Isolation Of Subsystems On A System On A Chip
A System on a Chip (SoC) includes a plurality of general purpose processors, a plurality of application specific processors, a plurality of SoC support processing components, a security processing subsystem (SCS), a general access Network on a Chip (NoC) coupled to and servicing communications between the plurality of general purpose processors and the plurality of SoC support components, and a proprietary access NoC coupled to and servicing communications for the plurality of application specific processors and the SCS. The SoC may further include a safety processor subsystem (SMS) coupled to the proprietary access NoC, wherein the proprietary access NoC further services communications for the SMS and isolates communications of the SMS from communications of the plurality of general purpose processors. The general access NoC and the proprietary access NoC isolate communications of the SCS and the SMS from communications of the plurality of general purpose processors.
