  6. You can find a generic implementation of a wallace tree multiplier here: http://www.openhdl.com/vhdl/655-vhdl-component-wallace-tree-multiplier-generic.html

    This implementation uses a small set of recursive functions to identify the number of applicable bits at a given layer. The main code then maximizes the number of 3:2 compressors (full adders) followed by 2:2 compressors (half adders) and then wires.

    The final partial sums are fed into a generic Brent-Kung adder (a type of carry tree adder like other carry look-ahead adders including the Kogge-Stone adder).

    Hope that helps!
