Strongly Typed API Handle for GPU State Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing graphics pipeline state management systems face performance bottlenecks due to the need for frequent validation and setting of shader constants, leading to increased time spent on redundant operations and reduced rendering capabilities.
Innovation Solution
Implementing a 'strongly typed API handle' system that performs validation at handle retrieval time, allowing for pre-validation during application load time and eliminating the need for repeated validation during frame rendering, thereby enabling faster value setting and reducing redundant operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If validation is performed during each value-setting operation in the graphics pipeline, then data accuracy and type correctness are ensured, but rendering performance deteriorates due to redundant validation operations
Solution Approach 1:
The patent performs validation during handle retrieval at application load time rather than during each subsequent value-setting operation. This preliminary validation ensures data accuracy once, and then the validated handle can be reused multiple times without repeated validation, thereby maintaining reliability while improving rendering performance by eliminating redundant validation operations during frame rendering
2Manufacturing precision
If frequent validation and setting of shader constants is performed, then state management accuracy is maintained, but time consumption increases leading to bottlenecks in the graphics pipeline
Solution Approach 1:
The patent performs validation and state management operations during handle retrieval at application load time rather than during each value-setting operation. This preliminary action ensures state management accuracy is established once, and then the handle can be reused without repeated validation, thereby maintaining accuracy while reducing time consumption and eliminating bottlenecks during frame rendering
3Ease of operation
If handle-based techniques are used for state management, then flexibility and ease of operation are improved, but processing speed deteriorates due to internal lookups and type checking during runtime
Solution Approach 1:
The patent performs internal lookups and type checking during handle retrieval at application load time rather than during runtime value-setting operations. This preliminary action maintains the flexibility and ease of operation of handle-based techniques while improving processing speed by eliminating repeated lookups and type checking during frame rendering, allowing the system to use fast paths for subsequent operations

AI summary
In a state management system of an effects system implemented in a Graphics Processing Unit (GPU), techniques and technologies are provided for setting a value to particular variables at application run-time without validating the variables. For example, a compiled effects file comprising a number of variables can be loaded at application load time, and a generic, variable interface pointer for a particular variable of the effects file can be retrieved. A specialized variable interface pointer can then be generated which is associated with the particular variable by specifying a desired type of access that will be performed on the particular variable. At application run-time, the specialized variable interface can be used to set a value to each of the particular variables without validating the particular variables at application run-time.
