摘　　要：以对激光陀螺的滤波为应用背景,利用FPGA内部RAM、ROM和乘法器IP核为核心,经过可靠的同步时序设计和稳定的逻辑控制设计,在低成本的情况下很好地实现了一种高阶滤波器的设计;并且具有良好的可移植性。使用该滤波器,极大地降低了系统成本和复杂度,可以使设计人员轻松地完成对激光陀螺的高阶滤波,而不需要提高系统硬件成本。For the application of the laser gyro filtering background,internal RAM,ROM and multiplier IP core inside FPGA as the core,after reliable synchronous sequential design and stable logic control design,have been designed a high-order filter with a good portability at a low cost.It not only can reduce the cost and complexity of the system to a great extend through using the filter,but also can make designers to easily achieve higher order filter of the laser gyro,and finally do not need to raise the cost of the system hardware.
