Abstract
A data processing machine comprises a plurality of elementary machines (SUPMS, DEP, ARR, . . . ) disposed in a plurality of levels (level 1, level 2, . . .), and an event presentation device (PTA) responding to the arrival of an event by identifying the lowest machine level that is active and by identifying the elementary machine that is active in this lowest active machine level to present the event to said active elementary machine. An active elementary machine at any intermediate machine level comprises lower level activation means making it possible to respond to certain events by activating the next lower machine level and to activate a lower elementary machine in said lower machine level, and means for responding to certain other events that are not processed by said active elementary machine by sending them up to a higher level, thereby enabling an event to be transferred to an active higher elementary machine in the machine level immediately above the machine level to which said active elementary machine belongs. Said active elementary machine also includes deactivation means enabling it to respond to a particular event by deactivating itself and simultaneously deactivating any lower level elementary machine that it may previously have activated.
