Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If distributed processing is used among multiple graphics processors, then processing capability is improved, but synchronization between processors deteriorates leading to tearing and visual defects
Solution Approach 1:
The patent introduces a data structure acting as an intermediary between multiple graphics processors to coordinate their operations. This data structure serves as a shared communication medium that enables processors to signal and synchronize their read/write operations, preventing tearing and visual defects while maintaining distributed processing capabilities.
2Speed
If a second graphics processor retrieves data from memory before the first processor completes writing, then processing speed is improved, but data integrity deteriorates causing visual defects
Solution Approach 1:
The patent implements a synchronization mechanism where the second graphics processor checks the data structure before retrieving data to ensure the first processor has completed writing. This preliminary verification action prevents data integrity issues while allowing fast parallel processing when synchronization conditions are met.
