DIAGNOSTIC MULTILEVEL POLYMORPHIC STATE MACHINE TECHNICAL FIELD

摘要

A diagnostic polymorphic state machine (12) for a multiprocessor system (15) includes a coordinator state machine (86) controlling diagnostic operations. Multiple node state machines (88) are in communication with the coordinator state machine (86) and perform diagnostic testing on associated task devices. The coordinator state machine (86) and the node state machines (88) are used in a hierarchal manner to enable polymorphic diagnostic testing of the task devices.
