Transcendental function processing method, transcendental function unit and graphics processor

The invention provides a transcendental function processing method, a transcendental function unit and a graphics processor. The method comprises the following steps: acquiring an input floating-point number and a transcendental function; determining a target function according to the floating-point number and the transcendental function; determining an interpolation function according to the interpolation point and the target function; determining a tail value according to the interpolation function; and obtaining a transcendental function result based on the mantissa value. According to the method provided by the invention, the mantissa value is obtained according to the floating-point number, the transcendental function and the interpolation function, and the result of the transcendental function is obtained based on the mantissa value, so that the precision requirement meeting actual application is obtained under the condition of relatively low overhead. 本申请提供一种超越函数的处理方法、超越函数单元、图形处理器，该方法获取输入的浮点数和超越函数；根据浮点
