And step 14, acquiring the level and the type of the interrupt source according to the interrupt source, and executing a corresponding interrupt processing instruction according to the level and the type of the interrupt source.
In the embodiment of the invention, the data transmitted to the node through the optical fiber is obtained. The optical fiber is a channel for transmitting data, has the characteristics of high transmission speed, less data loss and the like, and can transmit a large amount of data to the node in real time. The data is analyzed to obtain the address corresponding to the data, and the purpose of analyzing the data is to find out the address information contained in the data so as to facilitate the subsequent data processing. According to the addresses, the items in the first-level mapping table in the multi-level mapping table are traversed one by one in sequence to obtain matching items, and interrupt sources of corresponding levels are generated. According to the interrupt sources, the levels and types of the interrupt sources are obtained, and corresponding interrupt processing instructions are executed, and the operation can be executed according to different interrupt sources, so that data processing is more targeted.

and step 113, allocating fixed storage positions in each data area according to the value of the storage address and the length corresponding to each address to form a multi-level mapping table with the length of N.
In the embodiment of the invention, the number M of the data areas and the address number N contained in each data area are acquired, so that the overall structure and the scale of the mapping table can be understood, and the conditions are created for subsequent data storage and retrieval. And the required storage space is allocated for each data area and is used for storing at least one address and the length information corresponding to each address, so that each data area can be ensured to have enough space to store the address and the length information, and the loss or confusion of data is avoided. According to the numerical value of the storage address, a fixed storage position is allocated in each data area for each address and the length corresponding to each address, so that a multi-stage mapping table with the length of N is formed, each address and length information can have a fixed position in the mapping table, subsequent data retrieval and use are facilitated, and meanwhile, the efficiency of data retrieval can be further improved through the design of the multi-stage mapping table.

When the system processes a plurality of interrupt sources and mapping items, the system can process according to the priority, and the interrupt sources and the mapping items with high priority are ensured to be processed preferentially. According to the priority of the interrupt sources and the mapping items, the system performs sequencing to obtain an interrupt source and mapping item list according to the order from high priority to low priority, so as to effectively manage and schedule the resources when a plurality of interrupt sources and mapping items exist, and ensure the stable operation of the system. The interrupt sources or the mapping items are selected from the ordered list one by one for processing, and the interrupt sources and the mapping items can be processed sequentially according to the priority, so that the tasks with high priority can be processed preferentially, and the response speed and the processing efficiency of the system are improved.
