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)...

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...
