Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The processing time cannot be shortened when discontinuous data is processed in a logic circuit that needs to be reconfigured, as existing solutions do not efficiently manage the reconfiguration and data transfer processes.
Innovation Solution
An electronic control device with a partially reconfigurable logic circuit that transmits next calculation target data to a storage unit before the reconfiguration of the next calculation unit is completed, allowing the next calculation unit to perform calculations using the stored data once reconfigured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the logic circuit is reconfigured to process discontinuous data, then the calculation capability is improved, but the processing time increases due to reconfiguration delays
Solution Approach 1:
The patent applies preliminary action by transmitting calculation target data to the storage unit before the reconfiguration of the calculation unit is completed. This allows the data to be ready in the storage unit when the calculation unit finishes reconfiguring, eliminating waiting time and reducing overall processing time while maintaining the ability to handle discontinuous data streams.
2Reliability
If the calculation unit waits for reconfiguration completion before processing data, then the calculation accuracy is ensured, but the processing efficiency decreases
Solution Approach 1:
The system performs preliminary data transmission to the storage unit before reconfiguration completes, ensuring data is ready when needed. This maintains calculation accuracy by ensuring data availability while improving efficiency by eliminating idle waiting time during reconfiguration.
Solution Approach 2:
The patent maintains continuity of useful action by overlapping the data transmission process with the reconfiguration process. Both operations proceed simultaneously, ensuring that the calculation unit can immediately begin processing once reconfiguration is complete without interruption, thereby maintaining both accuracy and efficiency.

AI summary
An electronic control device includes: a partially reconfigurable logic circuit in which a calculation unit which is reconfigured and executes calculation and a storage unit which stores calculation target date to be calculated by the calculation unit is configured; and a processing control unit which transmits circuit data for reconfiguring the calculation unit and the calculation target date to the logic circuit. When the processing control unit obtains next calculation target data which is the calculation target date relating to a next calculation unit which is the calculation unit after completion of reconfiguration, transmission of the next calculation target date to the storage unit is started regardless of whether the reconfiguration of the next calculation unit is completed, and upon completion of the reconfiguration, the next calculation unit performs calculation using the next calculation target date.
