Smart Compositor Module Allocates Layers Across DPU Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display processing techniques inefficiently utilize display processing unit (DPU) resources, as GPUs are used for composition while some DPU resources remain unused, leading to suboptimal performance and increased power consumption.
Innovation Solution
A smart compositor module allocates and composes layers across multiple DPU portions based on their composition capabilities, utilizing a second DPU as a composition device to enhance the composition capacity and reduce reliance on the GPU for layer composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If GPU is used for layer composition, then composition capability is provided, but DPU resources remain unused and power consumption increases
Solution Approach 1:
The DPU is designed to perform multiple functions including both display processing and layer composition. By enabling the DPU to handle composition tasks that were traditionally performed by the GPU, the system achieves better resource utilization and reduces power consumption while maintaining composition capability.
Solution Approach 2:
The DPU serves itself by performing layer composition internally rather than relying on external GPU resources. This self-service approach allows the DPU to utilize its own unused resources for composition tasks, improving overall system efficiency and reducing the need for additional high-power components.
2Productivity
If GPU is used for layer composition, then composition tasks are performed, but resource utilization is inefficient
Solution Approach 1:
The patent merges the composition function with the DPU's existing display processing capabilities. By combining layer composition with display output processing in a single unit, the system eliminates the need for separate GPU involvement in composition, thereby improving resource utilization and reducing system complexity.
Solution Approach 2:
The display processing system is segmented into distinct functional portions within the DPU, where different portions can be independently allocated for composition tasks. This segmentation allows flexible resource allocation and efficient utilization of DPU capabilities without requiring complex inter-component coordination.
3Productivity
If multiple layers are composed by single DPU, then composition capacity is limited, but resource utilization improves
Solution Approach 1:
The DPU is divided into multiple functional portions or processing units, each capable of handling composition tasks. This segmentation enables parallel processing of multiple layers simultaneously, increasing the overall composition capacity while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent introduces an additional processing dimension by utilizing unused DPU resources and portions that were previously idle. By activating these dormant resources for composition tasks, the system effectively increases composition capacity without adding external components, thereby scaling performance through internal resource optimization.
