ABSTRACT:
A low power tap multiplier multiplies a m-bit multiplier and a n-bit multiplicand to output a p-bit multiplication product. The p-bit product is one bit more than the n-bit multiplicand when the multiplicand is symmetric, and two bits more when the multiplicand is non-symmetric. Since the low power tap multiplier utilizes a minimal number of small unstacked transistors, it consumes less power and requires less silicon area.
