Abstract: A method for a 3D computer graphics shading process compiler, utilized to generate hardware machine code corresponding to a script is disclosed. The method includes the following steps. Operation mapping code indicating an operation of the script, and argument mapping code indicating an argument associated with the operation is provided. The hardware machine code is generated by performing a bitwise OR operation to the operation mapping code and the argument mapping code.

Abstract: A graphics processing unit (GPU) context switching system is provided. The GPU renders digital 3D images based on register values therein. A video random access memory (VRAM) temporarily stores the images before the images are output to a display. A driver controls the GPU. Upon receiving a first request for rendering an image from a first application, the driver generates register values corresponding to the first application according to the first request and writes the register values to the registers of the GPU. Upon receiving a second request for rendering an image from another application, the GPU stores the register values as a first backup in the VRAM.
