ABSTRACT:
The system includes an arbiter, a combined engine, a frame buffer, and a display processing unit. The arbiter provides three input channels: a first channel for graphics, a second channel for video and a third channel for processor. The arbiter performs prioritization and arbitration between the video and graphics and processor requests sent to the system. The arbiter has three output ports coupled to the combined engine. The combined engine is a hardware engine capable of processing either video data or graphics data. The output of the combined engine is provided to the frame buffer for the storage of pixel data. The output of the frame buffer is coupled to a display processing unit that renders the pixel data for display.
