User manual
Remark: RealMonitor is a configurable software module which enables real time debug.
RealMonitor is developed by ARM Inc. Information presented in this chapter is taken from
the ARM document RealMonitor Target Integration Guide (ARM DUI 0142A). It applies to
a specific configuration of RealMonitor software programmed in the on-chip ROM boot
memory of this device.
Real time debugging.
RealMonitor is a lightweight debug monitor that allows interrupts to be serviced while user
debug their foreground application. It communicates with the host using the DCC (Debug
Communications Channel), which is present in the EmbeddedICE logic. RealMonitor
provides advantages over the traditional methods for debugging applications in ARM
systems. The traditional methods include:
Although both of these methods provide robust debugging environments, neither is
suitable as a lightweight real-time monitor.
Angel is designed to load and debug independent applications that can run in a variety of
modes, and communicate with the debug host using a variety of connections (such as a
serial port or ethernet). Angel is required to save and restore full processor context, and
the occurrence of interrupts can be delayed as a result. Angel, as a fully functional
target-based debugger, is therefore too heavyweight to perform as a real-time monitor.
Multi-ICE is a hardware debug solution that operates using the EmbeddedICE unit that is
built into most ARM processors. To perform debug tasks such as accessing memory or
the processor registers, Multi-ICE must place the core into a debug state. While the
processor is in this state, which can be millions of cycles, normal program execution is
suspended, and interrupts cannot be serviced.
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
