Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing read/write speed of random access memory do not accurately account for the impact of CPU buffer memories, leading to incomplete evaluation of mobile phone performance.
Innovation Solution
A method and apparatus that calculate a weighted average of test speeds from both random access memory and associated buffer memories to determine the actual read/write speed, considering the impact of buffer memories on the overall performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only random access memory is tested without buffer memory, then test simplicity is maintained, but measurement precision deteriorates because the actual read/write speed cannot be accurately reflected
Solution Approach 1:
The patent segments the memory testing process into distinct phases: buffer memory testing, random access memory testing, and composite testing. By dividing the testing into separate stages with different configurations, the system achieves comprehensive measurement without requiring a completely complex test architecture. The buffer memory and random access memory are tested independently first, then together to derive the actual performance metrics.
2Measurement precision
If buffer memory impact is included in testing, then measurement precision improves, but test complexity increases due to multiple memory components
Solution Approach 1:
The patent employs dynamic testing configurations that can be adjusted between different memory component combinations. The test system dynamically switches between testing buffer memory alone, random access memory alone, and both together, allowing flexible adaptation to different testing scenarios. This dynamic approach enables comprehensive measurement while maintaining operational simplicity through programmable control.
