Abstract: A system on a chip (SoC) includes a first domain comprising a first processor configured to boot the SoC, and a first debug subsystem, a second domain comprising a second processor, the second domain configurable as either a safety domain or a general-purpose processing domain, and isolation circuitry between the first domain and the second domain. During boot-up of the SoC, the first processor provides code to the second domain which, when executed by the second processor, configures the second domain as either a safety domain or as a general-purpose processing domain.
