For example, when the electronic device acquires the data transmission instruction, the electronic device may acquire a socket send () corresponding to the data transmission instruction. The electronic device may also obtain a socket bond () corresponding to the data transfer instruction.
It is easy to understand that when the electronic device obtains the data transmission instruction, the electronic device may obtain the socket corresponding to the data transmission instruction and the shared data corresponding to the data transmission instruction.
S205, calling the socket to transmit the shared data to the daemon through the proxy module;
the specific process is as above, and will not be described here again.
According to some embodiments, daemon refers to a process that runs in the background of the first central processor and is not controlled by any electronic device. The daemon is independent of the controlling electronic device and periodically performs certain tasks or waits to process certain occurring events. The daemon runs without user input and provides some service. The daemon is not specific to a particular fixed process. For example, the daemon may change when the task that the daemon performs changes. The daemon process may also change when the first central processor changes.
In some embodiments, the electronic device invokes the socket send () by controlling the application program controlled by the first central processing unit, so the electronic device may directly transmit the shared data to the daemon usrsock client through the proxy module usrsock.
It is easy to understand that when the electronic device obtains the socket corresponding to the data transmission instruction and the shared data corresponding to the data transmission instruction, the electronic device may invoke the socket to transmit the shared data to the daemon through the proxy module.
S206, the control daemon transmits the shared data to the service process of the second central processing unit through the cross-core communication module set, so that the second central processing unit responds to the data transmission instruction and transmits the shared data to the network equipment based on the physical network card in the second central processing unit;
the specific process is as above, and will not be described here again.
According to some embodiments, the service process refers to a program in the second central processing unit that is automatically completed by the system and does not require interaction with the user. The service process is not specific to a fixed process. For example, a service process may change when the task it performs changes. The service process may also change when the second central processor changes.
For example, when the electronic device transmits the shared data to the daemon usrsock client through the proxy module usrsock, the electronic device may control the daemon usrsock client to transmit the shared data to the service process usrsock server of the second central processor through the cross-core communication module set.
According to some embodiments, when the electronic device controls the daemon to transmit the shared data to the service process of the second central processor through the cross-core communication module set, the electronic device may control the daemon to transmit the shared data to the second asymmetric multi-core communication module of the second central processor through the first asymmetric multi-core communication module, so that the service process where the second asymmetric multi-core communication module is located obtains the shared data. Therefore, the accuracy of the electronic equipment for transmitting the shared data can be improved.
In some embodiments, an asymmetric multi-core communication module refers to a module that handles tasks requiring higher software flexibility with a small number of general purpose processing cores. Meanwhile, the asymmetric multi-core communication module can also adopt a large number of hardware accelerators to process more tasks.
In some embodiments, the first asymmetric multi-core communication module refers to an asymmetric multi-core communication module corresponding to a first central processor in a set of cross-core communication modules. The first asymmetric multi-core communication module is not particularly limited to a certain fixed module. For example, the first asymmetric multi-core communication module may change when the first central processor changes. The first asymmetric multi-core communication module may also change when changing across the set of core communication modules.
In some embodiments, the second asymmetric multi-core communication module refers to an asymmetric multi-core communication module corresponding to a second central processor in the set of cross-core communication modules. The second asymmetric multi-core communication module is not particularly limited to a certain fixed module. For example, the second asymmetric multi-core communication module may change when the second central processor changes. The second asymmetric multi-core communication module may also change when a change occurs across the set of core communication modules.
For example, when the electronic device transmits the shared data to the daemon usrsock client through the proxy module usrsock, the electronic device may control the daemon usrsock client to transmit the shared data to the second asymmetric multi-core communication module OpenAMP2 through the first asymmetric multi-core communication module OpenAMP 1.
It is easy to understand that when the electronic device invokes the socket to transmit the shared data to the daemon through the proxy module, the electronic device may control the daemon to transmit the shared data to the service process of the second central processing unit through the cross-core communication module set, and further, the electronic device may enable the second central processing unit to transmit the shared data to the network device based on the physical network card in the second central processing unit in response to the data transmission instruction.
In the embodiment of the disclosure, the proxy module calling information sent by the second central processing unit is obtained; establishing a socket on the first central processing unit and transmitting the socket to the second central processing unit; therefore, the acquisition efficiency of the socket corresponding to the data transmission instruction can be improved. Acquiring a data transmission instruction through an application program controlled by a first central processing unit; acquiring the socket corresponding to the data transmission instruction and the shared data corresponding to the data transmission instruction; transmitting the shared data to the daemon through the proxy module by calling the socket; the control daemon transmits the shared data to a service process of the second central processing unit through the cross-core communication module set, so that the second central processing unit responds to the data transmission instruction and transmits the shared data to the network equipment based on a physical network card in the second central processing unit; therefore, when data transmission is required through the first central processing unit without the physical network card, the data to be transmitted can be sent to the second central processing unit with the physical network card by adopting the socket and the cross-core communication module set, and then the data can be transmitted to the network equipment through the second central processing unit. Therefore, even if a certain central processing unit in the electronic equipment does not have the network card capability, the network resource can be accessed through the application program controlled by the central processing unit, so that the convenience of network sharing can be improved.
