UG-01063
The ALTMULT_COMPLEX megafunction implements the multiplication of two complex numbers and
offers the conventional implementation mode.
You can use the conventional representation for the following:
• All supported Altera devices
• Input data widths of any size
The ALTMULT_COMPLEX megafunction implements the multiplication of two complex numbers and
offers the following two implementation modes:
• Canonical
You can use the canonical representation for the following:
• All supported Altera devices prior to Stratix III devices. The canonical representation is no longer
supported from Stratix III onwards
• Input data widths of less than 18 bits
• Conventional
You can use the conventional representation for the following:
• All supported Altera devices
• Input data widths of any size
With the conventional representation, you can use the ALTMULT_ADD megafunction to implement the
complex multiplier by instantiating two multipliers.
The following figure shows the ports for the ALTMULT_COMPLEX megafunction.
