The RealView® Trace capture unit is an add-on expansion module to the RealView Ice run control unit. It provides off-chip trace data capture capability for the ARM  Embedded Trace Macrocell TM and CoreSight TM advanced on-chip debug and trace technology. RealView Trace capture module enables non-invasive, real-time tracing of instructions execution and data transactions for all available ARM processors, when used with the RealView Development Suite debug software.

CoreSight Multi-Core Trace
The RealView Trace capture unit enables multiplexed trace streams generated by the CoreSight Trace Funnels to be captured and analyzed by the RealView Development Suite debugger - so developers can carry out non-invasive debug across multiple cores.

Reducing Device Pin Count with CoreSight
The RealView Trace capture unit provides a connection capability to the CoreSight Trace Port Interface Unit - allowing the number of data and control pins for trace to be reduced.
