A system, e.g., a system on a chip (SoC) includes a first domain including a first processor configured to boot the system; a second domain including a processing subsystem having a second processor; and isolation circuitry between the first domain and the second domain During boot-up of the system, the first processor provides code to the second domain. When the code is executed by the second processor, it configures the processing subsystem as either a safety domain or as a general-purpose processing domain. The safety domain may an external safety domain or an internal safety domain.

System on a chip with an integrated configurable safety master microcontroller unit

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.
