Abstract
Dual processor accelerated graphics rendering is a method which allows for optimizing graphics performance using two processors and 3D hardware accelerators. This method allows for real time embedded systems to have multiple partitions to render to multiple windows with non-blocking graphics calls. One processor queues up graphics calls within a discrete time because they do not interface with the graphics accelerator hardware. The second processor supports the hardware accelerator with drivers operating in a single partition. This design abstracts the graphics calls from the native interface of the graphics hardware accelerator.
