Abstract
PURPOSE: To give the flexibility to the system design by realizing such multiplier that comprises N-units of multipliers and can be used as one unit of the multiplier as a whole or as several units of multipliers according to the coefficient word length.
CONSTITUTION: N-unit multiplicand X and multiplier A are multiplied each other in N-unit multipliers to obtain N-unit output Y, and at the same time the output of the multiplier has the digit shift with an addition possible with the output having no digit shift. Thus a larger digit number can be applied for the multiplier. Furthermore, an addition is given with the output of other multipliers or adders by giving the digit shift to the addition output, and thus the digit number can be increased more for the multiplier. In that case, the same multiplier is given to the multipliers which perform multiplication simultaneously. Several multipliers are combined according to the digit number of the multiplier to obtain the output, and then several multiplications become possible at one time with combinations of multipliers.
