[0055] like Figure 1 As shown, Figure 1 A flow chart of an inter-core communication method provided in an embodiment of the present disclosure. The method includes the following steps S101 to S103:

[0056] S101, reading information sent by the target kernel.

[0057] In some embodiments, the target core is a Cortex-A core. The information includes a start command, an end command, and a first count value of the target core. The start command is used to instruct to send all SOA signals to the Cortex-A core; the end command is used to instruct to stop sending SOA signals to the Cortex-A core; and the first count value is used to indicate whether the working state of the target core is abnormal.

[0058] The disclosed embodiment is applied to the Cortex-M core, and the Cortex-M core periodically reads the information sent by the Cortex-A core after power-on. It can be understood as the heartbeat mechanism of the Cortex-M core and the Cortex-A core. It should be noted that the Cortex-M core starts earlier than the Cortex-A core and starts running earlier. The disclosed embodiment uses the Cortex-A core as the main core and the Cortex-M core as the slave core, and is applied to the Cortex-M core. Step S101 specifically reads the information sent by the Cortex-A core.

[0059] In some embodiments, the method can be applied after the Cortex-M core is powered on and initialized to achieve the first setting of the communication state; it can also be applied to the process in which the Cortex-M core is communicating with the target core, and the communication state in which the Cortex-M core is communicating with the target core is defined as the initial communication state. The Cortex-M core realizes the conversion of the communication state by reading information, wherein the initial communication state is any one of the start state (start), wait state (wait), ready state (ready), retry state (retry), and stop state (stop).

[0060] S102: Determine a target communication state with a target kernel according to the information.

[0061] The target communication state is a preset communication state that corresponds to the information; the preset communication state includes a start state, a wait state, a ready state, a retry state, and a stop state.

[0062] In some embodiments, the correspondence between information and preset communication states is defined in advance, and different information corresponds to different communication states. Optionally, if the information is a start command, the target communication state is the start state; if the information is a stop command, the target communication state is the stop state. If the information is the first count value of the target kernel, the target communication state is determined in the following two optional implementations:

[0063] (1) Implementation Method 1

[0064] If the information is the first count value of the target kernel, step S102 determines the target communication state of the target kernel according to the information, including: obtaining a second count value, comparing the first count value with the second count value; and determining that the target communication state is a ready state when the first count value is equal to the second count value.

[0065] Specifically, if the information sent by the target core is its first count value, the Cortex-M core first obtains the second count value of the core, and the second count value is used to indicate whether the working state of the Cortex-M core is abnormal; then the first count value and the second count value are compared to determine whether the first count value is equal to the second count value. When the first count value is equal to the second count value, it indicates that the working states of the target core and the Cortex-M core are normal and data transmission can be performed, and the target communication state is determined to be a ready state.

[0066] (2) Implementation Method 2

[0067] If the information is the first count value of the target core, step S102 determines the target communication state of the target core according to the information, including: obtaining the second count value, comparing the first count value with the second count value; and determining that the target communication state is a waiting state when the first count value is not equal to the second count value.

[0068] Specifically, if the information sent by the target core is its first count value, the Cortex-M core first obtains the second count value of the core, and then compares the first count value with the second count value to determine whether the first count value is equal to the second count value. When the first count value is not equal to the second count value, it indicates that the working status of the target core and the Cortex-M core is abnormal, and data transmission cannot be performed, and the target communication state is determined to be a waiting state.

[0069] In some embodiments, when the target communication state is a waiting state, the holding time of the waiting state is recorded; when the holding time is longer than a preset time, the waiting state is switched to a retry state to update the target communication state to a retry state. The preset time may be 100ms, which is not specifically limited in the present disclosure.

[0070] Specifically, the duration that the Cortex-M core is in the waiting state is recorded, and when the recorded duration is greater than a preset duration, it is determined that the target communication state is updated to the retry state.

[0071] In some embodiments, the target communication state is determined in combination with the initial communication state of the Cortex-M core to achieve the conversion of the communication state. Optionally, step S102 determines the target communication state of the target core according to the information, including: determining the target communication state that meets the preset conditions according to the information, the information is read in the initial communication state;

[0072] The preset conditions include any of the following:

[0073] The initial communication state is a start state, and the target communication state is one of a start state, a wait state, a ready state, and a stop state;

[0074] The initial communication state is a ready state, and the target communication state is one of a start state, a wait state, a ready state, and a stop state;

[0075] The initial communication state is a waiting state, and the target communication state is one of a starting state, a waiting state, a ready state, a retry state, and a stop state;

[0076] The initial communication state is a retry state, and the target communication state is one of a start state, a wait state, a ready state, and a stop state;

[0077] The initial communication state is the stop state, and the target communication state is one of the start state and the stop state.

