METHOD FOR REDUCING THE RESPONSE TIME IN A TIME-CONTROLLED OPERATING SYSTEM
The invention relates to a method for shortening the response time in a node computer ( 120 ) of a distributed time-controlled real-time computer system. An operating system task ( 205 ) of the node computer ( 120 ) computes the contents of control registers of the node computer ( 120 ), which characterize the properties of a runtime environment of the application task ( 207 ) in the node computer ( 120 ), prior to a start time ( 213 ), known a priori, of an application task ( 207 ) of the node computer ( 120 ), and writes these contents into the control registers of the node computer ( 120 ).

computing, by an operating system task ( 205 ) of the node computer ( 120 ), the contents of control registers of the node computer ( 120 ), which characterize the properties of a runtime environment of the application task ( 207 ) in the node computer ( 120 ), prior to a start time ( 213 ), known a priori, of an application task ( 207 ) of the node computer ( 120 ), and writes these contents into the control registers of the node computer ( 120 ).
2 . The method according to claim 1 , wherein an initialization task ( 206 ) checks the contents of the control registers of the node computer ( 120 ), which characterize the properties of the runtime environment of the application task ( 207 ), prior to the start time ( 213 ), known a priori, of the application task ( 207 ).

an operating system task ( 205 ) of the node computer ( 120 ) computes the contents of control registers of the node computer ( 120 ), which characterize the properties of a runtime environment of the application task ( 207 ) in the node computer ( 120 ), prior to a start time ( 213 ), known a priori, of an application task ( 207 ) of the node computer ( 120 ), and writes these contents into the control registers of the node computer ( 120 ).
5 . The node computer according to claim 4 , wherein an initialization task ( 206 ) checks the contents of the control registers of the node computer ( 120 ), which characterize the properties of the runtime environment of the application task ( 207 ), prior to the start time ( 213 ), known a priori, of the application task ( 207 ).
