The
bound
bit
is
interpreted
as
follows:
o -
this
process
is
bound
to
a processor
1 -
this
process
is
not
bound
to
a
processor
The

are
as

The

are
the
same
for
IPs
as
they
are
for
GDPs.
Fault
information
for
context,
process,
and processor
level
faults
has
the
same
organization.
Process
objects
contain
fault
information
for
context
and
process
level
faults.
Processor
objects
contain
fault
information
for
processor
level
faults.
Access
to
the
context
fault
information
is
made
available
to
a
context
via
the
software convention
of
providing a refinement
for
it
in
a
known
entry
of
the
process
global
access
segment.
The
process
fault
information
area
in
the
process
object
is
used
when
a
process-level
fault
occurs and a
process
is
bound
to
the
processor.
The
processor
fault
information
area
in
the
processor
object
is
used
when
a
process
level
fault
occurs and a
process
is
not
bound
to
the
processor.
The
organization
of
the
fault
information
area
is
described
in
Appendix C,
the
Fault
Summary.
The
base
rights
field
of
a

segment access
descriptor
is
interpreted
in
the
same
manner
as
for
all
objects
of
base type
data
segment.
The
system
rights
field
of
a process
data
segment
access
descriptor
is
uninterpreted.
