Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical communication channels are shared by multiple links to increase flexibility, then adaptability is improved, but latency increases and contention occurs
Solution Approach 1:
The communication channels are segmented into dedicated channels for timing-critical signals and shared channels for non-timing-critical traffic. This segmentation allows timing-critical signals to have guaranteed low-latency paths while non-critical traffic utilizes shared resources for improved flexibility and bandwidth efficiency.
Solution Approach 2:
Different quality of service is provided to different types of traffic locally at each communication channel. Timing-critical signals receive priority handling and dedicated resources, while non-timing-critical traffic receives shared access with lower priority, optimizing overall system performance for mixed traffic types.
2Speed
If dedicated physical communication channels are assigned to specific circuit pairs to reduce latency, then speed is improved, but device complexity increases and bandwidth is limited
Solution Approach 1:
The switching architecture is segmented into static switching components for timing-critical paths and dynamic switching components for flexible routing. This segmentation reduces overall complexity by allowing each component to be optimized independently rather than requiring a fully dynamic complex switch for all traffic.
Solution Approach 2:
The system employs dynamic switching circuitry that can reconfigure connections based on traffic demands while maintaining static dedicated paths for timing-critical signals. This dynamic adaptability allows the system to optimize bandwidth utilization without sacrificing the low latency required for time-sensitive communications.
3Productivity
If more physical communication channels are added to increase bandwidth, then productivity is improved, but device complexity and control resource requirements increase
Solution Approach 1:
The dynamic switching circuitry is designed to handle multiple functions including routing, arbitration, and resource allocation across all communication channels. This multi-functionality allows a single control mechanism to manage increased bandwidth requirements without proportionally increasing overall system complexity.
Solution Approach 2:
Communication channels are segmented into dedicated and shared categories, allowing bandwidth to be increased through efficient sharing of physical channels rather than adding more physical channels. This segmentation enables high bandwidth utilization with reduced complexity compared to a fully dedicated channel architecture.
