S = (X x Y) + K + M Where: x means Arithmetic Times.

S = (X x Y) + K + M Where: + means Arithmetic Plus.

S = S(m + n–1) S(m + n–2) … S2 S1 S0

X = X(m–1) X (m–2) … X2 X1 X0, Y = Y(n–1) Y(n–2) … Y2 Y1 Y0

K = K(m–1) K(m–2) … K2 K1 K0 and M = M(n–1) M(n–2) … M2 M1 M0

(Binary Numbers).

Number of output binary digits = m + n

Number of packages = mxn/4 (For m or n of both odd select next highest even number.)
