Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If memory-based compression techniques are used, then compression functionality is provided, but power consumption increases and compression length control becomes inflexible
Solution Approach 1:
The patent extracts the compression functionality from memory-based systems and relocates it to dedicated compression units within the fabric infrastructure. This allows compression operations to be performed closer to the data flow path, reducing the need for extensive memory allocations and control value storage, thereby lowering power consumption while maintaining flexible compression length control.
Solution Approach 2:
The patent introduces fabric-based compression units as intermediary components between data sources and destinations. These units act as mediators that perform compression operations inline with the data flow, eliminating the need for traditional memory-based compression approaches that require large allocations for control values and intermediate storage.
2Productivity
If fixed function computational units are used, then specific operations are performed efficiently, but adaptability to different compression lengths is limited
Solution Approach 1:
The patent implements dynamic compression units within the fabric that can adapt their operation mode and compression length based on real-time requirements. Unlike fixed function units, these fabric-based compression elements can be configured to handle variable compression lengths while maintaining efficient processing through hardware-accelerated operations.
Solution Approach 2:
The fabric-based compression units are designed as multi-functional elements that can perform various compression operations with different compression ratios and lengths. This universal approach replaces the need for multiple specialized fixed function units, providing both efficiency and adaptability within a single fabric infrastructure.
3Device complexity
If limited memory allocation is used for control values, then device complexity is reduced, but compression control flexibility deteriorates
Solution Approach 1:
The patent replaces the mechanical memory-based control system with a fabric-based control mechanism. Instead of storing control values in allocated memory, the system uses fabric infrastructure to carry control information, eliminating the need for extensive memory allocations while maintaining full compression control flexibility.
Solution Approach 2:
The patent moves the control mechanism from a memory dimension (storage-based control) to a fabric dimension (transmission-based control). By utilizing the fabric infrastructure for control value transmission rather than memory storage, the system achieves both reduced complexity and maintained flexibility.
