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)...
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....

Using Structural Modeling in VHDL write the
code for:
An Arithmetic Logic Unit (ALU) shown in the
figure below. A (16-bit), B
(16-bit), Opcode (3-bit), and
Mode (1-bit) are the inputs; and
ALUOut (16-bit) and Cout (1-bit) are the outputs
of the design. A and B hold the values of the operands. Mode and
Opcode together indicate the type of the operation performed by
ALU.
The ALU components ARE:
-Arithmetic Unit that consists of one 16-bit
adder, 16-bit subtractor, 16-bit...

Implement an arithmetic logic unit (ALU) using Verilog. Consider signed number arithmetic operation. The outputs of the ALU should be 1) Addition of two 8-bit numbers 2) A Zero Flag. It is set (it is 1 if the condition is met and 0 otherwise) if the result is zero. 3) A Negative Flag. It is set (it is 1 if the condition is met and 0 otherwise) if the result is less than 0. 4) An Overflow Flag. It is...
