在片上网络NoC(Network-on-Chip)中,通过光通信取代传统的电信号传输来获得低延时、低功耗成为一种新兴的研究方向—光互连片上网络ONoC(Optical Network-on-Chip).本文提出一种全新的双向传输的波长路由片上网络,这种新的结构对调制好的光信号的波长进行判断来实现在网络节点之间的路由,同时还能够通过器件和传输通道的共享实现数据的双向传输.和传统的电信号传输网络相比,本文提出的双向传输结构减少了50%的硬件开销和70%的芯片面积开销,提高了器件利用率,降低了网络传输延时,极大地提高了网络传输性能,对于光互连片上网络具有重要意义.
In Network-on-Chip (NoC), low latency and low power consumption are the emerging research directions by replacing the traditional transmission of electrical signals by optical communications. Optical Network-on This paper presents a new bidirectional transmission wavelength routing chip on the network, this new structure of the modulated optical signal wavelength to judge in order to achieve the routing between network nodes, but also through the device and transmission Compared with the traditional electrical signal transmission network, the bi-directional transmission structure proposed in this paper reduces the hardware overhead by 50% and the chip area cost by 70%, improves the device utilization and reduces the network transmission Delay, greatly improve the network transmission performance, for optical interconnection on-chip network is of great significance.
