Introduction
Logic
Analyzers
Supported
The HP E2418A Preprocessor Interface provides a complete interface
for monitoring external bus operations of a TMS32020/C25 target
system with the following logic analyzers: HP 1650A, HP 1650B,
HP 1652B, HP 1660A/6W62A, HP 16510A, HP 16510B, HP 16511B,
HP 16540/16541A,D, HP 16542A, or HP 16550A.
Since the HP E2418A only monitors external bus operations of the
TMS32020/C25, the TMS32020/C25 must be operated in the
"microprocessor" mode (versus the "microcomputer" mode). In
microprocessor mode, the bus operations to the external program
memory are available to be capturedby the logic analyzer. Accesses to
TMS32020/C25 internal resources are not presented on the external
data bus.
The TMS32020/C25 configuration software on the flexible disk sets up
the format specification menu of the logic analyzer for compatibility
with the TMS32020/C25 microprocessor. It also loads the inverse
assembler for obtaining displays of TMS32020/C25 data in
TMS32020/C25 assembly language mnemonics.
The following logic analyzers are supportedby the HP E2418A
Preprocessor Interface:
HP 1650A, HP 16508, HP 16528, HP 16510A, and HP 165108
These logic analyzers provide 1 k of memory depth with either 80
channels of 35 MHz state analysis (25 MHz state analysis for the
HP 1650A or HP 16510A) or 80 channels of 100 MHz timing
analysis.
HP 1660A/61A/62A
The HP 1660A/6W62A Logic Analyzers provide 4 k of memory
depth with 136 channels (HP 1660A), 102 channels (HP 1661A),
or 68 channels (HP 1662A) of 100 MHz state analysis or 250 MHz
timing analysis. These logic analyzers also support various
combinations of mixed state/timing analysis.

Master Disk
HP E2418A
This chapter explains how to install and configure the HP E2418A
Preprocessor Interface for state analysis of external bus operations
with the supportedlogic analyzers.
Before you use the HP E2418A software, use the Duplicate Disk
operationin the disk menu of your logic analyzer to make a duplicate
copy of the HP E2418A master disk. Store the master disk and use the
back-up copy to configure your logic analyzer. This will help prevent
the possibility of losing or destroying the originalfiles in the event the
disk wears out, is damaged, or a file is accidentally deleted.

Caution f,
HP E2418A
The following procedure describes the major steps required to perform
measurements with the HP E2418A Preprocessor Interface. The page
numbers listed in the various steps refer you to sections in this manual
that offer more detailed information.
To prevent equipment damage, be sure to remove power from both the
logic analyzer and the target system whenever the preprocessor
interface or microprocessor is being connected or disconnected.
1. Ensure that the TMS32020/C25 is operating in microprocessor
mode. In microprocessor mode, the bus operations to the
external program memory are available to be capturedby the
logic analyzer. Accesses to TMS32020/C25 internal resources are
not presented on the external data bus.
2. If they are not already connected, connect the 100 kOhm
Termination Adapters to the connectors on the preprocessor
interface (see page 1-4).
3. Install the preprocessor interface in the target system
(see page 1-5).
4. Connect the logic analyzer probes to the termination adapters on
the connectors on the preprocessor interface board as listed in
table 1-1 (see page 1-8).
5. Power up the logic analyzer, and then the target system. Since
the logic analyzer provides power to the preprocessor interface, it
must always be powered up first.
6. Load the logic analyzer configuration file for the specified logic
analyzer (see page 1-11). Table 1-1 lists the configuration files.

The following steps explain how to connect the HP E2418A
Preprocessor Interface to your target system:
To prevent equipment damage, be sure to remove power from both the
logic analyzer and the target system whenever the preprocessor
interface or microprocessor is being connected or disconnected.
1. Remove the TMS32020/C25 microprocessor from its socket on
the target system and store it in a protected environment.
Serious damage to the target system or preprocessor interface can
result from incorrect connection. Note the position of pin Al (figure
1-2) on the preprocessor interface connector and the target system
socket prior to inserting the connector in the socket. Also, take care to
align the preprocessor interface connectorwith the socket on the target
system so that all microprocessor pins are making contact.
2. Plug the preprocessor interface connector into the
microprocessor socket on the target system.
If the preprocessor interface connector interferes with components of
the target system or if a higher profile is required, additional plastic pin
guards can be added. Plastic pin guards can be ordered from
Hewlett-Packard using the part number 1200-1458. However, any
68-pin PGA IC socket with a TMS32020/C25 foot print and gold-plated
pins can be used.
3. Plug the TMS32020/C25 microprocessor into the socket of the
preprocessor interface board. The socket on the preprocessor
interface board is designed with low insertion force pins to allow
you to install or remove the microprocessor with a minimum
amount offorce.

Note 0
Care must be used when removing a microprocessor or socket from the
preprocessor interface board to prevent damaging the traces on the
board.
4. Power up the logic analyzer, and then the target system.
Protect your equipment. Since the logic analyzer provides power to the
preprocessor interface, the logic analyzer should always be powered up
whenever the target system is powered up or down.

preprocessor interface, while Pod 1 refers to a logic analyzer pod.
Figure 1-3 shows the relative locations of the logic analyzer cards.
HP 16542Awith three or four Expansion Cards
The locations for the HP 16542A expansion cards, relative to the
Master Card, depend on the number of expansion cards used. If one
or two expansion cards are used, Card 1 is located above the Master
Card and Card 2 is located below the Master Card. If three expansion
cards are used, two of them are located above the Master Card and the
third is located below the Master Card. When four expansion cards
are used, they are located as shown in figure 1-3.
Table 1-1 shows the physical locations and connections for a
two-expansion-card system. If you are using more than two expansion
cards, check the Format menu in the logic analyzer to see where the
pods should be connected.
When powering up, the logic analyzer must be powered up first, and
then the target system. The logic analyzer provides the power to the
active circuits on the preprocessor interface; unpowered circuits may
cause improper operation of the target system.
When powering down, the target system should be powered down first,
and then the logic analyzer.
