Solution Overview
Problem
Existing electronics devices face challenges in efficiently supporting both 2-D and 3-D graphics with minimal hardware to reduce cost and power consumption, as they require separate GPUs for each type, leading to inefficiencies in resource utilization.
Innovation Solution
A GPU is designed to perform both 2-D and 3-D graphics processing by mapping stages of the 2-D graphics pipeline to stages of the 3-D graphics pipeline, allowing shared use of processing units and supporting various blending modes, enabling efficient processing for both 2-D and 3-D graphics operations.

1Productivity
If separate GPUs are used for 2-D and 3-D graphics processing, then processing performance for each type is optimized, but hardware cost and power consumption increase
Solution Approach 1:
The patent implements a universal GPU architecture that can perform both 2-D and 3-D graphics processing through a unified pipeline. The GPU includes processing units configured to execute both 2-D graphics pipeline stages (vertex processing, rasterization, fragment processing) and 3-D graphics pipeline stages, eliminating the need for separate dedicated GPUs for each graphics type while maintaining optimized performance for both applications.

3Device complexity
If a single GPU supports both 2-D and 3-D graphics, then hardware requirements are reduced, but processing efficiency may deteriorate
Solution Approach 1:
The patent segments the graphics processing pipeline into distinct 2-D specific stages (clipping, masking, scissoring, coverage determination) and 3-D specific stages (depth testing, fragment shader processing), while sharing common processing units. This segmentation allows the GPU to efficiently handle both 2-D and 3-D graphics by routing operations to appropriate specialized sub-stages within the unified architecture, maintaining high processing efficiency despite hardware reduction.
4Device complexity
If processing units are shared between 2-D and 3-D graphics pipelines, then hardware cost is reduced, but resource utilization efficiency may worsen
Solution Approach 1:
The patent implements dynamic resource allocation where processing units can be dynamically configured and allocated to different pipeline stages based on the current graphics processing task. The GPU controller can dynamically route 2-D graphics operations to appropriate processing units and switch between 2-D and 3-D processing modes, optimizing resource utilization efficiency for each specific operation while maintaining the benefit of shared hardware architecture.

AI summary
Techniques for supporting both 2-D and 3-D graphics are described. A graphics processing unit (GPU) may perform 3-D graphics processing in accordance with a 3-D graphics pipeline to render 3-D images and may also perform 2-D graphics processing in accordance with a 2-D graphics pipeline to render 2-D images. Each stage of the 2-D graphics pipeline may be mapped to at least one stage of the 3-D graphics pipeline. For example, a clipping, masking and scissoring stage in 2-D graphics may be mapped to a depth test stage in 3-D graphics. Coverage values for pixels within paths in 2-D graphics may be determined using rasterization and depth test stages in 3-D graphics. A paint generation stage and an image interpolation stage in 2-D graphics may be mapped to a fragment shader stage in 3-D graphics. A blending stage in 2-D graphics may be mapped to a blending stage in 3-D graphics.
