I wrote an inline complex multiplier based around a single DSP which
really gets into the guts of the DSP core. It's hard to see how one
would do this in plain VHDL with a hope that it would be inferred
correctly (the difficulty is in things like flicking control registers
mid pipeline from multiply-add to multiply-accumulate to
multiply-deccumulate).
