15.5.2.7. Embedded Trace Router (ETR)

The ETR can be used to take the ATB trace data packets coming in and push them out the AXI interface to the PSS NoC to provide a path for trace data packets to be stored in HPS RAM such as DDR. Since the underlying PSS NOC architecture supports 64-bit data transfers, an ATB upsizer increases the 32-bit ATB bus to 64-bits, and the ETR’s AXI interface configures for 64-bit data.
