| Abstract: | This paper analyzes trigonometric functions(mainly Sine function) of the common approximate method,presents an optimization algorithm based on the processor with SIMD function components,and compares the precision and performance to the common series method.It also compares to the GNU math function library in the actual environment.The test results show that the algorithm performance is superior. |
