One way to increase the speed of operation of a given circuit is to insert registers into the circuit in a way that shortens the lengths of its longest paths. This technique is referred to as pipelining a circuit, and the inserted registers are often called pipeline registers. Insert pipeline registers into your design between the multipliers and the adder. Recompile your project and discuss the results obtained. Part IX The Quartus II software includes a predesigned module called altmult add that can perform calculations of the form S = (A × B)+(C × D). Repeat Part VIII using this module instead of the lpm mult and lpm add sub modules. Test your circuit using both simulation and by downloading the circuit onto the DE2 board. Briefly describe how the implementation of your circuit differs when using the altmult add module. Examine its performance both with and without the pipeline registers discussed in Part VIII.
