2.2.4. System Interconnect

The system interconnect consists of the main L3 interconnect, SDRAM L3 interconnect, and level 4 (L4) buses. The system interconnect is based on the Arteris* FlexNoC* network-on-chip (NoC) interconnect module. The system interconnect incorporates configurable secure firewalls protecting each peripheral.

The L4 buses are each connected to a master in the main L3 interconnect. Each L4 bus is 32 bits wide and is connected to multiple slaves. Each L4 bus operates on a separate clock source.

The SDRAM L3 interconnect consists of the SDRAM adapter and the SDRAM scheduler. SDRAM is protected by firewalls in the SDRAM L3 interconnect.
