Hybrid GPU System Offloading YUV to RGB Conversion

The patent segments the processing workload by separating color space conversion and contrast adjustment operations from the main graphics processing pipeline. The integrated processor handles these specific tasks independently, allowing the discrete graphics processor to focus on rendering operations without the performance penalty of additional color conversion and contrast adjustment computations.

The integrated processor acts as an intermediary that receives video data in YUV format, converts it to RGB color space, and adjusts contrast levels before the data is sent to the discrete graphics processor for rendering. This intermediary approach allows the high-performance discrete GPU to receive pre-processed data without performing the bandwidth-intensive color conversion operations itself.

The patent divides the image processing tasks between two processors with different power characteristics. The integrated processor, which consumes less power, handles the color space conversion and contrast adjustment operations. The discrete graphics processor, which is more power-efficient for rendering, then processes the pre-converted data. This segmentation allows image processing completion while minimizing overall power consumption.

The system uses the integrated processor as a temporary, lower-power processing stage that performs necessary conversions before the data is passed to the main rendering pipeline. This approach treats the integrated processor's conversion operations as a preliminary step that enables the more efficient discrete GPU to complete the rendering task with lower overall power consumption.
