Embodiment Construction
[0024] The concrete implementation scheme of this method is as follows:
[0025] (1) Define the structure for storing real-time event data entities, index nodes, and various management data. For the logical relationship between various structures, see figure 1 .
[0026] An array for storing real-time event entities is defined in SRAM, and each event body defines a common information header, including: event occurrence time, priority reflecting event importance, reference counter and validity flag bit. Define the linked list nodes storing the positions of the front and rear nodes of the doubly linked list in the memory. The real-time event index node contains a linked list node and an index variable, and the value of the index variable is the subscript serial number of the event array in the SRAM area.
[0027] Define a linked memory pool of free index nodes, and use the backward pointers of the linked list nodes in the index nodes to form a singly linked list. A head pointe...
