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...

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...

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)...
