The periodic message stack in the embodiment is different from the A/B stack arrangement in the prior art, and the single periodic message stack can avoid unnecessary A/B stack switching process in the message modification process.
The periodic message in this embodiment specifically refers to a message that is sent cyclically according to a certain period after configuration is completed. The source of the periodic message is the configuration of the upper layer application software.
In step 100 of this embodiment, the specific sources of the message are:
the initiating message is to control the configuration parameters (configurable periodic message or non-periodic message) of the adding message by upper software, the network controller NC automatically initiates the message after the configuration of the adding message, the periodic message is executed circularly according to the configured period length, and the non-periodic message is executed only once;
after the initiating finger configures the message parameters, the NC automatically starts to send messages to the network terminal;
in this embodiment, if it is determined that the message configuration area does not have a write space, the configuration of the new message parameter is prohibited.
The beneficial effect of this embodiment lies in:
by adding the message configuration area and combining the periodic message A/B stack, the message processing method is simplified, the step of acquiring the CB base address is omitted, and the step of adding the message to the message stack is simpler and is easy for user operation.
According to any of the embodiments described above, in this embodiment: the memory of the network controller is also provided with an aperiodic message stack, a periodic completion queue cache pool and an aperiodic completion queue cache pool;

and when the execution of the cycle message is completed, generating completion state information and storing the completion state information into a cycle completion queue buffer pool.
The aperiodic message in this embodiment specifically refers to a message that is sent only once after configuration is completed. The source of the aperiodic message is the configuration of the upper application software.

Meanwhile, the independence of two different types of messages is enhanced by separating the CQ cache pools of the periodic messages and the non-periodic messages (namely the periodic completion queue cache pool and the non-periodic completion queue cache pool), the unnecessary coupling generated by the CQ cache pool shared by the periodic messages and the non-periodic messages in the prior art is eliminated, and the message processing efficiency is also improved.
According to any of the embodiments described above, in this embodiment:
a data storage space is also deployed in the memory of the network controller;

In this embodiment, the message execution process is described as follows:
the network controller NC initiates a message, which is divided into data transmission and data reception, and both are initiated by the network controller NC first, and the network terminal NT responds. When sending data, the upper layer software stores the data in a data storage area in advance, and the NC sends the data. And when the data is received, after executing a message, the NC stores the data into the data storage area, and the upper layer software fetches data at a corresponding position according to the content of the CQ.
In this embodiment, for the case of multiple processors, the step of temporarily buffering the transmitted data in the data storage space is implemented based on the following pre-steps:
and when the memory is planned, the access position of each processor in the data storage space is specified, and information such as message configuration and the like is prevented from being accidentally tampered.

if the periodic message stack is determined to have the writable space, adding the periodic messages to the periodic message stack according to the configuration sequence;
and if the periodic message stack is determined to have no writable space, performing a set action.
In this embodiment, the action of setting after determining that the writable space does not exist in the periodic message stack includes prohibiting a write operation. That is, no writable space prohibits writing unless other message configurations are deleted to reacquire new space.
The beneficial effect of this embodiment lies in:
by verifying the writable space of the periodic message stack, the reliability and stability of the communication system are further improved.
According to any of the embodiments described above, in this embodiment:

In this embodiment, the index is read, and if it is determined that the periodic message addition is not successful, the periodic message addition is repeated.
It should be noted that the aperiodic message stack is configured to be manually added after a user designates an index, and whether a writable space exists cannot be queried, that is:
after the aperiodic message constructs indexes for users, the CB of the urgent message is written into a CBE space through a host interface according to addresses, and the address calculation formula of the CBE is as follows:
CBE_ADDR(cb_index) =（cb_index-1）* 0x40 + 0x60004000
