Array multiplier is very popular for multiplication of binary numbers. Array multiplier resembles the pen and paper method of multiplication process. Array multiplication process for two 4-bit unsigned numbers *a* and *b* is shown below.

On the contrary to the sequential multiplier, array multiplier is parallel. A array of full adders are used for the multiplication process. For n-bit data width, total n(n-1) full adders are used in this multiplier. Carry outputs of a stage is added in the next stage to form a systolic architecture. But in the last stage carry is used in the same stage to reduce hardware. The architecture of the array multiplier is shown below.
