Printing History
New editions are complete revisions of the manual. The date on the title page
changes only when a new edition is published.
A software code may be printed before the date; this indicates the version level of
the software product at the time the manual was issued. 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
correspondence between product updates and manual revisions.

The HP 64783A/B Emulator
Description
The HP 64783A/B emulator supports the Motorola 68040, 68EC040, and 68LC040
microprocessors operating at clock speeds up to 33 MHz (HP 64783A) or 40 MHz
(HP 64783B). Differences between the three microprocessors are shown in the
table below:
The emulator uses an MC68040 microprocessor and is pin-for-pin compatible with
the MC68EC040 and MC68LC040 microprocessors. Refer to the end of Chapter 4,
"Using the Emulator", for special considerations when using the emulator in target
systems designed with the MC68EC040 or MC68LC040.
Throughout this manual, the microprocessor will be referred to as the MC68040,
except where the three versions must be discussed separately.
Additionally, this emulator supports development of target systems using the
MC68040 together with up to 31 MC68360’s in slave mode. Refer to the end of
Chapter 4, "Using the Emulator", for an explanation of this emulator’s support for
the MC68360 slave mode.
The emulators plug into the modular HP 64700 instrumentation card cage and offer
80 channels of processor bus analysis with the HP 64704A or HP 64794A
emulation-bus analyzer. Flexible memory configurations are offered from zero
through two megabytes of emulation memory. High performance download is
achieved through the use of a LAN 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 HP workstations. This environment includes an ANSI standard
Motorola Processor Includes MMU Includes FPU

C compiler, assembler/linker, a debugger that uses either a software simulator or
the emulator for instruction execution, the HP Software Performance Analyzer that
allows you to optimize your product software, and the HP Branch Validator for test
suite verification.
If your software development platform is a personal computer, support is 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.
