CS 202 - Problem Nine: ALU

Due: 04/05/2023

Goals

Create a critical part of the ARM processor

Objective

For this problem, you will construct an ALU for an ARM32 processor. It will support all the arithmetic and logical operations entailed by the ARM32 instructions we have looked at in class, as well as some other important ones.

Here is the desired behavior of the ALU

operation	result
0000	`operand_0` bitwise-AND `operand_1`
0001	`operand_0` bitwise-XOR `operand_1`
0010	`operand_0` minus `operand_1`
0011	`operand_1` minus `operand_0`
0100	`operand_0` plus `operand_1`
1100	`operand_0` bitwise-OR `operand_1`
1101	`operand_0`
1111	bitwise-NOT `operand_0`

Requirements

your work must be in a file called alu.circ
your implementation must be in the main circuit (you are welcome to create sub-circuits however)
your circuit must have three inputs: operand_0, operand_1, and operation.
operand_0 and operand_1 are 32-bits
operation is a 4-bit input
your circuit should have one output called result
result should be 32-bits.
the value of result should reflection what happens when operation is applied to operand_0 and operand_1.
you are restricted to
- input pins
- output pins
- splitters
- components in the Gates library (i.e., basic logic gates)
- components from the Arithmetic library
- components in the Plexers library

Submission

Upload your .circ file to Canvas.
