Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a data transmission method and device, a storage medium and an electronic device. Background Art

[0002] In a multi-processor system, data transmission between processors is usually achieved through various buses and point-to-point transmission methods. Based on the bus transmission architecture, since multiple processors share the bus, bus arbitration is required between the processors. Bus arbitration is not conducive to real-time processing application scenarios, because after the application submits the bus application, it needs to wait for the authorization of the bus arbitration mechanism before occupying the bus for data transmission, and the waiting time is unpredictable for the application.

[0003] Unlike bus transmission, the timing of transmission initiation in point-to-point transmission is completely controlled by the application. Therefore, the transmission time is completely predictable, so that the application can have a reasonable budget for the time between data exchange and data processing, which meets the application requirements of real-time processing. Point-to-point transmission has been applied in the field of real-time processing. However, point-to-point transmission requires the corresponding setting of relevant transmission mode and transmission length parameters at the sending and receiving ends, and requires the sending and receiving ends to make the same settings. This setting is pre-agreed and cannot be changed in real time.

[0004] In the prior art, data transmission usually relies on the characteristics of the TCP transmission protocol. The effects of these characteristics are only effective in the protocol stack of point-to-point connections, and the effects cannot be extended to the application logic based on the protocol stack. For example, a reply message to a command can only confirm that the TCP protocol stack on the other end has received it, but cannot confirm that the application logic on the other end has received the reply message.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

Optionally, as an optional implementation, the data transmission method may be, but is not limited to, applied to: Figure 1 In the environment shown, there are terminal 102, network 110 and terminal 104.

[0033] The receiving end in the terminal 102 receives the data transmission instruction sent by the sending end through the interface, wherein the receiving end and the sending end establish a communication connection Link, and the data transmission instruction is used to transmit data; according to the current state of the connection Link, the method of determining whether the receiving end receives the data reaches the two ends of the connection, without the need for an additional intermediary system, the two ends of the connection can be scheduled independently, each end supports multi-threaded context, and concurrent data communication is carried out, with reliable and asynchronous characteristics, without the need for additional protocol stack context, thereby solving the technical problem in the prior art that the transmission of data at the two ends of the connection requires an intermediary system, resulting in low data transmission efficiency.

The above-mentioned server can be a single server, or it can be a server cluster composed of multiple servers, or it can be a cloud server. The above is only an example, and there is no limitation on this in this embodiment.

[0035] Optionally, as an optional implementation, as Figure 2 As shown, the above data transmission method includes:

[0036] Step S202: The receiving end receives the data transmission instruction sent by the sending end through the interface, wherein the receiving end and the sending end establish a communication connection Link, and the data transmission instruction is used to transmit data.

[0037] Step S204: Determine whether the receiving end receives data according to the current state of the connection Link.

[0038] Optionally, the above-mentioned data transmission method may include but is not limited to mixed communication of data, commands, and events in point-to-point, reliable, synchronous or asynchronous modes, wherein the above-mentioned data may include but is not limited to commands and events, the above-mentioned sending end may be a terminal, and the receiving end may be a terminal, and is applied to the data transmission process in multiple processors.

[0039] Optionally, in this embodiment, determining whether the receiving end receives data based on the current state of the connection Link may include: when the current state of the connection Link is an idle state, the receiving end receives the data sent by the sending end; when the current state of the connection Link is a non-idle state, the data sent by the sending end is placed in a queue.

[0040] Wherein, when the current state of the connection Link is an idle state, the receiving end receives the data sent by the sending end, which may include: setting the current state of the connection Link to a locked state, and the sending end sends the data in the transmission protocol buffer.

[0041] Optionally, in this embodiment, when the current state of the connection Link is an idle state, the receiving end receives the data sent by the sending end, which may include: setting the current state of the connection Link to a locked state, and the sending end wakes up and sends the waiting data.

[0042] The sending end waking up and sending the waiting data may include: when the waiting data is in the transmission protocol buffer or the waiting time of the waiting data is greater than a first predetermined time, the sending end waking up and sending the waiting data.

