Disclosed is a method for controlling an engine control unit which includes at least two microprocessor cores, including steps of executing a parent subtask and at least one child subtask. The method includes the following steps: —determining the number of executables which remain to be executed in the last child subtask of the first period when the parent subtask of the second period starts; and—determining the number of executables already executed in the parent subtask of the second period when the last child subtask of the first period finishes.

Method for controlling a multicore-processor engine control unit

Disclosed is a method for designing an application task architecture for an electronic control unit based on an AUTOSAR operating system that is adaptable to a plurality of microcontrollers. Prior to association with a microcontroller, the method involves developing the application task architecture by using at least one virtual core different from the one or more cores of the microcontroller, the various tasks being assigned respectively to the at least one virtual core, and associating the at least one virtual core with the one or more cores of the microcontroller so as to allocate tasks assigned to the at least one virtual core to the core or among the cores of the microcontroller.
