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.
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
vi

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.
