Abstract
The direct memory access device and method of the present invention uses an event calendar, an expired event queue of a fixed size, a calendar scanner, and an event mover. The event calendar stores an event in a linked list. The expired event queue stores an event that has already expired from the event calendar. The calendar scanner automatically scans the event calendar without management by a central processing unit (CPU). The event mover moves an event from the event calendar to the expired event queue without management by the CPU. The method provides for storing the event in the linked list, automatically scanning the event calendar without management by the CPU, moving the event from the event calendar to an expired event queue of a fixed size without management by the CPU, and storing the event that has already expired from the event calendar.