[0078] In the above embodiment, when the initial communication state of the Cortex-M core is the start state, it can be converted to one of the start state, the wait state, the ready state, and the stop state. The specific conversion is determined according to the information sent by the target core. For example, when the initial communication state is the start state, the information read is a stop command, and the communication state of the Cortex-M core is switched from the start state to the stop state. For another example, when the initial communication state is the start state, the information read is a start command, and the communication state of the Cortex-M core remains in the start state.

[0079] Exemplarily, when the initial communication state is the start state, if the information read is the first count value of the target core, and the first count value is equal to the second count value, the communication state of the Cortex-M core is switched from the start state to the ready state; if the information read is the first count value of the target core, but the first count value is not equal to the second count value, the communication state of the Cortex-M core is switched from the start state to the waiting state.

[0080] In the above embodiment, when the initial communication state of the Cortex-M core is the ready state, it can be converted to one of the start state, the wait state, the ready state, and the stop state. The specific conversion is determined according to the information sent by the target core. For example, when the initial communication state is the ready state, the information read is a stop command, and the communication state of the Cortex-M core is switched from the ready state to the stop state. For another example, when the initial communication state is the ready state, the information read is a start command, and the communication state of the Cortex-M core is switched from the ready state to the start state.

[0081] Exemplarily, when the initial communication state is the ready state, if the information read is the first count value of the target core, and the first count value is equal to the second count value, the communication state of the Cortex-M core remains in the ready state; if the information read is the first count value of the target core, but the first count value is not equal to the second count value, the communication state of the Cortex-M core is switched from the ready state to the waiting state.

[0082] In the above embodiment, when the initial communication state of the Cortex-M core is the waiting state, it can be converted to one of the starting state, waiting state, ready state, retry state, and stop state. The specific conversion is determined according to the information sent by the target core. For example, when the initial communication state is the waiting state, the information read is a stop command, and the communication state of the Cortex-M core is switched from the waiting state to the stop state. For another example, when the initial communication state is the waiting state, the information read is a start command, and the communication state of the Cortex-M core is switched from the waiting state to the starting state.

[0083] Exemplarily, when the initial communication state is a waiting state, if the information read is the first count value of the target core, and the first count value is equal to the second count value, the communication state of the Cortex-M core is switched from the waiting state to the ready state; if the information read is the first count value of the target core, but the first count value is not equal to the second count value, the communication state of the Cortex-M core remains in the waiting state.

[0084] It should be emphasized that when the initial communication state of the Cortex-M core is the waiting state, the length of time the waiting state is maintained will be recorded so as to further convert to the retry state when the length of time exceeds the preset length of time.

[0085] In the above embodiment, when the initial communication state of the Cortex-M core is the retry state, it can be converted to one of the start state, the wait state, the ready state, and the stop state. The specific conversion is determined according to the information sent by the target core. For example, when the initial communication state is the retry state, the information read is a stop command, and the communication state of the Cortex-M core is switched from the retry state to the stop state. For another example, when the initial communication state is the retry state, the information read is a start command, and the communication state of the Cortex-M core is switched from the retry state to the start state.

[0086] Exemplarily, when the initial communication state is the retry state, if the information read is the first count value of the target core, and the first count value is equal to the second count value, the communication state of the Cortex-M core is switched from the retry state to the ready state; if the information read is the first count value of the target core, but the first count value is not equal to the second count value, the communication state of the Cortex-M core is switched from the retry state to the waiting state.

[0087] In the above embodiment, when the initial communication state of the Cortex-M core is the stop state, it can be converted to one of the start state and the stop state. The specific conversion is determined according to the information sent by the target core. For example, when the initial communication state is the stop state, the information read is the start command, and the communication state of the Cortex-M core is switched from the stop state to the start state. For another example, when the initial communication state is the stop state, the information read is the stop command, and the communication state of the Cortex-M core remains in the stop state.

[0088] Exemplarily, as shown in Table 1, Table 1 is a communication state transition table provided in an embodiment of the present disclosure.

