Twenty years ago, a famous logic designer decided to quit teaching and make a fortune by licensing the circuit design shown in Figure.

(a) Label the inputs and outputs of the circuit with appropriate signal names, including active-level indications.

---

(b) What does the circuit do? Be specific and account for all inputs and outputs.

---

(c) Draw the logic symbol that would go on the data sheet of this circuit.

---

(d) Write an ABEL or behavioral VHDL or Verilog program for the circuit.

---

(e) With what standard building blocks did the new circuit compete? Do you think that it was successful as an MSI part?
