Design a 4-bit Arithmetic Logic Unit S2 0 0 Table 1: Function table for arithmetic-logic unit. SELECTION INSTRUCTONS S1 SO 0 0 Addition Increment A 0 Decrement A 1 Subtraction (2's complement) 0 | 0 NAND 0 NOT 1 0 NOR 1 1 XOR 0 1 1 1 1. Determining the carry propagation/suppression logic. Show all of your work including truth table and final logic equation. 2. Next, create the same type of truth table illustrated in class, showing SO SI, Yi, Xi, Current Output, and Desired Output (Zi). 3. Using the information in the previous table, determine the value of Xi for each of the logical instructions. Show the truth tables, where necessary.
