【 摘 要 】

References(9)In optical Network-on-Chip (NoC), packet switching remains popular owing to its scalability and reliability. Considering no mature optical buffering technology, deflection routing is preferable to resolve the output port contention. Reduction of deflection probability is essential to bufferless deflection optical NoC. This letter proposes a new 5*5 router architecture, and especially a deflection-supported switching fabric. Moreover, an ejection unit and an injection unit are designed to reduce the deflection. Additionally, priority-based routing computation and port allocation algorithms are designed based on the new switching fabric. The simulation results show that our proposal can improve performance at acceptable insertion loss.
