AMBA AXI Infrastructure Based on Xilinx FPGA IPs and Verilog

Understanding AXI: The Foundation of Modern System-on-Chips (SoCs)

Why AXI is Essential

The Advanced eXtensible Interface (AXI) is a fundamental protocol underpinning virtually all modern processors, controllers, and complex systems. If your work involves interacting with a processor or any substantial system architecture, you'll inevitably encounter AXI buses. As Artificial Intelligence (AI) continues to advance, the importance and prevalence of AXI are only increasing. This course provides a comprehensive understanding of the AXI protocol and its key components.

Who Should Take This Course?

This course is specifically designed for FPGA designers who utilize AXI-based modules in their designs. It's also an invaluable resource for engineers just beginning to work with the AXI protocol. Graduates seeking FPGA or SoC developer roles will find this course particularly beneficial. In my experience, AXI proficiency is a consistently sought-after skill among new hires in this field.

Course Content: A Practical Approach to AXI

This course offers a practical, bottom-up approach to mastering the AXI protocol family. You'll gain the skills to confidently understand and utilize AXI-based IP (Intellectual Property). We focus on the core concepts and practical application of AXI, without delving into FPGA board-level specifics. The emphasis is on simulation-level understanding, not FPGA board implementation.

The course begins with a foundational understanding of simpler AXI protocols:

• AXI-Stream: Learn the basics of data streaming with AXI-Stream.
• AXI-Lite: A detailed exploration of AXI-Lite, ideal for control and configuration interfaces.
• AXI Protocol: A deep dive into the full AXI protocol, building upon your understanding of AXI-Stream and AXI-Lite.

Throughout the course, we'll implement these protocols using Verilog, providing hands-on experience. We'll also review the official ARM specification for AXI, equipping you with the knowledge to easily navigate and understand the detailed documentation.

Bonus: Vivado & IP Exploration

As a valuable addition, you'll gain introductory knowledge of Vivado and its integrated AXI IPs, along with simulation methodologies.

Special Thanks

I extend sincere gratitude to Eduard Vardanyan from ARM for his invaluable support in developing this course. His extensive experience and deep knowledge of AXI were instrumental in making complex concepts accessible.

Important Notes:

• Course Materials: All course code and materials are available for download on GitHub.
• Verilog Familiarity: While not strictly required, a basic understanding of Verilog and hardware concepts is highly recommended. Several lectures will benefit from this background.
• English Language: I apologize in advance for any grammatical errors or imperfections in my English. I've strived for clarity and accuracy, and hope this will not hinder your understanding of the material.
