1. Given F = A'B' + BC' and G = AC + B', write a complete VHDL module that realizes the functions F and G using an 8-word × 2-bit ROM. Include the array type declaration and the constant declaration that defines the contents of the ROM.

2. Implement the following state table using a ROM and two D flip-flops. Use a straight binary state assignment.

(a) Show the block diagram and the ROM truth table. Truth table column headings should be in the order Q₁ Q₀ X D₁ D₀ Z.

(b) Write VHDL code for the implementation. Use an array to represent the ROM table, and use two processes.
