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

A method for processing data, a memory management unit and a memory control device are disclosed. In an embodiment, the method includes receiving, by a memory control device, a first data packet carrying a virtual address and a page table base address that are sent by a memory management unit, executing, by the memory control device, a page table walk operation according to the virtual address and the page table base address, to obtain a physical address corresponding to the virtual address and sending, by the memory control device, the physical address corresponding to the virtual address to the memory management unit.

Data processing method, memory management unit, and memory control device

A network-on-chip flit transmission method and a network-on-chip flit transmission apparatus. The method includes: receiving a current flit including an operation ID Op ID, an operation type Op Type, and a payload; when determining that acceleration processing needs to be performed on the current flit, determining, according to the Op Type, whether the payload of the current flit affects an execution result of a destination node of the current flit, where the execution result is a result obtained by executing, by the destination node, a task corresponding to the Op ID; and forwarding the current flit to a next node if a determining result is yes; and discarding the current flit if a determining result is no. Therefore, not only a quantity of flits that need to be transmitted on a network-on-chip can be greatly reduced, but also a calculation amount of the destination node can be reduced.

Network-on-chip flit transmission method and apparatus

A method, an apparatus, and a system for configuring a flow table in an OpenFlow network, which can enhance a service switchover adaptation capability of a network system, and improve the working efficiency. The method includes determining, by a control device, a type of a service needing to be forwarded by a switch device; determining, according to the type of the service needing to be forwarded by the switch device and a prestored correspondence between a service type and flow table matching capability information, flow table matching capability information corresponding to the service type, and sending a flow table configuration message to the switch device, where the flow table configuration message carries the flow table matching capability information corresponding to the service type, so that the switch device configures, according to the flow table matching capability information, a flow table required for the service type.
