After registering the second resource calling operation through the registration interface provided by the single communication queue, the operation ID of the second resource calling operation may also be obtained, so that the corresponding execution result is stored to the memory according to the operation ID of the second resource calling operation.
S103: registering a third resource calling operation through a registration interface provided by the instant messaging queue, and adding the third resource calling operation to the instant messaging queue;
the instant messaging queue is used for storing a third resource calling operation which needs to be executed immediately, such as an operation of performing power-off protection on a target component. An operation creation request can be received before the step, and the operation type of the operation creation request is determined; wherein the operation types include a loop operation, a single operation, and an instant operation; if the operation type of the operation creation request is the instant operation, entering the step of registering a third resource calling operation through a registration interface provided by the instant communication queue, and adding the third resource calling operation to the instant communication queue after registering the third resource calling operation. After registering a third resource calling operation through a registration interface provided by the instant messaging queue, an operation ID of the third resource calling operation may also be obtained, so that a corresponding execution result is stored in a memory according to the operation ID of the third resource calling operation. The present embodiment is not limited to the execution order of S102, and S103, and may be executed sequentially or simultaneously.

The embodiment can register and add the first resource calling operation, the second resource calling operation and the third resource calling operation by using the registration interfaces provided by the communication queues, so as to circularly execute the resource calling operations in the circular communication queues, the single communication queues and the instant communication queues.
As a further introduction to the corresponding embodiment of fig. 1, the resource calling operations in the circular communication queue, the single communication queue, and the instant communication queue may be circularly performed by:
mode 1:

step B3: and B1, executing each second resource calling operation in the single communication queue in sequence, and entering a step B1 after all the second resource calling operations are executed.
Mode 3:

step C3: and C1, executing each third resource calling operation in the instant messaging queue in sequence, and entering the step C1 after all the third resource calling operations are executed.
As a possible implementation manner, the process of sequentially executing each first resource calling operation in the circular communication queue includes: selecting a current first resource calling operation from the circulating communication queue; determining the interval times according to the operation parameters of the current first resource calling operation; judging whether the circulation times of the circulation communication queue are integral multiples of the interval times or not; if yes, executing the current first resource calling operation; if not, the step of selecting the current first resource calling operation from the circular communication queue is entered. Taking the first resource calling operation as an example of the temperature obtaining operation, adding 1 to the current cycle number of all the first resource calling operations in the circular communication queue, wherein the interval number of the operation parameters of the temperature obtaining operation is 8, and if the current cycle number is an integer multiple of 8, executing the temperature obtaining operation.
As a possible implementation manner, in the process of circularly executing the resource calling operations in the circular communication queue, the single communication queue and the instant communication queue, whether the instant communication queue is empty or not can be judged after each first resource calling operation or one second resource calling operation is executed, if not, the resource calling operation in the instant communication queue is executed, and if not, the next resource calling operation is executed according to the original execution sequence.
After executing a first resource calling operation in the circulating communication queue, recording an operation executing position of the circulating communication queue, and sequentially executing each third resource calling operation in the instant communication queue; and after the execution of all the third resource calling operations is finished, continuing to circularly execute the resource calling operations in the circular communication queue, the single communication queue and the instant communication queue from the operation execution position of the circular communication queue.
After executing a second resource calling operation in the single communication queue, recording an operation execution position of the single communication queue, and sequentially executing each third resource calling operation in the instant communication queue; and after the execution of all the third resource calling operations is finished, continuously and circularly executing the resource calling operations in the circulating communication queue, the single communication queue and the instant communication queue from the operation execution position of the single communication queue.
The above procedure is illustrated:
the first resource calling operation of the circular communication queue comprises X1, X2 and X3, and the second resource calling operation of the single communication queue comprises Y1, Y2 and Y3. The cycle sequence is as follows: a circulating communication queue, a single communication queue and an instant communication queue. After executing the X2, if the instant messaging queue is not empty, executing each third resource calling operation in the instant messaging queue, and after all the third resource calling operations are executed, continuing to circularly execute the X3. After executing the X3, if the instant messaging queue is not empty, executing each third resource calling operation in the instant messaging queue, and after all the third resource calling operations are executed, continuing to circularly execute the Y1.
The flow described in the above embodiment is explained below by way of an embodiment in practical application. The present embodiment provides a scheme for maximizing BMC utilization of I2C using an I2C resource manager.
According to the embodiment, the I2C resource manager of the built-in software of the BMC or the external special MCU or the singlechip is used for realizing I2C resource management by the I2C resource manager, so that I2C resources are utilized to the maximum extent, the processes in the BMC are prevented from waiting for the I2C resources, and meanwhile, I2C resources are prevented from idling. The I2C resource manager provides three I2C resource utilization queues, a circulating communication queue, a single communication queue and an instant communication queue. The three queues are all provided with registration interfaces, the I2C actual operation execution logic of the registration parameters and the final queue is distinguished, each operation is registered to generate an operation ID, the operation IDs are mainly used for distinguishing operation and operation results, the I2C resource manager puts the corresponding execution results into a fixed memory according to the operation IDs after the three queues actually execute the I2C operation, each process takes the execution results of the operation registered by the process according to the operation IDs, and the three queue registration parameters comprise modes (read/write/read/write), the length of write data, the written data and the length of read data; the results of the queue execution all include: the operation ID, the length of the read data, the length of the write data, the written data, and the memory stores all of these data in the memory, with the three different queue parameters described below.
The cyclic communication queue is a queue which needs to continuously and circularly perform I2C, and the queue is generally provided with operations which can change in real time, such as operations for acquiring the temperature of a certain device, wherein each operation has interval number setting besides a common parameter, when the number of cyclic access in the cyclic queue is integral multiple of the interval number, the operation can be performed, the interval number is used for adjusting the time interval of some operations, if some information needs to be continuously updated but does not need to be too high, the interval number is adjusted to be larger, and some information needs to be acquired at a high frequency, and the interval number is smaller.
The single communication queue is used for executing the operation which only needs to be acquired once, and the operation after the single acquisition is automatically logged out and cannot be repeatedly executed, for example, some static information only needs to be acquired once and can be put in the whole queue.
The instant messaging queue is a queue for processing operations which need to be processed immediately, if power-off protection and the like are needed to be carried out on a certain component, the priority of the whole queue is highest, the interval for executing the operations of the other two queues can read whether the whole queue is empty or not, if not, the operations of the whole queue are processed preferentially, and the operations of the whole queue are executed and then returned to the original execution queue to be executed continuously.
The three queues of the I2C resource manager are circularly executed, thereby ensuring the hundred percent utilization of the I2C resources, realizing the highest utilization of the I2C resources under the condition of unchanged hardware architecture, solving the problems of low I2C utilization rate and the like in program operation caused by the competing of the I2C resources among various processes, uniformly managing the I2C resources, realizing the separation of software and hardware operation, ensuring that the operation result of the resource manager can not only use memory but also use other media such as a database hard disk and the like, and having good cross-platform portability.
According to the embodiment, the BMC on the server uses the I2C resource manager to remarkably improve the polling frequency of the I2C equipment, and the embodiment can also enhance the I2C resource utilization rate of the BMC, so that the I2C low-cost bus can exert the maximum energy efficiency in the design range, and the cost of replacing the high-speed bus is saved. The embodiment can also be applied to the use management of other serial buses such as USB.
