Printing History

New editions are complete revisions of the manual. 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

The HP 64780A Emulator

Description

The HP 64780A emulator supports the Motorola 68360 and 68EN360

microprocessor operating at clock speeds up to 33 MHz. The emulator supports

both 5V and 3.3V operation. The emulator plugs directly into a PGA socket, and it

can be plugged into a PQFP target system using optional accessories.

In this manual, the emulator is referred to by Model Number 64780A, and the

Motorola microprocessor is referred to by MC68360.

The emulator plugs into the modular HP 64700 instrumentation card cage and

offers 80 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

a LAN (standard in the HP 64700B; optional in HP 64700A) or RS-422 interface.

An RS-232 port 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.

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.

Motorola’s initial release of the MC68360 was "Revision A1". HP used that

original version in its first emulator shipments. Since that time, Motorola has

released follow-on versions "B1," "B2," "C," and "MC68MH360". Each

subsequent version fixed errata from the previous version. HP is currently using

33-MHz Revision C in its HP 64780A emulator.

Motorola continues to ship prior revisions of the MC68360, and the MC68MH360.

If you would like to use one of the non-Revision C parts in your HP 64780A

emulator, HP offers an upgrade kit. Contact your local HP field engineer for

ordering information.

Along with the upgrade kit, you will have to supply your own non-Revision C part

(order separately). You will install your non-Revision C part in the processor

socket on the emulator probe by following instructions supplied with the upgrade

kit.

In This Book

This manual covers the HP 64780A emulator for the MC68360 microprocessor. 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.
