GRAPHICS SYSTEM AND METHOD FOR MINIMIZING THE IDLE TIME OF A HOST PROCESSOR IN THE GRAPHICS SYSTEM

A graphics system minimizes the idle time of a host processor while sending a large amount of graphics instructions in a graphics system. The graphics system includes a host processor, a system memory, a graphics memory and a graphics accelerating device (GAD) that interconnects the host processor and the graphics memory. The host processor divides the graphics instructions into graphics commands and graphics data and temporarily stores the graphics data in the system memory. The GAD receives the graphics commands coming from the host processor and receives the graphics data coming from the system memory, respectively, and sends the processed outcome to the graphics memory. Due to the graphics data being temporarily stored in the system memory, the host processor will not be idle even though many consecutive 3D graphics instructions are sent from the host processor to the GAD.
