Abstract: Provided is a mask operation method for an explicit independent mask register in a GPU. The method comprises: each GPU hardware thread being able to access respective eight 128-bit-wide independent mask registers, which are recorded as $m0-$m7. With regard to mask operation instructions of the explicit independent mask register in the GPU, each hardware thread in the GPU is able to access respective eight 128-bit-wide independent mask registers, and four groups of mask operation instructions are available for a user, and respectively realize a reduction operation, an extension operation and a logic operation on the mask register, and data movement between the mask register and a general vector register.

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.
