Abstract
A kernel-mode graphics driver (e.g., a D3D driver running under Microsoft Windows) exploits the parallelism available in a dual-core computer system. When an application thread invokes the kernel-mode graphics driver, the driver creates a second (“auxiliary”) thread and binds the application thread to a first one of the processing cores. The auxiliary thread, which generates instructions to the graphics hardware, is bound to a second processing core. The application thread transmits each graphics-driver command to the auxiliary thread, which executes the command. The application thread and auxiliary thread can execute synchronously or asynchronously.
