DYNAMIC MULTILEVEL TASK MANAGEMENT METHOD AND APPARATUS

摘要

A method for the orderly execution of multiple tasks in a data processing system and a circuit for implementing that method includes a plurality of task modules (101a, ..., 101n) which construct bids (103a, ..., 103n) based upon the order of the task and its priority. The highest priority highest order number tasks are switched (109) to available system execution resources. The system permits the orderly execution of round-robin task sets in an environment of dynamically changing priorities. When a round-robin task set is interrupted, the system is able to return to the round-robin task set after execution of the higher priority task at the exact point the interruption occurred.
