By Taylor polynomial method to achieve computing sine function,the value of the input signal normalizes to the vicinity of zero as the input values of Taylor polynomial.The 32 floating-point addition and multiplication modules are developed by VHDL on the FPGA experimental platform in accordance with Taylor polynomial to approximate the value of sine function mapping on the VHDL programme.All data are based on IEEE-754 32-bit single-precision standards participate in function computing.Therefore,they can be compatible with most of the processors,and Complete circuits containing sine computing such as chaotic circuit,filtering technology,voice and image processing easily on the FPGA experimental platform.
