Design a 4-bit Arithmetic Logic Unit (ALU) according to the following specification. Follow the design shown during the lecture. Notice that the order of operations is different here. A (0:3) S₂. So ALU B (0:3) F (0:3) Z, C and V are status flags Z = 1 if F = 0 V = Overflow C = Carry or Borrow Z V C S₂ 0 0 0 0 1 1 1 1 S₁ 0 0 1 1 0 0 1 1 So 0 1 0 1 0 1 0 1 Function (F) A+B A-B A-1 A +1 A AND B A OR B NOTA A XOR B Figure 1 Design specifications. a. Create the internal of 1-bit of the logic unit (It is recommended that you design the internal of a 4 to 1 MUX first, create a symbol for it and use it for creating the logic unit, you find the design in your MUX lecture slides) b. Create a symbol for your logic unit and use four of them to make a 4-bit logic unit c. Create the internal of 1-bit of the Arithmetic unit (It is recommended that you design the internal of a Full Adder first, create a symbol for it and use it for creating the arithmetic unit) d. Create a symbol for your arithmetic unit and use four of them to make a 4-bit arithmetic unit e. Create a 4-bit, 2-1 multiplexer (use buses). f. Create a schematic diagram for the complete 4-bit ALU g. Create a test situation for your ALU by defining A as 0001 and B as 0001. You can used GND and VCC for constant 0 and constant 1. h. Demonstrate your design using the FPGA board. Use switches for select functions. Use LEDs to show results and flags.
