Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data-intensive operations are handled by the host device, then processing capability is improved, but data transfer volume increases and latency increases
Solution Approach 1:
The patent extracts data-intensive operations from the host device and relocates them to the storage device. The storage device includes a reconfigurable logic array that can be configured to perform filtering, sorting, grouping, and other data-intensive operations directly on stored data, eliminating the need to transfer large volumes of data to the host device for processing.
Solution Approach 2:
The patent introduces a reconfigurable logic array as an intermediary component between the storage memory and the host device. This logic array acts as a mediator that performs data processing operations within the storage device, reducing the data transfer burden on the host device while maintaining processing capability.
2Adaptability or versatility
If data-intensive operations are handled by the host device, then processing flexibility is improved, but resource utilization of host device increases excessively
Solution Approach 1:
The patent implements a reconfigurable logic array that can dynamically change its configuration based on the specific data-intensive operation required. The logic array can be reconfigured to perform different operations such as filtering, sorting, grouping, and aggregation, providing processing flexibility while keeping the operational logic within the storage device to reduce host device resource utilization.
3Loss of substance
If storage device performs data-intensive operations, then data transfer volume is reduced, but device complexity increases
Solution Approach 1:
The patent implements a universal reconfigurable logic array that can perform multiple data-intensive operations including filtering, sorting, grouping, and aggregation. This single multi-functional component reduces the need for separate dedicated hardware for each operation, thereby reducing overall device complexity while enabling the storage device to perform various data-intensive operations and reduce data transfer volume.
