8.1 System Bus and Interconnect

The device on-chip interconnect is architectured around the following components:

  • 5x AXI matrixes based on the Arm NIC-400 module
  • 1x AHB matrix
  • 8x APB buses
  • 1x Universal DDR Memory Controller (UDDRC)

The following features are supported by the interconnect backbone:

  • Quality of Service (QoS) to ensure priorities and limits for all AXI and AHB transactions
  • Performance monitoring to track AXI bus activity
