Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple channels are used to increase read speed, then data reading efficiency is improved, but the complexity of controlling data output order increases
Solution Approach 1:
The control circuit is segmented into three functional modules: multiplexing circuit for channel selection, sorting circuit for order management, and arbitration circuit for conflict resolution. This segmentation allows each module to handle specific tasks independently, improving overall control efficiency while maintaining manageable complexity.
Solution Approach 2:
The sorting circuit acts as an intermediary between the multiplexing circuit and the decoder, managing the data output order from multiple channels. It receives channel data selection signals, sorts them according to predetermined digital numbers, and outputs sorted signals to the arbitration circuit, thereby mediating the complex multi-channel control.
2Measurement precision
If the output order is dynamically adjustable, then data reading accuracy is improved, but the response time for correction increases
Solution Approach 1:
The sorting circuit is pre-configured with predetermined digital numbers that define the correct output order for multiple channels. This preliminary setup allows the arbitration circuit to quickly determine the correct channel selection without complex real-time calculations, enabling fast correction when output order errors occur.
Solution Approach 2:
The arbitration circuit continuously monitors the data output order and compares it with the predetermined correct order. When an error is detected, the feedback mechanism triggers immediate correction by adjusting the channel selection signal through the sorting circuit, ensuring both accuracy and rapid response time.
3Reliability
If arbitration circuit instantly corrects output order, then data reading reliability is improved, but the device complexity increases
Solution Approach 1:
The arbitration circuit implements dynamic correction capability by continuously monitoring channel output orders and instantly adjusting the selection signal when errors are detected. This dynamic operation ensures high data reading reliability while the modular design keeps the circuit complexity manageable through clear functional separation.
