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...
This section gives you freedom to come up with your own solutions. 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)...

9) (2 points) You are given two, 3-bit, two's complement integers A[2:0, B(2 : 0). You are asked to design a two's complement (signed) comparator circuit that produces f = 1 when A > B; otherwise f = 0. Design the above circuit (block diagram) assuming that you are given: i) pre-designed 3-bit unsigned comparators (f = A > B), ii) MUXes, and iii) any AND/OR/XOR/NOT Boolean logic gates.
