Engineering Contradiction Analysis
1Productivity
If byte-based alignment is used in memory devices, then data access simplicity is maintained, but processing performance is limited and power consumption increases
Solution Approach 1:
The patent implements dynamic alignment conversion that transforms data between byte-based and non-byte-based alignments based on processing requirements. The system dynamically adjusts alignment modes during operation, allowing optimal performance for different computational tasks while managing power consumption adaptively.
Solution Approach 2:
The invention changes the alignment parameter from fixed byte-based to flexible non-byte-based alignment. By modifying the data organization parameter within the memory device, the system achieves improved processing performance for specific operations without requiring external processing resources.
2Productivity
If byte-based alignment is used in memory devices, then compatibility with standard interfaces is maintained, but processing efficiency and parallelism are reduced
Solution Approach 1:
The patent segments the memory device into multiple banks, each capable of independent alignment operations. This segmentation allows parallel processing of multiple data sets with different alignment requirements, improving overall processing efficiency while distributing the alignment conversion complexity across multiple independent units.
Solution Approach 2:
The memory device is designed with universal alignment conversion capability that can handle both byte-based and non-byte-based alignments within the same device. This multi-functionality allows the device to maintain compatibility with standard interfaces while simultaneously supporting optimized non-byte-based operations.
3Adaptability or versatility
If data movement between memory arrays is increased, then processing-in-memory capabilities are enhanced, but power consumption and processing time increase
Solution Approach 1:
The patent merges multiple memory banks into a unified processing-in-memory system where data can be processed in place within the memory array. By combining storage and processing functions within the same memory structure, the system enhances adaptability for complex operations while minimizing data movement time through local processing capabilities.
