The Navigator Subsystem (NAVSS hardware) is a container which groups together as much as possible the components which provide the Hardare to Software boundary for data movement control in the system. All of the components which control work handoff (queuing, interrupts, monitoring and debugging) are included in the NAVSS which in turn is located as close as possible to the various host processors to which services are provided. Other DMA components such as DRUs, UTC, and PDMAs exist outside the NAVSS but all are controlled by the root complexes provided in NAVSS.
The SoC has two NAVSSes: one in main and one in MCU domain.
