Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple compute cores are used to increase computational capacity, then productivity is improved, but device complexity and synchronization difficulty worsen
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission for inter-core communication. Optical signals use light instead of electrical currents, enabling faster transmission speeds and better signal integrity across multiple compute cores, thereby improving synchronization capability while maintaining computational capacity
Solution Approach 2:
The optical broadcast network serves multiple functions simultaneously: it transmits computational data between compute cores, provides synchronization signals, and enables coordinate computation across all cores. This multi-functionality reduces the need for separate dedicated synchronization circuits, simplifying the overall system complexity while supporting multiple compute cores
2Speed
If optical signals are used for data transmission, then speed is improved, but synchronization reliability worsens
Solution Approach 1:
The system employs periodic synchronization signals transmitted through the optical broadcast network at regular intervals. These periodic signals ensure that all compute cores maintain synchronized timing, compensating for potential drift and ensuring reliable coordination despite the high-speed optical transmission
Solution Approach 2:
The patent implements feedback mechanisms where compute cores monitor the received optical signals and adjust their operation accordingly. This feedback ensures that synchronization is maintained by detecting and correcting timing deviations, thereby improving synchronization reliability while maintaining high transmission speeds
