21 VHDL Design of Combinational Arithmetic Circuits
Chapter Contents
21.1 Carry-Ripple Adder
21.3 Signed and Unsigned Adders/Subtracters
21.4 Signed and Unsigned Multipliers/Dividers
21.5 ALU
21.6 Exercises
Objective:
Chapter 20 showed VHDL designs for combinational logic circuits. The second and final part of combinational circuits is presented in this chapter, which exhibits VHDL designs for combinational arithmetic circuits (studied in Chapter 12).
21.1 Carry-Ripple Adder
In this section and in the next, the physical structures of adders/subtracters are explored, while in Section 21.3 the types of addition/subtraction (that is, unsigned or signed) are considered.
Adders are combinational arithmetic circuits, ...
