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.

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.

Features

HP 64782 Emulator

•Active probe emulator; supports the fastest processor speeds currently

available. At the time this manual was printed, the emulator had been tested to

the following processor speeds:

–20 MHz for MC68331, MC68332, and MC68334.

–16 MHz for MC68336 and MC68338.

•5V and 3.3V operation

•No wait states to target memory

•Fast termination cycles to target memory

•Unlimited software breakpoints

•Symbolic support

•36 inch cable and 219 mm (8.8") x 102 mm (4") probe

•Background and foreground monitors

•Simulated I/O with workstation interfaces

•Consumes IEEE-695, HP-OMF, Motorola S-Records, and Extended Tek Hex

File formats directly. (Symbols are available with IEEE-695 and HP-OMF

formats.)

•Multiprocessor emulation

–synchronous start of 32 emulation sessions

–cross triggerable from another emulator, logic analyzer, or oscilloscope

•Demo board and self test module included

Emulation-bus analyzer

•64-channel emulation-bus analyzer

•Post-processed dequeued trace with symbols

•Eight events, each consisting of address, status, and data comparators

•Events may be sequenced eight levels deep and can be used for complex

trigger qualification and selective store

Emulation memory

•Up to 8 Mbytes of emulation memory

•All emulation memory is dual-ported

•Mapping resolution is 256 bytes

•The wait states required for emulation memory depend on processor speed and

the access speeds of the SIMMs installed on the emulation probe, as shown

below:

SIMM Access Speed Runs with no Wait

States Requires 1 Wait State

35 nSEC 0 to 16.78 MHz 16.78 MHz to 25 MHz

20 nSEC 0 to 25 MHz 25 MHz to 33 MHz

25 nSEC 0 to 22 MHz 22 MHz to 30 MHz

•Fast termination cycles to emulation memory are supported up to 10 MHz

when using 20-nSEC and 25-nSEC SIMMs, and supported up to 8 MHz when

using 35-nSEC SIMMs

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.
