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 – Section 12.7.4
NAVSS0 hardware components and their integration are shows on Figure 10-13.
MCU NAVSS functionality is similar to that of main NAVSS, however it is composed of fewer peripherals and has reduced bandwidth.