[0043] It should be noted that the sending end waking up and sending the waiting data may include: when the waiting time of the waiting data is greater than the second time, switching the connection Link to a cache waiting mode until being awakened.

[0044] Optionally, in this embodiment, when the current state of the connection Link is idle, the receiving end receives the data sent by the sending end, which may include: in the process of the receiving end receiving the data sent by the sending end, the connection Link is allowed to be preempted and switched to receive suspension, waiting to be awakened again, directly fetching information from the suspension cache queue, or entering the receive waiting state again.

[0045] Among them, when the current state of the connection Link is idle, after the receiving end receives the data sent by the sending end, it can include: the receiving end sends a response message to the sending end, wherein the response information is used to indicate that the data reception has been completed; wherein, when the connection Link is in a non-idle state, the response information is queued and sent when it is idle.

[0046] Through the example provided by the present application, a receiving end receives a data transmission instruction sent by a sending end through an interface, wherein the receiving end and the sending end establish a communication connection Link, and the data transmission instruction is used to transmit data; according to the current state of the connection Link, a method of determining whether the receiving end receives data is achieved, thereby achieving the establishment of both ends of the connection without the need for an additional intermediary system. Both ends of the connection can be scheduled independently, and each end supports multi-threaded contexts for concurrent data communication, with reliable and asynchronous characteristics, without the need for additional protocol stack contexts, thereby solving the technical problem in the prior art that the transmission of data at both ends of the connection requires an intermediary system, resulting in low data transmission efficiency.

[0047] Optionally, as an optional implementation, as Figure 3 The above data transmission method includes:

[0048] Step S302, the sending end sends a data transmission instruction to the receiving end through the interface, wherein the receiving end and the sending end establish a communication connection Link, and the data transmission instruction is used to send data.

[0049] Step S304: Determine whether the sender sends data according to the current state of the connection Link.

[0050] Through the embodiments provided by the present application, a sending end sends a data transmission instruction to a sending end through an interface, wherein a receiving end and a sending end establish a communication connection Link, and the data transmission instruction is used to send data; a method of determining whether the receiving end receives data is used according to the current state of the connection Link, thereby achieving the establishment of both ends of the connection without the need for an additional intermediary system. Both ends of the connection can be scheduled independently, and each end supports multi-threaded contexts for concurrent data communication, has reliable and asynchronous characteristics, and does not require an additional protocol stack context, thereby solving the technical problem in the prior art that the transmission of data at both ends of the connection requires an intermediary system, resulting in low data transmission efficiency.

[0051] Optionally, the present application also provides an optional embodiment of a data-command-event hybrid communication method. Figure 4 As shown, a flow chart of a method for data-command-event hybrid communication (I) is shown, and the specific details are as follows.

[0052] 0) At a certain moment of a certain Link, T2 or T3 calls the interface SendData, SendCommand or PostEvent to send data, send or post a command or event with ID = X, and data Data = […]. At this time, T1 may have called the RecvData, RecvCommand or WaitEvent interface.

[0053] 1) If the current Link is in "Idle", jump to step 2; if it is in "AckRecving or CmdExecuting" of "Busy Cause", jump to step 6. This type of busy cause is "short type", which means it will be processed quickly; if it is in "DataRecving, CmdRecving or EventWaiting" of "Busy Cause", jump to step 7. This type of busy cause is "long type", which means it is likely to take a long time to receive new information.

[0054] 2) Lock the transmission channel of the Link and execute the sending data, command or delivery event. If the execution fails, typically due to reasons such as disconnection and full sending queue, jump to step 4.

[0055] 3) If successful and ACK is not required (correct command response), jump to step 4 immediately. Otherwise, wait for the ACK of the received command on this link. If the received content does not match, place it in the receive buffer and continue to wait for ACK. If it matches or times out, jump to step 4.

[0056] 4) Unlock the transmission channel of the Link. If the current Link is waiting to send, wake it up to continue sending. Otherwise, check whether the current Link is waiting to receive. If so, wake it up to continue receiving, including processing with receiving buffer.

