Altera Quarts II 4bit ALU design

[sham_rulz]

Homework Statement

Hello!
As a part of my course i am required to produce a 4 bit ALU using altera quartus. However i have very little experience with the software and cannot continue.
the input data is 2 4bit numbers A & B. The data should be read by the positive edge trigger of a clock plus and the data has to be output at a later pulse.
A and B are 4 bit binary numbers where A is greater always and the output is a 5 bit binary number.
IP instruction
0 0 Add A and B
0 1 Subtract B from A
1 0 Multiply A by 2
1 1 Divide A by 2

Homework Equations

The Attempt at a Solution

I tried solving this using the megawizard plug in manager where i found the ALU's for the functions but i cannot implement them in the design. Also am i supposed to use flip fllops or registers?
Any help would be appreciated!

Hello!

It sounds like you have a challenging project ahead of you. Don't worry, with some guidance and practice, you'll be able to successfully complete it. Here are a few tips to help you get started:

1. Familiarize yourself with Altera Quartus: Before attempting to design your ALU, it's important to understand the software you'll be using. Take some time to go through tutorials and familiarize yourself with the different features and tools available in Quartus.

2. Understand the input and output requirements: It's important to have a clear understanding of the input and output requirements for your ALU. In this case, you'll be working with 4-bit binary numbers for A and B, and the output should be a 5-bit binary number. Make sure you have a clear understanding of how these numbers are represented in binary.

3. Use the right components: In order to design an ALU, you'll need to use a combination of logic gates, flip flops, and registers. Make sure you understand the purpose and functionality of each component and how they work together.

4. Break down the problem into smaller parts: Instead of trying to design the entire ALU at once, break down the problem into smaller parts. Start by designing the logic for each instruction (add, subtract, multiply, divide) and then combine them together to create the full ALU.

5. Test your design: Once you have a working design, it's important to test it to make sure it's functioning correctly. You can use simulation tools in Quartus to test your design before implementing it on hardware.

I hope these tips help you get started on your project. Good luck!

Dear student,

Thank you for sharing your project and asking for help. I am happy to offer some guidance and suggestions for your 4 bit ALU design using Altera Quartus.

Firstly, it is important to familiarize yourself with the software and its features. I suggest going through tutorials and online resources provided by Altera to gain a better understanding of the software and its capabilities.

Next, for your specific project, you will need to design a circuit that can perform the four operations mentioned in the instructions. These operations can be achieved using logic gates such as AND, OR, and XOR gates. You can also use the built-in ALU blocks provided by Altera, but it is important to understand how they work and how to implement them in your design.

In terms of flip-flops or registers, both can be used in your design. Flip-flops are useful for storing and synchronizing data, while registers can hold data for a specific amount of time. It ultimately depends on your design and what you are trying to achieve.

I suggest breaking down your project into smaller tasks and tackling them one at a time. This will make the design process more manageable and easier to troubleshoot any issues that may arise.

I hope this helps guide you in the right direction. Remember to always consult with your professor or classmates for additional support and clarification. Good luck with your project!
