Equivalent random sampling technique's FPGA simulation

Uses cyclone series FPGA of Altera corporation: EP1C12Q240C8,and hardware description language VHDL,in the environment of the software Quartus II 6.0 to construct a simulation model which based on a sorting algorithm to simulate a equivalent random sampling system.And use special method if can not sample completely.After the simulation,high speed data acquisition system designed runs steady,achieving real-time sampling rate of 50 M SPS,the equivalent sampling rate of 1.6 G SPS,which basically arrive at the expected aims.
