Show an image of the completed 8 BIT ALU The most important and possible most difficult component to implement is the arithmetic logic unit. The
functions of the ALU are shown in Table 1. The ALU should have 5 inputs (A-input, B-input, F0-input, F1-input, Finput) and 1 output (C-output). You will need to determine how many bits each input and output should have.
Remember, you are designing an 8-bit microprocessor! To achieve the specified ALU functions, think about
which digital logic component(s) you can use to accomplish the task. For example, to add the value on the A-bus
8-bit ALU

to the value on the B-bus, you can simply use an 8-bit adder. Explore the components in Logisim! Additionally,
you can think about using a multiplexer to determine which ALU function will be performed
