本文在已设计完成的用于计算机点到虚拟并行互连的光互连链路基础上 ,用现场可编程门阵列(FPGA)器件实现了数据的寻址和转发 ,设计完成了具有硬件路由功能的光互连环网的网络接口卡。该网络接口卡的旁路数据转发延迟为 2 1 0 ns,目的结点的数据接收处理延迟为 35 0 ns
Based on the designed optical interconnection links for point-to-point virtual parallel interconnection, this paper realizes the data addressing and forwarding with field programmable gate array (FPGA) devices. The design has completed the hardware routing function Optical Interconnect Ring Network Interface Card. The network interface card bypass data forwarding delay of 210 ns, the destination node data reception processing delay of 35 0 ns
