SPEED
.
PIPELINE
Integer
No
Specifies the number of clock cycles needed to produce
the result. For the single-precision format, the latency
options are
33
,
14
or
6
. For the double-precision
format, the latency options are
61
,
24
or
10
.
For the single-extended precision format, the value
ranges from a minimum of
41
to a maximum of
61
.
For the low-latency option, the latency is determined
from the mantissa width. For a mantissa width of
31
to
40
bits, the value is
8
or
18
. For a mantissa width of
41
bits or more, the value is
