Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If design data is stored in the database for circuit updating, then circuit update capability is improved, but storage capacity is consumed
Solution Approach 1:
The patent uses analysis to generate design data from the reconfigurable unit's current circuit configuration, creating a representation of the circuit state without storing the actual design data. This copying approach allows the system to track and update circuits while consuming minimal storage space, as only essential configuration information is retained rather than complete design datasets.
Solution Approach 2:
The patent extracts only the necessary information from the reconfigurable unit's circuit configuration to generate design data for updating. By taking out only the essential logic block settings and inter-logic-block connection information needed for circuit updates, the system avoids storing redundant data while maintaining full circuit update capability.
2Reliability
If encryption is applied to design data, then security is improved, but processing complexity increases
Solution Approach 1:
The patent applies encryption to design data before storing or transmitting it to the reconfigurable unit. By performing the encryption action in advance, the system ensures security is established before the data enters the update process, reducing the need for continuous security checks and simplifying the overall processing flow while maintaining high security standards.
