This paper studies the realization methods of float arithmetic and trigonometric functions based on fixed-point DSP TMS320F2407,which use the mantissa and factorial method to calculate addition,subtraction,multiplication and division,and apply the power series spread and arithmetic operation to realize float trigonometric functions.The paper compiles the arithmetic on TMS320F2407.The experimental data of sine are given,which show the arithmetic with high precision and rapid speed,can be used on other single-chip microprocessor.
