The HP 64780A Emulator

Description

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

microprocessor operating at clock speeds up to 25 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.

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

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.

In This Book

This manual shows you how to use the HP 64780A emulator through its Graphical

User Interface for the MC68360 microprocessor. It is divided into the following

parts:

Part 1 contains the Quick Start Guide. It shows you how to quickly become

productive with the emulation system.

Part 2 explains how to accomplish common tasks, often requiring use of several

emulator/analyzer commands together. This part assumes you know how to use the

commands to control the emulator. Instructions are given to help you connect the

emulation probe into a target system, get the desired interface on screen, and use

the emulator/analyzer commands to control the emulation processor while making

emulation measurements. This part also shows you how to use the emulation-bus

analyzer for debugging, use the Software Performance Measurement Tool supplied

with the emulator, and couple two or more emulators to coordinate measurements

involving more than one processor.

Part 3 shows you how to change the appearance or behavior of the Graphical User

Interface, and describes in detail each of the commands available in the

emulator/analyzer, and lists each of the messages you may see while using the

MC68360 emulator/analyzer, along with suggested corrective actions.

Part 4 of this book shows you how to install the Graphical User Interface and

Softkey Interface software, and how to update your emulator/analyzer firmware

with the progflash command, and display current firmware version information.

The Hewlett-Packard M68360 Emulator/Analyzer Installation/Service/Terminal

Interface User’s Guide shows you how to install the emulator hardware into the

card cage, install SRAM modules and covers on the emulation probe, and how to

connect the probe to the demo board and verify performance of the emulation

hardware. It also provides a thorough analysis of possible problems and their

solutions. It also lists the complete specifications and characteristics of the

M68360 emulator. It shows you how to connect the emulator into an MC68360

target system and overcome differences between the specifications and

characteristics of the target microprocessor and those of the emulator.
