The MC14554B 2 x 2?bit parallel binary multiplier is constructed with
complementary MOS (CMOS) enhancement mode devices. The multiplier
can perform the multiplication of two binary numbers and simultaneously add
two other binary numbers to the product. The MC14554B has two
multiplicand inputs (X0 and X1), two multiplier inputs (Y0 and Y1), five
cascading or adding inputs (K0, K1, M0, M1, and M2), and five sum and
carry outputs (S0, S1, S2, C1 [S3], and C0). The basic multiplier can be
expanded into a straightforward m?bit by n?bit parallel multiplier without
additional logic elements.
Application areas include arithmetic processing (multiplying/adding,
obtaining square roots, polynomial evaluation, obtaining reciprocals, and
dividing), Fast Fourier Transform processing, digital filtering, communications (convolution and correlation), and process and machine controls.
