A network on chip (NoC), a communication control method, and a controller are provided. The NoC includes multiple routers and multiple network interfaces NIs, each router in the multiple routers is connected to one local node device using one NI, and each router includes one output port connected to an NI, one input port connected to the NI, multiple output ports connected to other routers, and multiple input ports connected to other routers; there is an input bypass channel between the output port that is connected to an NI and of each router and each input port that is connected to another router and of the router. There is an output bypass channel between the input port that is connected to an NI and of each router and each output port that is connected to another router and of the router.

Network on chip, communication control method, and controller

An optical network-on-chip and a method and an apparatus for dynamically adjusting optical link bandwidth is presented, wherein each fixedly interconnected optical transceiver in a cluster in the optical network-on-chip is configured to establish a link between the cluster and one cluster in other n-x clusters to exchange an optical signal; and a main controller is configured to allocate x adaptively interconnected transceivers to k fixed links with the heaviest communication traffic according to a set rule and communication traffic of fixed links established by n-x fixedly interconnected optical transceivers in the cluster; and for an adaptively interconnected optical transceiver in the x adaptively interconnected optical transceivers, control the adaptively interconnected optical transceiver to establish a link, except the fixed link, between two clusters connected by the fixed link.
