一种新的处理器间光互连网络

随着计算机系统对互连网络性能需求的提高,传统的电互连技术出现了许多无法克服的问题,光互连技术应运而生。本文设计了一种新的基于高速光开关的处理器间光互连结构——PIBOS,并在此基础上提出了单级PIBOS和多级PIBOS中的链路仲裁和路由算法。模拟结果表明,采用PIBOS互连结构,减少了数据传输过程中的光电转换操作,提高了网络的吞吐率,降低了系统延时,并很好地实现了互连系统的扩展。

A Novel Inter-Processor Optical Interconnection Network

With the improvement of the demands on high-performance interconnection networks, the traditional electric interconnection cannot meet the needs of high-speed data transmission. Therefore, the technology of optical interconnection is brought forward. A new inter-processor optical interconnection fabric named PIBOS is put forward, which includes the single-level PIBOS and the multilevel PIBOS. The simulation results show that the single-level PIBOS interconnection network can reduce packet latency,and improv...
