Abstract: A method for resetting a so-called System on Chip SoC is described as well as a system adapted and configured to perform the method. A reset signal applied to the SoC resets the system but at the same time prevents loss and corruption of data that was processed at the time of signal application.

Abstract: The disclosure relates to systems and methods for defining a processor safety privilege level for controlling a distributed memory access protection system. More specifically, a safety hypervisor function for accessing a bus in a computer processing system includes a module, such as a Computer Processing Unit (CPU) or a Direct Memory Access (DMY) for accessing a system memory and a memory unit for storing a safety code, such as a Processor Status Word (PSW) or a configuration register (DMA (REG)). The module allocates the safety code to a processing transaction and the safety code is visible upon access of the bus by the module.