[0057] 5) End: The SendCommand interface is called on the Link and returns. It may succeed or fail. The reason for the failure may be timeout or other reasons such as link disconnection.

[0058] 6) First, determine whether there is an idle CPU core in Tn of AckRecving. If so, it is worth "busy waiting", or whether Tn of CmdExecuing is running on other CPU cores, that is, whether Tn has other independent CPUs to run during busy waiting. If it is determined to be worth "busy waiting", spin lock waiting is adopted, and the link can be unlocked quickly, thereby reducing task switching. If a signal that the link has been unlocked is received during busy waiting, jump to step 1; if the busy waiting times out, enter "sleep waiting", that is, sleep waiting for the unlock signal to wake up or timeout wake up, and jump to step 1 or step 5 respectively;

[0059] 7) The sub-process switches Link to receive buffer mode, unlocks Link and jumps to step 1.

[0060] like Figure 5 As shown, a method flow chart of data-command-event hybrid communication (II) is described in detail as follows:

[0061] 0) Start: At a certain moment in a certain Link, Tn calls the interface RecvData, RecvCommand or WaitEvent to receive or wait for the data, command or event arriving at this Link.

[0062] 1) If the current Link is in the "Idle" state, jump to step 3.

[0063] 2) First, lock the transmission channel of the Link and start to perform the receiving or waiting operation. If there is already incoming information in the transmission protocol buffer at this time, directly obtain the information in it and go to step 3; otherwise, enter the waiting mode until being awakened, and determine the awakening reason. If there is incoming information, obtain the information, or the awakening reason is timeout. Both of these awakening reasons go to step 3; if the awakening reason is preemption, switch the Link to cache waiting mode until being awakened.

[0064] 3) Unlock the transmission channel of the Link. If there is a task waiting to be sent, wake up the sub-process: Link_Send / Post.

[0065] 4) Same as step 6 of Link_Send / Post.

[0066] 5) The Link already has cached information, and directly obtains these cached commands or events.

[0067] 6) End the receiving or event process of this Link.

[0068] like Figure 6 As shown, a flow chart of a method for data-command-event hybrid communication (II) is described in detail as follows.

[0069] 0) Start: At a certain moment in a certain Link, Tn calls the interface AckCommand or CompleteEvent to confirm or complete the commands that have been executed or the events that have been processed in this Link.

[0070] 1) If it is idle, go directly to step 2; if it is not idle, go directly to step 3.

[0071] 2) Execution: First transmit the Ack or Complete information queued in the queue, and then transmit this Ack or Complete information.

[0072] 3) Queuing: Put the information to be Ack or Complete into the queue and start it when it is free.

[0073] 4) Receive: Complete the transmission of Ack or Complete.

[0074] In this embodiment, (1) when the "busy reason" of the transmission channel is "short type", a spin-type busy wait or task sleep wait is performed, or the link is switched to receive suspension, so that the current task tries to obtain the transmission right of the channel again. The spin-type busy wait first determines whether the current task and the task being waited are running on different CPUs at the same time. Only if concurrent running is satisfied will it be busy wait, otherwise it will directly sleep wait. (2) When the "busy reason" of the transmission channel is "long type", it switches to suspension mode and waits to be awakened. (3) When the current task receives information beyond the expectations of this context, it will assign it to and wake up the receive suspended task. (4) When the task is in the receive state, it can be preempted and switched to receive suspension, waiting to be awakened again, directly taking information from the suspension cache queue, or entering the receive wait state again. (5) When the task confirms and completes the information transmission, if the transmission channel is "busy", it will be directly queued and sent when it is idle.

[0075] Through the embodiments provided in the present application, the above-mentioned data-command-event hybrid communication method has the characteristics of supporting both traditional data sending and receiving, reliable synchronous command execution, and reliable asynchronous event processing. It only requires the context of calling the interface, and does not require the protocol stack context.
