PREFACE
Understanding
any complex comp.lting
system,
such
as
the
Intel
iAPX
432,
requires
the
assimilation
of
a
great
deal
of
technical
information.
Before
reading
this
manual on
the
architecture
of
the
432
Interface
Processor,
the
reader
should
have conmand
of
the
general
432
concepts.
Intel
offers
three
documents which
provide
these
prerequisites.
o The
INTEL
432 System Summary, Order
Number
171867,
provides
the
broad
picture
of
the
432.
It
should
be
read
as
a
first
introduction
to
the
432
system.
o The
Introduction
to
the
iAPX
432
Architecture,
Order
Number
171821,
restricts
discussion
to
general
architecture
features
which
distinguish
the
432.
o The
iAPX
432
General
Data
Processor
Archi
tecure
Reference
Manual,
Order
Number
171860-001,
provides
detailed
information
on
one
type
of
432
processor,
a
General
Data
Processor
(GOP).
Its
glossary
is
a
concise
surrmary
of
the
rrost
important
terminology
which
is
required
when
reading
the
Interface
Processor
manual.
This
manual
describes
another
432
processor,
the
Interface
Processor
(IP),
similar
in
many
respects
to
a
GOP
and
different
in
others.
Rather
than
duplicate
all
of
the
general
432
information
oontained
in
the
companion documents,
this
manual
relies
00
the
above
references
for
descr
iptions
of
features
of
432
archi
tecture
which
are
common
among
processors.
Unique
features
am
functions
of
the
IP
are
presented
and
oontrasted
with
those
of
the
GOP
when
appropriate.
Chapters
1
through
6
of
this
manual
are
oomposedof
descriptions
of
the
Interface
Processor,
allowing
the
reader
to
understand
the
cx:x>peration between an
IP
and
Peripheral
Subsystems
in
forming a
logical
I/O
processor
for
a 432
system.
Detailed
representations
for
the
objects,
descriptions
of
windCMs
and
functions,
faults,
interrupts,
am
initialization
may
be
foum
in
the
apperrlices.
