RealMonitor combines features and mechanisms from both Angel and Multi-ICE to
provide the services and functions that are required. In particular, it contains both the
Multi-ICE communication mechanisms (the DCC using JTAG), and Angel-like support for
processor context saving and restoring. RealMonitor is pre-programmed in the on-chip
ROM memory (boot sector). When enabled It allows user to observe and debug while
parts of application continue to run. Refer to

21.3.1 RealMonitor components

As shown in

21.3.2 RMHost

This is located between a debugger and a JTAG unit. The RMHost controller,
RealMonitor.dll, converts generic Remote Debug Interface (RDI) requests from the
debugger into DCC-only RDI messages for the JTAG unit. For complete details on
debugging a RealMonitor-integrated application from the host, see the ARM RMHost User
Guide (ARM DUI 0137A).

21.3.3 RMTarget

This is pre-programmed in the on-chip ROM memory (boot sector), and runs on the target
hardware. It uses the EmbeddedICE logic, and communicates with the host using the
DCC. For more details on RMTarget functionality, see the RealMonitor Target Integration
Guide (ARM DUI 0142A).
