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
