  • Methods and apparatuses for computing trigonometric functions with high precision
    Patent number: 10353672
    Abstract: A method for computing trigonometric functions, performed by an ALU (Arithmetic Logic Unit) in coordination with an SFU (Special Function Unit), is introduced to contain at least the following steps. The ALU computes a remainder r and a reduction value x* corresponding to an input parameter x. The SFU computes an intermediate function f(x*) corresponding to the reduction value x*. The ALU computes a multiplication of the reduction value x* by the intermediate function f(x*) as the computation result of a trigonometric function.
