1.1. About RealView ICE and RealView Trace

RealView ICE v3.3 is an EmbeddedICE® logic debug solution from ARM® Limited. It enables you to debug software running on:

RealView ICE provides the software and hardware interface between a debugger running on a Windows or Red Hat Linux host computer, and a Joint Test Action Group (JTAG) IEEE Standard 1149.1-2001 port on the target hardware.

RealView ICE also supports a Serial Wire Debug (SWD) connection to the Debug Access Port (DAP). SWD is an alternative protocol to JTAG for connecting to CoreSight™ cores, and has the advantage of requiring fewer pins than previous probes. It also supports higher data rates.

The RealView Trace unit works in conjunction with ARM RealView ICE to provide real-time trace functionality for software running on System-on-Chip (SoC) devices with deeply embedded processor cores that contain the Embedded Trace Macrocell™ (ETM) logic.

You can use RealView ICE and RealView Trace with systems that contain one or more ARM processor cores. RealView ICE also supports the Embedded Trace Buffer (ETB) for capturing small amounts of trace information at high core clock speeds. See Chapter 6 Using RealView Trace and RealView Trace 2 for more information.
