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™

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 (Debug Communications Channel), which is present in the EmbeddedICE

logic. The LPC2290 contains a speciﬁc conﬁguration of RealMonitor software

programmed into the on-chip memory.
