February 2011 Altera Corporation
To implement this complex multiplication within the DSP block, the real part
((a × c) – (b × d)) is implemented using two multipliers feeding one subtractor block
while the imaginary part ((a × d) + (b × c)) is implemented using another two
multipliers feeding an adder block.
multiplication. This mode automatically assumes all inputs are using signed
numbers.
