The high speed symmetrical random number generator based on FPGA

It is described a high speed symmetrical random number generator that allows us to be used in the information theory,control theory,dependable theory and artificial theory etc.On account of actual demand,a high speed symmetrical random number generator based on FPGA has been designed by virtue of VHDL.So,a fast and highly efficient generator is integrated on one chip of FPGA.Finally,simulations are performed with Quartus Ⅱand desired results are obtained.
