forward. According to the method of top-down, the system is divided into three functional modules. The design,build and simulation of the system are completed in the integration circumstances of ISE 14.1 and Modelsim. The last of the simulation results show that the system can collect the coordinates of bullets very well.
