Offline Shader Compilation for Mobile GPU Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shader compilation methods on mobile devices result in long application launch times and unpredictable pauses due to runtime compilation and state-dependent recompilation, which is unsuitable for mainstream consumer computing platforms with varied graphics architectures.
Innovation Solution
A cloud-based application distribution system that identifies a compiler matching the mobile device's configuration, compiles shader source code with state information into a pre-compiled auxiliary package, and provides it along with the primary application package, allowing for efficient graphical processing and rendering without the need for on-demand compilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shader compilation is performed at runtime on mobile devices, then the application can adapt to different GPU architectures and driver versions, but application launch times become long and unpredictable due to compilation delays
Solution Approach 1:
The patent performs shader compilation in advance during the application packaging phase rather than at runtime. The build system compiles shaders for multiple target configurations ahead of time, stores the compiled binaries in the application package, and distributes them to devices. This preliminary action eliminates compilation delays during application launch while maintaining adaptability across different GPU architectures through pre-compiled binaries tailored to specific hardware configurations.
2Adaptability or versatility
If shader compilation is performed on-demand during application execution, then the system can handle state-dependent shader variations, but unpredictable pauses occur during execution due to recompilation
Solution Approach 1:
The patent pre-compiles shaders for multiple state configurations during the build process. The build system generates shaders for various state combinations in advance, stores them in the application package, and the runtime system selects the appropriate pre-compiled shader based on current device state. This eliminates on-demand recompilation and associated execution pauses while maintaining the ability to handle state-dependent variations.
Solution Approach 2:
The patent implements a dynamic shader selection mechanism that adapts to runtime device state without recompilation. The system determines the current device state (GPU architecture, driver version, graphics API state) and dynamically selects the most appropriate pre-compiled shader binary from the package. This dynamic selection approach maintains adaptability to state variations while avoiding the performance penalty of recompilation during execution.
3Adaptability or versatility
If multiple shader executables are created for different hardware configurations, then compatibility across devices is improved, but the complexity of shader management increases
Solution Approach 1:
The patent creates a universal application package structure that contains pre-compiled shader binaries for multiple target configurations. The package includes shaders compiled for various GPU architectures, driver versions, and graphics API states. This universal package can be distributed once and deployed to diverse devices, with the runtime system automatically selecting the appropriate shader based on device characteristics. This approach maintains broad hardware compatibility while simplifying distribution and management compared to maintaining separate applications for each configuration.
Data Source
AI summary
Systems and techniques are provided that allow for installation of an application on a mobile device using a shader executable suitable for execution by the mobile device. When a request to install an application is received by an application distribution platform, a shader configured for the device is generated by the platform and provided with the application package for installation on the device. Thus, launch-time compilation and just-in-time re-compilation may be avoided.
