PreprocessorInterface

The HP E2465A Preprocessor Interface -
At a Glance
The HP E2465A Preprocessor Interface provides a complete interface
for state or timing analysis between any PowerPC 604 PGA target
system and the following HP logic analyzers:
• HP l 660A/ASIC/CS
• HP 1670A/D
• HP 16550A (two cards)
• HP 16554A (two or three cards)
• HP 16555A/D (two or three cards)
• HP 16556A/D (two or three cards)
The preprocessorinterface provides the physical connection between
the target microprocessor and the logic analyzer. The configuration
software on the flexible disk sets up the logic analyzer for
compatibilitywith the preprocessor interface. The inverse assembler
allows you to obtain displays of the microprocessor operations in
PowerPC 604 mnemonics.
For additional information on the supported logic analyzers or
microprocessors, refer to the appropriate reference manuals for those
products.

In This Book
This book is the user's guide for the HP E2465A Preprocessor Interface. It
assumes that you have a working knowledge of the logic analyzer used and
the microprocessor being analyzed.
This user's guide is organized into three chapters:
Chapter 1explains howto attach the preprocessor to the target
system and logic analyzer, and how to load the preprocessorinterface
software into thelogic analyzer.
Chapter 2 provides reference information on the format specification
and symbols configured by the preprocessorinterface software, and
information about the inverse assemblers and status encoding.
Chapter 3 contains referenceinformation on the preprocessor
interface hardware, including the characteristics and signal mapping
for the preprocessorinterface.
Appendix A contains information on troubleshooting problems or
difficulties which may occurwith the preprocessor interface.
Formore information on the logic analyzers or microprocessor, referto the
appropriate referencemanualfor those products.

Before You Begin
This section lists the logic analyzers supported by the HP E2465A and
provides other information about the analyzers and the preprocessor
interface.
Equipment Supplied
• The preprocessor interface circuit board.
• The configuration and inverse assembler software on a 3.5-inch disk.
• Configuration software for the HP 16505A Prototype Analyzer on a
3.5-inch disk.
• A 287-pin PGA plastic pin protector/extender socket (HP part
number 1200-1975).
• This User's Guide.
The preprocessor interface socket assembly pins are covered for shipmentwith
a conductive foam wafer or conductive plastic pin protector. This is done to
protectthe delicate gold-plated pins from damage due to impact. When you're
not using the preprocessor interface, protectthe socket assembly pins from
damage by covering them with the pin protector.

Before You Begin
Minimum Equipment Required
• The HP E2465A preprocessorinterface.
• The configuration and inverse assembler software.
• One of the logic analyzers listed in the table below. For the
mainframe logic analyzers, an HP 16500B or HP 16500C mainframe
is required.
For the HP 16500B mainframe, software revision 3.4 or higher is
recommended. For the HP l 6500C mainframe, software revision 1.0
or higheris recommended.

Connecting to the Target System
Connecting to the target system consists of the following steps:
• Turn off the logic analyzer and the target system.
• Connect the preprocessor interface to the target system.
The remainder of this section describes these general steps in more
detail.
To powerup or power down
To protect your equipment, remove the powerfrom both the logic analyzer
and the target systembefore you make or break connections. The logic
analyzer provides power to the circuits on the preprocessorinterface, and
should always be powered up before the target system. When powering
down, power down the target systemfirst and then power down the logic
analyzer.

CAUTION
Connecting to the Target System
To connect the preprocessor to the target system
To connect the preprocessor to the target system
The microprocessor connector on the preprocessorinterface will connect
directly to the PGA socket on the target system. The PowerPC 604
microprocessor connects to a pin protector on top of the preprocessor
interface.
1 To prevent equipmentdamage, remove power from both the logic
analyzer and the target system.
2 Remove the 604 PGA microprocessor from its socket on the target
system and store it in a protected environment.
3 Install the preprocessor interface into the PGA socket on the target
system. Ensure that pin Al is properly aligned (see figure on next
page). The socket on the preprocessor interface is designedwith
low-insertion-force pins to allow insertion and removal with
minimumforce.
Serious damage to the target system or preprocessorinterface can result
from incorrect connection. Note the position of pin Al on the targetsystem,
preprocessorinterface, and microprocessor prior to making any connection.
Also, take care to align the preprocessor interface connectorpinswith the
________ targetsystem PGAsocket so that all pins aremaking contact.
If the preprocessor interface connector interferes with components of the
target system or ifa higher profile is required, additional plastic pin protector
sockets can be added. Plastic pin protector sockets can be ordered from
Hewlett-Packard using the part number 1200-1975. However, any 287-pin PGA
IC socketwith a604footprint and gold-plated pins can be used.
4 Plug the PowerPC 604 microprocessor into a pin protector, and plug
that into the PGA socket on the preprocessor interface, again
ensuring that pin Al is properly aligned.
The PowerPC 604 microprocessor can be difficult to remove if you connect it
directlyto the preprocessor interface. Always use a pin protector between the
microprocessor and the PGA socket on the preprocessor interface.
