A method for scheduling tasks to a cyclic schedule, comprising maintaining a request queue, a count, the count being initialized to a given limit, and an index of a current time slot within the schedule. Periodically, if the request queue contains a reference to an urgent task among the tasks, that reference is removed from the request queue and the urgent task is dispatched and if the request queue is empty, the index is advanced to the next time slot within the schedule. If the next time slot is statically assigned to a task among the tasks, that task is dispatched, and if the next time slot is unassigned and the count is below the limit, the count is incremented and the index is further advanced to the next but one time slot.

A method for securing an application programming interface of a utility program library, including at least one program construct, of a hypervisor, including a configuration of the hypervisor that assigns at least one permissible call of the program construct to at least one guest system of the hypervisor, and a code generation, supported by the configuration, of a declaration of the program construct adapted to the guest system.

Method and device for securing the application programming interface of a hypervisor

A method for creating a hypervisor unit for a control unit is described. The hypervisor unit is designed to execute two applications on the control unit during a run time. The hypervisor unit is created during a compile time as a function of a first property of the first application, as a function of a second property of the second application, and as a function of a third property of the control unit.

Method for hosting a multitasking guest on a host system, wherein the guest is allocated a periodic execution server and a deferrable execution server associated with a partition of the system, event-driven tasks of the guest are assigned to the deferrable execution server, time-driven tasks of the guest are assigned to the periodic execution server, a hypervisor of the execution servers is assigned to a first priority group of the system, the deferrable execution server is assigned to a second priority group of the system, the periodic execution server is assigned to a third priority group of the system, and a preemptive task scheduler maintains a descending priority order among the priority groups while the execution servers execute the tasks concurrently.

A method for the on-board diagnosis of a control unit which include a hypervisor and at least one guest system operated under the hypervisor. In the method, the guest system receives a diagnosis inquiry at an individual diagnosis address of the guest system from a diagnostic tool with the aid of a communication infrastructure. The guest system makes a self-diagnosis. The guest system receives a hypervisor diagnosis from the hypervisor. The guest system transmits, at its diagnosis address, the self-diagnosis or the hypervisor diagnosis to the diagnostic tool as a function of the diagnosis inquiry.

A method of bypassing an AUTOSAR software component of an AUTOSAR software system including two or more AUTOSAR software components connected via a runtime environment (RTE). To get a high flexibility and a close relationship to the AUTOSAR model of development an custom AUTOSAR software component is used to bypass all or part of the functionality of a selected AUTOSAR software component and provide that functionality to another AUTOSAR software component candidate or on some external system.
