This paper introduces a design of the sine function calculator on FPGA. It can calculate the sine value from 0 to 90 degree. The precision of system input is 0. 2 degree,and the precision of output is 0. 001. The sine function calculator is described in VHDL,and synthesized,simulated with Max＋plus Ⅱ foundation. The experimental results show that the performance has conform to the proposed algorithm. The generality of this design is good, According to modifying the specific parameters, it can be used into the design of divers digital circuit systems.
