Embedded Trace Router
The ETR can route trace data to the HPS on-chip RAM, the HPS SDRAM, and any memory in the FPGA
fabric connected to the HPS-to-FPGA bridge. The ETR receives trace data from the AMBA Trace Bus
Replicator. By default, the buffer to receive the trace data resides in SDRAM at offset 0x00100000 and is
32 KB. You can override this default configuration by programming registers in the ETR.

AMBA Trace Bus Replicator

The AMBA Trace Bus Replicator broadcasts trace data from the ETF to the ETR and TPIU.

Trace Port Interface Unit
The TPIU is a bridge between on-chip trace sources and an off-chip trace port. The TPIU receives trace
data from the Trace Bus Replicator (Replicator) and drives the trace data to a trace port analyzer.
The trace output from the TPIU is software programmable and can be set to either 8 or 32 bits wide. The
trace output is routed to an 8-bit HPS I/O interface and a 32-bit interface to the FPGA fabric. The trace
data sent to the FPGA fabric can be transported off-chip using available serializer/deserializer (SERDES)
resources in the FPGA.

Embedded Cross Trigger System
The ECT system provides a mechanism for the components listed in "Features of the CoreSight Debug and
Trace" to trigger each other. The ECT consists of the following modules:
• Cross Trigger Interface (CTI)
• Cross Trigger Matrix (CTM)
