Description of the data path
Description
of
the
data
path
Camera
timing
is
described
in
the
following
table.
Standard Update (IIDC)
In
the
Standard
Update
(IIDC)
mode
single
parameter
are
sent
to
the
camera.
•
Standard
Update
(IIDC)shows
same
behavior
as
Marlin
•
Parameter
will
be
sent
from
host
to
camera
and
will
be
activated
as
soon
as
possible
without
interruption
of
the
transfer
•
If
the
host
updates
more
than
one
parameter
(without
block
write)
the
parameters
may
become
active
in
different
images
•
Standard
Update
(IIDC)
can
be
combined
with
the
new
parameter
update
timing
modes
Camera
timing
behavior
is
described
in
the
following
table.
Fast Parameter Update Timing
Quick Format Change Mode
(QFCM)
After
block
write
command
is
processed
in
the
camera
all
changed
parameters
are
valid
for
the
available
next
image.
Frame
rate
is
constant.
After
transfer
of
the
parameter
list
via
block
write
a
current
transfer
will
be
finished.
A
started
exposure
will
be
interrupted
until
the
microcontroller
has
processed
the
list
and
copied
it
into
the
FPGA.
Exposure
of
the
next
image
with
new
parameters
is
started.
There
may
be
a
gap
between
two
images.

Fast Parameter Update Timing
Quick Format Change Mode
(QFCM)
After
sending
a
new
parameter
value,
the
changed
parameter
value
is
valid
for
the
available
next
image.
Frame
rate
is
constant.
After
sending
a
new
parameter
value,
the
changed
parameter
value
is
valid
for
the
available
next
image.
A
running
exposure
will
be
interrupted
and
the
image
is
dropped.
There
may
be
a
gap
between
two
consecutive
image
transfers.
