System for executing, scheduling, and selectively linking time dependent processes based upon scheduling time thereof

摘要

A microcomputer has a processor arranged to share its time between a plurality of concurrent processes. Each process may have means (69) for indicating a time when the process may be executed. The processes may form a linked list of processes (T, U. V) awaiting scheduling for execution. A location (90) is provided for indicating the beginning of a timer list of processes awaiting execution and means (68) is provided for indicating the end of a timer list. The microcomputer may provide more than one timer list of processes of different priority. Each process may include a number of alternative components one or more of which is time dependent.
