Unsigned wallace multiplier represents fast N-bit multiplier which utilizes
|
||
the functionality of wallace tree reduction algorithm proposed by Chris Wallace.
|
||
|
||
First partial products are calculated for each bit pair that form the partial product multiplication columns.
|
||
At last the reduced pairs are inserted into chosen multi bit unsigned adder to execute their summation and obtain the final output bits.
|
||
|
||
Wallace tree algorithm is described more in detail here:

|

It presents smaller circuit in area opposed to array multiplier but is slightly bigger then dadda because of less reduction stages.
