11.5.4.1. Transaction Buffer Unit Interface

The FPGA initiator can address the DDR/SOC in either virtual or physical address mode. To support virtual addressing, an SMMU (TBU) is inserted between the width adaptation section of the MPFE NOC and the MPFE NOC main ingress port. The FPGA initiator can use physical addressing by bypassing the TBU.
