About this Manual

We’ve added this manual to the Agilent website in an effort to help you support

your product. This manual is the best copy we could find; it may be incomplete

or contain dated information. If we find a more recent copy in the future, we will

add it to the Agilent website.

Support for Your Product

Agilent no longer sells or supports this product. Our service centers may be able

to perform calibration if no repair parts are needed, but no other support from

Agilent is available. You will find any other available product information on the

Agilent Test & Measurement website, www.tm.agilent.com.

HP References in this Manual

This manual may contain references to HP or Hewlett-Packard. Please note that

Hewlett-Packard's former test and measurement, semiconductor products and

chemical analysis businesses are now part of Agilent Technologies. We have

made no changes to this manual copy. In other documentation, to reduce

potential confusion, the only change to product numbers and names has been in

the company name prefix: where a product number/name was HP XXXX the

current name/number is now Agilent XXXX. For example, model number

HP8648A is now model number Agilent 8648A.

HP E2466C Preprocessor

Interface for the Intel

Pentium® II Processor

The HP E2466C Preprocessor

Interface—At a Glance

The HP E2466C Preprocessor Interface, when used together with the

HP 16505A Prototype Analyzer, provides a complete interface for state or

timing analysis between any Intel Pentium® II processor target system and

the HP logic analyzers listed below. The HP E2466C Preprocessor Interface

requires that the logic analyzer module is in an HP 16500B/C mainframe; the

HP 16505A Prototype Analyzer is also required.

The inverse assembler provides Pentium II processor assembly language

mnemonics and accurate instruction execution tracking of up to four

processors. The inverse assembler also supports Intel’s MMXTechnology.

The HP E2467A APIC Bus Preprocessor Interface can also be used with the

HP E2466C Preprocessor Interface to provide simultaneous bus analysis.

For instruction disassembly, Branch Trace Messagesmustbe enabledand

cachesmust bedisabled. Thisrequiresa Pentium IIprocessor run-control tool

(suchas theHP E3493A) anda 30-pin debug porton the target system.

ii Preprocessor Interface for the Pentium II Processor

The HP E2466C Preprocessor Interface consists of the configuration

software, for configuring the logic analyzer and the HP 16505A Prototype

Analyzer, and the preprocessor interface hardware, which connects to the

target system and processes the signals.

For more information on the supported logic analyzers, the HP 16505A, or

the microprocessor, refer to the appropriate reference manuals for those

products.

In This Book

This book is the user’s guide for the HP E2466C 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 and one appendix:

Chapter 1 explains how to set up and configure the preprocessor

interface and logic analyzer for state or timing analysis.

Chapter 2 provides reference information on the logic analyzer format

specification and symbols configured by the preprocessor interface

software, and information about the transaction tracker files. It also

contains information about the inverse assembler.

Chapter 3 contains reference information on the preprocessor

interface hardware, including the characteristics and signal mapping

for the preprocessor interface.

Appendix A contains information on troubleshooting problems or

difficulties which may occur with the preprocessor interface.

For more information on the logic analyzers or microprocessor, refer to the

appropriate reference manual for those products.
