6833x Emulation and Analysis
The HP 64782 6833x emulators replace the microprocessor in your
embedded microprocessor system, also called the
target system , so that you
can control execution and view or modify processor and target system
resources.
The emulator requires an emulation analyzer that captures 64 channels of
emulation processor bus cycle information synchronously with the
processor’s clock signal. The HP 64703 Emulation Bus Analyzer meets this
requirement.
The HP 64703 Emulation Bus Analyzer also has an an external analyzer that
captures up to 16 channels of data external to the emulator. You can also use
the HP 64704 or HP 64794 Emulation Bus Analyzer which has 80 channels;
however, these analyzers do not have external analysis channels.
With the Emulator, You Can ...
•
Plug into 6833x target systems.
•
Download programs into emulation memory or target system RAM.
•
Display or modify the contents of processor registers and memory
resources.
•
Run programs, set up software breakpoints, step through programs, and
reset the emulation processor. For information about your emulator clock
speed, refer to the
6833x Installation/Service/Terminal Interface Guide .
With the Analyzer, You Can ...
•
Trigger the analyzer when a particular bus cycle state is captured. States
are stored relative to the trigger state.
•
Qualify which states get stored in the trace.
•
Prestore certain states that occur before each normal store state.
•
Trigger the analyzer after a sequence of up to 8 events have occurred.
•
Capture data on signals of interest in the target system with the external
analyzer.
•
Cause emulator execution to break when the analyzer finds its trigger
condition.
