Engineering Contradiction Analysis
1Ease of operation
If a distributed approach with multiple processors is used to generate CTC signals, then flexibility and ease of operation are improved, but device complexity increases
Solution Approach 1:
The control system is segmented into multiple independent processors (first processor, second processor, third processor) within the microcontroller, each handling specific CTC signal generation tasks. This segmentation allows individual processors to be optimized for specific functions while maintaining overall system flexibility through firmware updates without requiring hardware changes.
2Productivity
If reaction data is stored in different data formats, then productivity is improved through efficient storage and computation, but device complexity increases
Solution Approach 1:
The system employs multiple data formats for storing reaction data, allowing the first processor to efficiently store and retrieve data in optimized formats for different computational needs. This enables faster processing and reduced memory access time while the microcontroller manages the complexity of format conversion and selection transparently.
3Ease of operation
If CTC signals are divided into groups based on memory operations, then ease of operation is improved, but device complexity increases
Solution Approach 1:
CTC signals are segmented into distinct groups corresponding to different memory operations (read, write, erase). Each processor group manages specific signal groups, making the system easier to operate and debug while the microcontroller coordinates between groups to maintain overall system coherence.
Solution Approach 2:
The microcontroller serves as a universal coordinating entity that manages multiple processor groups and their respective CTC signal groups. This multi-functional component handles inter-group coordination, ensuring that the organized structure does not compromise system-wide signal synchronization.
