Abstract:
A method for multicore processor fault detection during execution of safety critical software applications in a multicore processor environment involves dedicating the complete resources of at least a part of at least one processor core to execution of diagnostics software application whilst dedicating remaining resources to execution of a safety-critical software application, thereby enabling parallel execution of the diagnostics software application and the safety-critical software application. There is also provided a controller for multicore processor fault detection during execution of safety critical software applications in a multicore processor environment. The controller includes a multicore processor environment. The controller may be part of a control system. The method may be provided as a computer program.
Abstract:
A symmetric multi-core processor arrangement for a safety critical system, including: a symmetric multi-processor having at least two cores and a memory shared for the at least two cores; and a hypervisor connected to the symmetric multi-processor, and configured to organize access to the at least two cores for at least a diagnostic application checking the safety critical system; wherein, during use, the diagnostic application is configured to read from and write to the memory, and the hypervisor is configured to read only from the memory.
