WebJul 13, 2015 · The CoreSight ETB and Embedded Trace Router (ETR) are ATB slaves and connect to the CoreSight system directly to enable capture of trace data on-chip. A TPA, or logic analyzer, must connect to the pins of a trace port that a TPIU drives. Many systems implement either one ETB or one TPIU.

WebJul 6, 2015 · Some R-class processor trace units are unusual in providing a 32 bit ATB interface for instruction trace and a 64 bit ATB interface for data trace. This reflects the high cost of implementing data trace for a high performance processor, and also the need within some real-time application segments to support high-quality data trace capture. river oaks townhomes for rentWeb11.1.
