摘　　要：针对现有声靶控制器在应用中的局限性,设计了一种基于FPGA和PCI-E总线的多功能声靶控制器;控制器以FPGA为核心,通过对控制器进行功能划分,在FPGA实现了A/D、D/A的控制器,数据FIFO,前置电路逻辑控制器,和系统时序控制器;最后以第三代计算机总线PCI-E为数据接口,完成控制器与计算机的数据交换;经过时序仿真和在实际中的应用,控制器达到了设计的功能和指标,验证了设计思想的正确性。Aim at the limitation in application of acoustics target controller, a multi--functions controller of acoustics target has been designed based on FPGA and PCI--E bus. As the center of the controller, the FPGA has been partitioned into A/D unit, D/A unit, data FIFOs, logic unit, and system timing unit; then, the controller completes the data transmission using the third generation computer bus PCI-E. The timing simulation and application in reality indicate that the controller reachs the functions and performance, and confirm the idea of the design.
