        README file for acecpu32 back end example

This directory contains the files for the acecpu32
back end example.  This fictitious example provides
back end support for the ACE Super BDM emulator,
which supports debugging via background debug
mode on Motorola CPU32 microprocessors.  This
example assumes that ACE already had a C API 
to operate their emulator.  Consequently, the
back end only needed to integrate the C API into
a Tornado-style back end.

The acecpu32 back end uses the back end framework
and facilities provided by the Back End Developer's
Kit (BEDK) class library, which is located in
${WIND_BASE}/host/src/tgtsvr/backend/bedk.  To understand
how to write a Tornado back end, you should first
consult the chapter "Target Server Back End" in the 
_Tornado API Guide_, and then examine the code provided 
in the BEDK class library.  Finally, examine the example 
in this directory.

The files for the acecpue32 example are:

    * README              - this file.

    * Makefile            - a sample Makefile for SunOS 4.1.3.

    * acecpu32.mak        - a sample makefile for Microsoft Visual C++ 2.1
                            (Windows NT and '95) (obsolete).

    * acecpu32_4.mak      - a sample makefile for Microsoft Visual C++ 4.2

    * acecpu32.def        - a sample exports file for back end DLL
                            built with MSVC (Windows host).

    * acecpu32-d.def      - a sample exports file debug verion of back end
                            DLL build with MSVC (Windows host).

    * acecpu32.cpp        - the "entry-point" of the acecpu32 back end.

    * acecpu32Backend.h   - declares structure of Ace_T back end class.
    * acecpu32Backend.cpp - implements Ace_T back end class.

    * event.h             - declares Event_T class for managing event 
                            information.
    * event.cpp           - implements Event_T.

    * bdmExcLib.h         - declares information used for host/target 
                            event notification.
