8.10 VHDL DESCRIPTION OF ARITHMETIC DEVICES 383
description of a four-bit adder composed of four full adders described in the previous
example. If Fig. 8.49 is used with reference to Figs. 8.4 and 8.5, the structure of the four-bit
adder is given as follows:
entity four
bit adder is
port (a0, a1, a2, a3, b0, b1, b2, b3, ci: in bit; s0, s1, s2, s3, co: out bit;
end four
