In allusion to the disadvantage of processing Fill-in Signal Unit(FISU) using CPU,on the basis of analyzing the process of initial aligning and HSU processing in No.7 signaling system,a new design scheme adopting Field-Programmable Gate Array(FPGA) to achieve FISU filter is put forward.The principle figures,communication mechanism between FPGA and CPU,and signal processing flow charts are carded out.ISE and ModelSim software are used to achieve simulation.Simulation result proves that the scheme is correct,feasible and effective.
