Chapter 10, Problem 10.22(choose chapter or problem)
Write VHDL code that gives a behavioral description of a circuit that converts the representation of decimal digits in the weighted code with weights 8, 4, −2 and −1 to the representation using the excess-3 code.
(a) Write the code using the when else assignment statement.
(b) Use the VHDL simulator to verify the code of part (a) for the inputs x = 0011, 0100, 1001, and 1010.
(c) Write the code using the with select when assignment statement.
(d) Use the VHDL simulator to verify the code of part (c) for the inputs x = 0100, 0101, 1001, and 1010.