[0089] Table 1

[0090]

[0091] The above-mentioned embodiment determines the corresponding target communication state according to the specific content of the information sent by the target kernel, clearly defines various communication states and the transition conditions between communication states, realizes precise control of the behavior of the multi-core processor system, ensures that the system can run correctly in different communication states, reduces the occurrence of errors and failures, and has strong reliability.

[0092] S103: In the target communication state, process the SOA signal according to a preset method.

[0093] The preset mode corresponds to the target communication state. The preset mode includes: (1) sending all SOA signals; (2) sending a changed SOA signal, where the changed SOA signal is different from the SOA signal transmitted at the historical moment; (3) not sending any SOA signal and waiting for the target core to send new information; (4) sending a reminder signal to the target core, where the reminder signal is used to remind the target core to resend the first count value; (5) stopping sending the SOA signal.

[0094] In some embodiments, a correspondence between the communication state and the preset mode is set in advance. Optionally, if the communication mode is a start state, the preset mode is to send all SOA signals; if the communication state is a preparation state, the preset mode is to send a changed SOA signal; if the communication state is a waiting state, no SOA signal is sent, and the target core is waited for to send new information; if the communication state is a retry state, a reminder message is sent to the target core; if the communication state is a stop state, the sending of SOA signals is stopped.

[0095] In some embodiments, when the target communication state is the start state, step S103 of processing the SOA signal in a preset manner in the target communication state includes: in the start state, transmitting all SOA signals to the target core.

[0096] In some embodiments, when the target communication state is a stop state, step S103 of processing the SOA signal in a preset manner in the target communication state includes: in the stop state, stopping transmitting the SOA signal to the target core.

[0097] In some embodiments, when the target communication state is the preparation state, step S103, in the target communication state, processing the SOA signal in a preset manner includes: in the preparation state, transmitting the changed SOA signal to the target core. It should be emphasized that in the preparation state, the Cortex-M core no longer sends all SOA signals to the target core, but filters the unchanged and useless SOA signals, and then transmits the changed SOA signals to the target core, thereby reducing unnecessary repeated signal transmission and improving the efficiency of inter-core communication.

[0098] In some embodiments, when the target communication state is a waiting state, step S103, in the target communication state, processing the SOA signal in a preset manner includes: in the waiting state, waiting for the target core to transmit new information. In this process, the Cortex-M core no longer transmits any SOA signal to the target core, waiting for the target core to transmit new information to switch to a new communication state. If no new information is received within the preset time, the waiting state is switched to the retry state to update to the retry state.

[0099] In some embodiments, when the target communication state is a retry state, step S103, in the target communication state, processing the SOA signal in a preset manner includes: in the retry state, sending a reminder signal to the target core to remind the target core to resend the first count value. The present disclosure provides a retransmission mechanism to remind the target core to resend the first count value in the retry state, thereby ensuring that the target core is working normally, thereby updating to other communication states, realizing inter-core data transmission, and ensuring the stability and reliability of inter-core communication.

[0100] On the basis of the above embodiments, the present disclosure uses the Cortex-A core as the master core and the Cortex-M core as the slave core under the technical background that the startup time of the Cortex-A core and the Cortex-M core are inconsistent. The inter-core communication method is applied to the Cortex-M core. First, the information sent by the Cortex-A core is read to obtain the commands and instructions of the Cortex-A core. According to the information, the target communication state of the Cortex-M core and the Cortex-A core for communication is determined. The target communication state can be one of the start state, the wait state, the preparation state, the retry state, and the stop state. Each communication state corresponds to a different signal processing method. Further, the Cortex-M core processes the SOA signal in a preset manner under the target communication state, which is suitable for the SOA structure, so that the Cortex-M core and the Cortex-A core can quickly establish a connection after startup, and perform stable and secure inter-core information transmission.

[0101] like Figure 2 As shown, Figure 2 A schematic diagram of the structure of an inter-core communication device is provided for an embodiment of the present disclosure, and the device includes:

[0102] The reading module 201 is used to read the information sent by the target kernel;

[0103] A determination module 202, configured to determine a target communication state with a target core according to the information, wherein the target communication state is a preset communication state corresponding to the information;

[0104] The processing module 203 is used to process the service-based software architecture SOA signal in a preset manner under the target communication state, and the preset manner corresponds to the target communication state.
