摘要
结合数据采集在弹丸激光测速靶测量系统中的应用,介绍了一种基于FPGA(现成可编程门阵列)为核心的多通道数据采集系统的设计方案。设计中采用了自顶向下的设计方法,将FPGA依据逻辑功能划分为几个模块,详细论述了各模块的设计方法。各逻辑模块设计使用VHDL语言,并在QuartusII中完成软件设计和仿真。
Combined with applications of data acquisitions in laser measuring system, a method for designing the data acquisitions system based on FPGA is described. According to the method of top-down, FPGA is divided into several functional modules. The designing method and controlling flow of each module are discussed in detail. The VHDL language is adopted in each logic module. Software design and system simulation are completed in the integration circumstance of QuartusⅡ.
