Design the 32-bit alu shown in figure 515 using your

Question

Add an Overflow output to the 32-bit ALU from Exercise 5.9. The output is TRUE when the result of the adder overflows. Otherwise, it is FALSE.

(a) Write a Boolean equation for the Overflow output.

(b) Sketch the Overflow circuit.

(c) Design the modified ALU in an HDL.

Exercise 5.9:

Design the 32-bit ALU shown in Figure 5.15 using your favorite HDL. You can make the top-level module either behavioral or structural.
