Product data sheet
6.20.2 Embedded trace
6.20.3 RealMonitor
The ARM core has a Debug Communication Channel (DCC) function built-in. The DCC
allows a program running on the target to communicate with the host debugger or another
separate host without stopping the program flow or even entering the debug state. The
DCC is accessed as a co-processor 14 by the program running on the ARM7TDMI-S
core. The DCC allows the JTAG port to be used for sending and receiving data without
affecting the normal program flow. The DCC data and control registers are mapped in to
addresses in the EmbeddedICE logic.
This clock must be slower than
operate.
Since the LPC2141/42/44/46/48 have significant amounts of on-chip memory, it is not
possible to determine how the processor core is operating simply by observing the
external pins. The Embedded Trace Macrocell (ETM) provides real-time trace capability
for deeply embedded processor cores. It outputs information about processor execution to
the trace port.
The ETM is connected directly to the ARM core and not to the main AMBA system bus. It
compresses the trace information and exports it through a narrow trace port. An external
trace port analyzer must capture the trace information under software debugger control.
Instruction trace (or PC trace) shows the flow of execution of the processor and provides a
list of all the instructions that were executed. Instruction trace is significantly compressed
by only broadcasting branch addresses as well as a set of status signals that indicate the
pipeline status on a cycle by cycle basis. Trace information generation can be controlled
by selecting the trigger resource. Trigger resources include address comparators,
counters and sequencers. Since trace information is compressed the software debugger
requires a static image of the code being executed. Self-modifying code can not be traced
because of this restriction.
RealMonitor is a configurable software module, developed by ARM Inc., which enables
real-time debug. It is a lightweight debug monitor that runs in the background while users
debug their foreground application. It communicates with the host using the DCC, which is
present in the EmbeddedICE logic. The LPC2141/42/44/46/48 contain a specific
configuration of RealMonitor software programmed into the on-chip flash memory.
