ALTFP_SINCOS Parameters
Table 14-4: ALTFP_SINCOS IP Core Parameters
Parameter Name Type Required Description
WIDTH_EXP Integer Yes Specifies the precision of the exponent. The bias of
the exponent is always set to
2 (WIDTH_EXP-1) -1
(that
is,
127
for single-precision format). The value of
WIDTH_EXP
must be
8
for single-precision format
and must be less than
WIDTH_MAN
. The available
value for
WIDTH_EXP
is
8
.
WIDTH_MAN Integer Yes Specifies the precision of the mantissa. The value of
WIDTH_MAN
must be
23
when
WIDTH_EXP
is
8
.
Otherwise,
WIDTH_MAN
must be a minimum of
31
.
The value of
WIDTH_MAN
must be greater than
WIDTH_EXP
. The available value for
WIDTH_MAN
is
23
.
PIPELINE Integer Yes The number of pipeline is fixed for the mantissa
width and some internal parameter. For the correct
settings, refer to Output Latency.
