Performance
Analysis
Measurements
As
the
software
begins
to
push
the
limits
of
the
hardware
of
a
system,
the
need
for
more
efficient
code
becomes
much
more
apparent
.
The
software
must
be
able
to
respond
to
all
of
its
inputs
in
a
timely
fashion,
with
little
or
no
delays
.
Performance
Analysis
allows
the
programmer
to
analyze
code-to
find
bottlenecks
and
inefficiencies
.
The
Overview
Measurements
of
the
1630
series
logic
analyzers
(available
in
the
state-only
configuration)
provide
the
programmer
with
tools
with
which
to
perform
this
analysis
.
These
tools
allow
the
programmer
to
analyze
module
processor
usage,
intermodule
linkage,
module
duration,
and
time-based
interaction
.
The
output
of
these
tools
appear
as
bar
graphs
(called
histograms)
relating
the
relative
actions
between
measured
items
.
These
histograms
are
presented
in
the
chart
menu
after
the
trace
specification
has
been
set
up
for
an
overview
measurement
.
With
the
exception
of
the
Time
Positional
measurement,
these
measurements
execute
in
a
continuous
random
sample
mode
.
A
sample
consists
of
1024
qualified
states
.
The
time
between
states
varies
randomly
to
insure
random
sampling
.
To
stop
a
measurement
immediately,
press
the
STOP
key
twice
.
The
first
press
will
force
the
analyzer
to
take
one
more
sample
and
then
quit
.
Two
consecutive
STOPs
will
force
the
analyzer
to
abort
the
current
sample
.
The
following
chapter
describes
the
overview
measurements,
and
provides
example
usages
of
these
measurements
.
The
1630A/D
analyzers
can
show
two
types
of
histograms
:
state
label
histograms
and
time
interval
histograms
.
The
1630G
analyzer
can
show
two
types
of
state
label
histograms
(counting
states
or
program
activity),
time
interval
histograms,
time
position
histograms
and
linkage
histograms
.
STATE
LABEL
OVERVIEW
MEASUREMENT
State
Label
Overview
Measurement
allows
the
programmer
to
define
module
code
ranges
and
then
compute
the
amount
of
time
spent
within
these
modules,
relative
to
each
other,
or
relative
to
the
entire
system
software
.
The
ranges
are
defined
for
one
of
the
eight
possible
labels
defined
in
the
format
menu
.
(For
a
typical
inverse
assembler
application,
these
would
be
ADDR,
DATA,
and
STAT
.)
The
ranges
may
be
defined
as
any
locations
between
the
maximum
and
minimum
values
possible
for
that
label
.
State
Label
Measurement
is
very
beneficial
in
improving
overall
system
performance
.
It
allows
the
programmer
to
define
sections
of
code
critical
to
the
overall
system
or
module
performance,
and
thereby
avoid
wasting
time
attempting
to
optimize
code
that
does
not
noticeably
affect
overall
performance
.
For
example,
a
module
that
performs
floating
point
processing
is
found
to
be
noticeably
slow
.
The
floating
point
module
consists
of
seven
routines
:
F_ADD,
F_SUB,
F_MUL,
F_DIV,
F_CMP,
F_MOVE,
and
F_NORM
.
These
routines
provide
floating
point
addition,
subtraction,
multiplication,
division,
comparison,
moves,
and
normalization
.
To
improve
the
module
performance,
the
individual
routines
are
defined
in
the
State
Label
Trace
menu,
and
then
analyzed,
as
in
the
following
steps
.
