Design a One-Bit ALU with 4 Functions There are two design methodologies. In the lecture, we have discussed one-bit ALU design using "enablers," which are a set of AND gates controlling what output will be taken. It is straightforward but sometimes may require more hardware resource than the other method, which is the basic combinational logic design approach. In this lah, you will use the latter design methodology. You first figure out what the truth table is for the ALU based on the functionality described in the prior knowledge section. From the derived truth table, you will find a Boolean equation that describes the logic using the Karnaugh map. You will then draw a schematic diagram for your design. At last, you will implement your design on XK-550 digital trainer. 1. Figure out the truth table. The ALU does not have inputs A and B only. It includes C1 and CO control inputs as well. Therefore, there are 4 inputs, and one output. Fill in the truth table below. 0 0 Instructor check 0 0 0 -o o-o 0 1 - -o 1 1 1 1 0 0 0 0 0 0 1 1 Copyright 2014-2020 by Chia Tien Dan Lo Design a One-Bit ALU with 4 Functions There are two design methodologies.
