Since MCU is more and more widely used in mobile devices,its stronger data handling capacity is required,but the resources of MCU are limited. Therefore,how to make it resolve the complicated functions becomes very meaningful,and it also becomes one of the problems puzzling the experts. A kind of algorithm for operating the complicated trigonometric functions is introduced,which uses interpolation method and look-up table method in assemble language. The computational accuracy of this algorithm for the trigonometric function can reach 0.0001,and its memory space reduces 97%. The relevant content is elabo-rated fully in this paper. The method has high computational accuracy and wide application,and is easy to master.
