A method for executing safety-relevant and non-safety-relevant software components on a hardware platform comprising a computer, memory and a monitoring component that operates independently of the computer. The safety-relevant software component erects a memory protection against access of a non-safety-relevant function to at least one area of the memory of the safety-relevant function before execution of the non-safety-relevant software component, so that the non-safety-relevant software component does not have access to the areas of the memory being used for safety-relevant components. After the return from the non-safety-relevant component, the memory protection is deactivated and the monitoring function monitors the safety-relevant function for its proper operation.

Method for executing security-relevant and non-security-relevant software components on a hardware platform

A method for establishing communication schedules for a distributed real-time computer system comprising nodal computers, wherein: a) a grid (RAS) is created, which contains all of the parameters necessary to enable basic communication between nodes (KR. . . KR) of a cluster (CLU); b) nodal communication schedules (KPG; KP, KP) for all nodes planned to be used as invariant components (KR; KR, KR) are derived from the grid (RAS) and all parameters of the grid are copied and node-specific parameters are added; and c) cluster communication schedules (CP, CP; CL, CL) are derived from the nodal communication schedules (KPG; KP, KP), which contain, in addition to all parameters of the grid and the node-specific parameters of the invariant components, those parameters which are relevant to the remaining nodes of the cluster.
