A computer device and a method for reading or writing data by a computer device are provided. In the computer device, a central processing unit (CPU) is connected to a cloud controller using a double data rate (DDR) interface. Because the DDR interface has a high data transmission rate, interruption of CPU can be avoided. In addition, the CPU converts a read or write operation request into a control command and writes the control command into a transmission queue in the cloud controller. Because the cloud controller performs a read operation or a write operation on a network device according to operation information in the control command, after writing the control command into the transmission queue, the CPU does not need to wait for an operation performed by the cloud controller and can continue to perform other processes.

Computer device and method for reading or writing data by computer 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.
