Main SoC Navigator Subsystem (NAVSS0) consists of DMA/Queue Management components – UDMA and Ring Accelerator (UDMASS), Peripherals (Module subsystem [MODSS]), Virtualization translation (VirtSS), and a North Bridge (NBSS).
UDMASS – UDMASS is the essential part of the TI Data Movement Architecture (see Section 10.1). UDMASS consists of:
MODSS – Module subsystem is a collection of peripherals with different system-level functions, for example, interprocessor communication and time sync, among others. NAVSS0 contains the following modules:
NBSS – North bridge – Section 10.2.10
VirtSS – Virtualization sub-system provides all the translation components supported in K3 for virtualization:
ECC aggregators
NAVSS0 hardware components and their integration are shows on Figure 10-14.
Diagram is a high level representation of the Main NAVSS module, not all connections are shown.
MCU NAVSS functionality is similar to that of main NAVSS, however it is composed of fewer peripherals and has reduced bandwidth.
