In described examples, a method of operating a system on chip (SoC) includes the following steps. Receive a component description that describes connections among circuit elements of the SoC. Receive a list of specified peripherals to activate while the SoC boots. Receive a hint data that describes a bypass mode clock frequency of a phase locked loop (PLL) of the SoC. Determine an operational data in response to the component description, the hint data, and the specified peripherals. The operational data specifies a subset of the circuit elements required to make the specified peripherals operational. Initialize, and limit the initializing, to the subset of the circuit elements.

Integrated circuit with accelerated boot to priority function

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.
