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.
