ES 112 Project 2 bit ALU

2
Design a 2-bit ALU Design a 2-bit ALU capable of performing the following operations: – ADD – Multiplication – Bitwise AND – Bitwise OR

3
Description of ADD operation Assume that the bits are unsigned Inputs (A1, A0) and (B1, B0) Implement the 2 bit adder in a “flat schematic”, i.e. draw all your gates in the same schematic. Do not use subcircuits for this exercise.

4
Description of a Multiply Operation Inputs (A1, A0) and (B1, B0) Implement the 2 bit multiplier in a “flat schematic

5
Definition of the 4-1 MUX S1S0Operation 00Multiplication 01Add 10Bitwise AND 11Bitwise OR

6
Multiply S1S0A1A0B1B0D3D2D1D

7
Add Operation S1S0A1A0B1B0D3D2D1D

8
AND Operation S1S0A1A0B1B0D3D2D1D

9
OR Operation S1S0A1A0B1B0D3D2D1D
