The HP 64782 Emulator
Description
The Hewlett-Packard Model 64782 emulator supports the Motorola 6833x
microprocessor family. The emulators and supported microprocessors include
HP 64782B/MC68331, HP 64782C/MC68332, HP 64782E/MC68334,
HP 64782G/MC68336, and HP 64782J/MC68338. In this manual, the HP
emulators are referred to by Model Number 64782, and the Motorola
microprocessors are referred to by MC6833x, except where specific information
applies only to certain individual members of the emulator/microprocessor family.
The emulator supports clock speeds up to 33 MHz.
The emulator supports both 5V and 3.3V operation. The emulator has a PGA-style
connector. It can be plugged directly into the PGA connector on the demo board,
and it can be plugged into a PQFP or TQFP target system using optional
accessories.
The emulator plugs into the modular HP 64700 instrumentation card cage and
offers 64 channels of processor bus analysis with the HP 64794A or HP 64704A
emulation-bus analyzer. Up to eight megabytes of emulation memory may be
installed on the probe. High performance download is achieved through the use of
an optional LAN or RS-422 interface. A pair of RS-232 ports and a
firmware-resident interface allow debugging of a target system at remote locations.
For software development, the HP AxCASE environment is available on SUN
SPARCsystems and on HP workstations. This environment includes an ANSI
standard C compiler, assembler/linker, a debugger, the HP Software Performance
Analyzer that allows you to optimize your product software, and the HP Branch
Validator for test suite verification. The C compiler, assembler/linker, and
debugger are also available for MS-DOS systems.
Language support is also available from several third-party vendors. This capability
is provided through the HP 64700’s ability to consume several industry standard
output file formats.
v

Ada language support is provided on HP 9000 workstations by third-party vendors
such as Alsys and Verdix. An Ada application developer can use the HP emulator
and any compiler that generates HP/MRI IEEE-695 to do exhaustive, real-time
debugging in-circuit or out-of-circuit.

In This Book
This manual covers the Hewlett-Packard Model 64782 emulator for the Motorola
MC6833x family of microprocessors. It is divided into the following parts:
Part 1, “Installation,” shows you how to install and connect all of the
emulator/analyzer hardware in the card cage, connect the card cage to a host
computer in several typical configurations, and connect the emulator probe into the
demo board and into your target system.
Part 2, “Service,” shows you how to install and update emulator/analyzer firmware,
solve problems you may encounter while using the emulator/analyzer, and obtain
replacement parts for the emulator/analyzer from Hewlett-Packard.
Part 3, “Terminal Interface Reference,” introduces the interfaces available to use
with the emulator/analyzer, and shows you how to use the terminal interface for the
emulator/analyzer.
This manual replaces the Terminal Interface Reference which accompanied earlier
HP emulators. For information on the Terminal Interface, see Part 3.
You should read the book Concepts of Emulation and Analysis when you have the
chance to do so; it contains a good conceptual introduction to the emulation
process, and also describes how an emulation monitor works. Another book, the
HP 64700 Card Cage Installation/Service Guide, tells you more about installation
and configuration of the HP 64700 Card Cage. If you have a problem with the
emulator and don’t understand how to fix it, a listing of HP Sales and Service
offices is in the Support Services Guide in the back of this binder.

emulator card cage.
The installation tasks are described in the following steps:
1Install optional memory modules on the deep analyzer card, if desired.
2Connect the HP 64782 emulator probe to the HP 64748C emulator control
card.
3Install cards into the HP 64700 card cage.
4Install emulation memory modules on the emulator probe.
5Connect a power cord to the HP 64700 Card Cage.

What you need
Equipment supplied
The minimum system contains:
•HP 64782 6833x PGA Emulator Probe
•Demo target system (shipped with the emulator probe).
•HP 64748C Emulation Control card.
•HP 64794A/C/D Emulation-Bus Analyzer (deep analyzer) card, or
HP 64704A Emulation-Bus Analyzer (1K analyzer) card.
•HP 64700A or HP 64700B Card Cage.
Optional parts are:
•HP 64171A/64172A 256-Kbyte Memory Modules for additional memory
depth.
•HP 64171B/64172B 1-Mbyte Memory Modules for additional memory depth.
•HP 64173A 4-Mbyte Memory Modules for additional memory depth.
•HP 64708A Software Performance Analyzer.
•HP 64701A LAN Interface card (HP 64700A only).
Equipment and tools needed
In order to install and use the MC6833x emulation system, you need:
•Flat-blade screwdriver with shaft at least 5 inches long (13 mm approx).
•Torx T-10 screwdriver (if installing the optional LAN card for the
HP 64700A).
The illustrations in this manual show the HP 64700B Card Cage. The locations of
some components may be slightly different if you are using an HP 64700A Card
Cage.

Antistatic precautions
Printed-circuit boards contain electrical components that are easily damaged by
small amounts of static electricity. To avoid damage to the emulator boards, follow
these guidelines:
•If possible, work at a static-free workstation.
•Handle the boards only by the edges; do not touch components or traces.
•Use a grounding wrist strap that is connected to the HP 64700 chassis.
Note If you already have a modular HP 64700-Series Card Cage and want to remove the
existing emulator and insert an HP 64782 emulator in its place, the
HP 64700-Series generic firmware and analyzer firmware may NOT be
compatible, and the software will indicate incompatibility. In this event, you must
purchase a Flash EPROM board to update the firmware. Instructions for installing
this board and programming it from a PC or HP 9000 are provided in the HP 64700
Card Cage Installation/Service manual. Instructions for installing and updating
emulator firmware are covered in Chapter 5, "Installing/Updating Emulator
Firmware" in this manual.
Note If you already have a modular HP 64700-Series Card Cage and want to remove the
1K analyzer and install the deep analyzer in its place, the analyzer firmware will be
updated by your installation because the analyzer firmware is contained on the
analyzer card.

Step 1. Install optional memory modules on Deep
Analyzer card (if using the Deep Analyzer)
Observe antistatic precautions
With no optional memory modules installed on the deep analyzer card, the trace
memory depth is 8K. If you are going to use the deep analyzer with this default
trace memory depth, skip this step.
1Determine placement of the optional memory modules. Two types of modules may be installed:
256-Kbyte (HP 64172A), and 1-Mbyte (HP 64172B). Either module type may be installed in the banks
on the analyzer card. Do not use HP 64171A/B or HP 64173A memory modules; they are too slow.
If you install no memory modules, the deep analyzer will have 8K maximum memory depth.
If you install four 256-Kbyte memory modules, the analyzer will have 64K maximum memory depth.
If you install four 1-Mbyte memory modules, the analyzer will have 256K maximum memory depth.
If you install a combination of 256-Kbyte memory modules and 1-Mbyte memory modules, the analyzer
will have 64K maximum memory depth. All four connectors must have memory modules installed
before the analyzer depth will be increased.

2To ensure correct installation of optional memory modules on the deep analyzer card, there is a cutout
at one end of the memory modules so they can only be installed the correct way.
To install a memory module:
Align the groove in the memory module with the alignment rib in the connector.
Align the cutout in the memory module with the projection in the connector.
Place the memory module into the connector groove at an angle.
Firmly press the memory module into the connector and make sure it is completely seated.
Rotate the memory module forward so that the pegs on the connector fit into the holes on the memory
module.
Make sure the release tabs at each end of the connector snap around the memory module to hold it in
place.
