A method for high-speed signal acquisition based on FPGA is proposed

and the design of sampling

storage and communication module is described in detail.The function of the module is designed based on VHSIC hardware description language（VHDL）

and the finite state machine is used

which not only enhances the flexibility of design

but also reduces the costs.An experimental result of the signal acquisition is given and it is proved that the high-speed signal acquisition platform can work steadily and reliably.
