Design a 2-bit alu that performs the following four operations: (However, the internal circuit of the full adder may be omitted)
s0 s1 operation comment
0 0 clear F=00
0 1 A plus B F=A+B
1 0 A minus B F=A-B
1 1 A exclusive-or B F=A exclusive-or B
Homework Answers
->as shown in figure that if s0=0 and s1=0 then simply zero will be F
->if s0=0 and s1=1 then we have to perform A+B so that we have two Full Adder(FA) which will perform A+B and output of both FA are f0 and f1 and it is our F.
->if s0=1 and s1=0 then we have to perform A-B so that we have two Full Adder(FA) which will perform A-B and output of both FA are f0 and f1 and it is our F.
->if s0=1 and s1=1 then we have to perform A-ex-OR-B so that we have two Full Adder(FA) which will perform A-ex-OR-B and output of both FA are f0 and f1 and it is our F.

Design a 4-bit Arithmetic Logic Unit (ALU) according to the following specification
Design a 4-bit Arithmetic Logic Unit (ALU) according to the following specification. Follow the design shown during the lecture. Notice this table is different, though. 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) b. Create a symbol for your logic unit and use four of them to make a 4-bit logic unit c....

PROBLEM STATEMENT The mini-calculator will use a small ALU to perform arithmetic operations on two 4-bit values which are set using switches. The ALU operations described below are implemented with an Adder/Subtractor component. A pushbutton input allows the current arithmetic result to be saved. An upgraded mini-calculator allows the saved value to be used in place of B as one of the operands. The small ALU that you will design will use the 4-bit adder myadder4 to do several possible...

An Arithmetic and Logic Unit (ALU) is a combinational circuit
that performs logic and arithmetic micro-operations on a pair of
4-bit operands. The operations performed by an ALU are controlled
by a set of function-select inputs. In this lab you will
design a 4-bit ALU with 3 function-select inputs: Mode M, Select S1
and S0 inputs. The mode input M selects between a Logic (M=0) and
Arithmetic (M=1)...
