Printing History
New editions are complete revisions of the manual. The date on the title page
changes only when a new edition is published.
A software code may be printed before the date; this indicates the version level of
the software product at the time the manual was issued. Many product updates and
fixes do not require manual changes, and manual corrections may be done without
accompanying product changes. Therefore, do not expect a one-to-one
correspondence between product updates and manual revisions.

68340 Emulation and Analysis
The HP 64751 68340 emulator replaces 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 can be used with the HP 64704 Emulation Bus Analyzer or the
HP 64794 Deep Memory Emulation Bus Analyzer which capture 80 channels of
emulation processor bus cycle information synchronously with the processor’s
clock signal. This analyzer is called the emulation analyzer.
With the Emulator, You Can ...
•Plug into 68340 target systems with Pin Grid Array (PGA) sockets.
•Download programs into emulation memory or target system RAM.
•Display or modify the contents of processor registers and memory resources.
•Run programs at clock speeds up to 25 MHz (with active probe boards
64751-66508 and higher — up to 16.78 MHz with boards 64751-66506 and
lower), set up software breakpoints, step through programs, and reset the
emulation processor.
With the Analyzer, You Can ...
•Trigger the analyzer when a particular bus cycle state is captured. You can
also trigger the analyzer after a state has occurred a specified number of times.
States are stored relative to the trigger state.
•Qualify which states get stored in the trace.
•Prestore certain states that occur before each qualified store state.
•Trigger the analyzer after a sequence of up to 8 different events have occurred.
•Cause the emulator to stop program execution when the analyzer finds its
trigger condition.

With the HP 64700 Card Cage, You Can ...
•Use the RS-422 capability of the serial port and an RS-422 interface card on
the host computer (HP 98659 for the HP 9000 Series 300) to provide
upload/download rates of up to 230.4K baud.
•Easily upgrade HP 64700 firmware by downloading to flash memory.
With Multiple HP 64700s, You Can ...
•Start and stop up to 16 emulators at the same time (up to 32 if modifications
are made).
•Use the analyzer in one HP 64700 to arm (that is, activate) the analyzers in
other HP 64700 card cages or to cause emulator execution in other HP 64700
card cages to break.
•Use the HP 64700’s BNC connector to trigger an external instrument (for
example, a logic analyzer or oscilloscope) when the analyzer finds its trigger
condition, or you can allow an external instrument to arm the analyzer or break
emulator execution.
With the Graphical User Interface, You Can ...
•Use the emulator and analyzer under an X Window System that supports
OSF/Motif interfaces.
•Enter commands using pull-down or pop-up menus.
•Enter, recall, and edit commands using the command line pushbuttons.
•Enter file names, recalled commands, recalled values, etc., using dialog boxes.
•Set breakpoints by pointing the mouse cursor on a line in the mnemonic
memory display and clicking.
•Create action keys for commonly used commands or command files.
With the Softkey Interface, You Can ...
•Use the emulator and analyzer with a terminal or terminal emulator.
•Quickly enter commands using softkeys, command recall, and command
editing.
