摘要： This application provides a data transmission method and system, to improve data transmission efficiency. The data transmission method provided in this application is an implementation method used when a plurality of communications submodules communicate in a parallel manner. A second communications submodule in the plurality of communications submodules sends, to a hardware queue, data that needs to be sent to a first communications submodule. The first communications submodule obtains the data from the hardware queue when a state of writing data into the hardware queue is triggered. The hardware queue may be a hardware queue in a first processor for running the first communications submodule or a hardware queue in a second processor for running the second communications submodule. In the method, the second submodule does not need to send a notification message to the first submodule to indicate that data has been sent, to reduce a delay of communication between the second submodule and the first submodule, thereby improving communication efficiency.
