What is AXI (Part 1)

In this video I give a brief overview of the AXI protocol.

[@yaranaser8886]

Short, concise and straight to the point. Thank you so much, you're a life saver!

[@DillonHuff]

Glad you liked it Yara!

[@aienbalosaienbalos4186]

Gotta say, I like this style. Simple, clear and direct.
Also commenting to let the algorithm be aware that this video is good

[@DillonHuff]

Thanks Aienbalos!

[@naman-sharma]

Great explanation! First building the right intuition and then explaining the concept helped me digest the content easily.

[@AbarajithanGnaneswaran]

This is beautiful. I had a lot of confusion about buses in the first few years of my undergrad. Then I figured out this way (BRAM interface, how to generalize it, AXI stream and AXI) and this is how I teach it. Just found your channel. Will be sharing this with my students.

[@DillonHuff]

Glad you liked it! I agree that teaching the progression of different memory interfaces is the right way to do it. I'm surprised it isn't more standard.

[@peterxiau]

short, clear, and easy to understand. thank you very much.

[@apprentice2101]

This is very a clear and intuitive explanation! Thank you so much!

You're welcome!

[@christianngameni1538]

Great explanation of not only the HOWs but also for the WHYs of the AXI-Lit bus protocol

[@DillonHuff]

Thanks Christian.

Hi Dillon,
Video is very informative and your explanation is very good and it helps to understand the protocol very well. Very good job. Keep making videos like this.

Thanks Harish! I'm glad you liked it.

[@merrickryman4853]

Great overview! Could you do one on AXI in the context of FPGAs?

[@runninglanguage7384]

Very clear! Thank you very much!

Thanks Rejiu!

Thank you for this video

[@muralikunapureddy8240]

You r targeting a small minority group in engineering sector which is hardware... Still 7k views is a big in this sector... I found this video after 1 year of upload.. feeling good at least now.. great work...

[@FPGA_Arabic]

magnificent!!

[@santoshshetty2358]

Hi Dillon, thank you for the video. Nice and clear. Can I get access to subsequent videos?

[@DillonHuff]

Thanks Santosh! The second video in the series can be found here:

I have not finished the series yet, so only parts 1, 2, and 3 have been uploaded so far.

[@ramonnepomuceno5299]

Great video Dillon!

[@DillonHuff]

Thanks Ramon!

[@ramonnepomuceno5299]

​@@DillonHuff Can you explain the difference between AXI stream, AXI MM and AXI lite? thanks in advance.

[@DillonHuff]

@@ramonnepomuceno5299 I'm not familiar with AXI MM so I can't comment it. I would say that the biggest difference between AXI stream and AXI lite is that AXI lite is a protocol for interacting with a RAM, so the transactions in the protocol are reads and writes to *addresses* in memory. In AXI stream the data transfer is just a sequence of data words flowing from the master to the slave.
The youtube comment section is not a great medium for this so perhaps I should do some videos on the differences!

[@aleemrehaman]

Hi Dillon , when are u planning to do the remaining videos?

[@RandomHubbb]

love it! your style is the best. can i keep you in my library? 😂

[@rick_er2481]

Great video thanks!

[@DillonHuff]

No problem!

[@shawn9652]

Video on different transactions like out-of-order etc and ID tags will be helpfull

Oh god, at last an engineer who can explain things.

[@alexandrosiii5676]

Let me ask, all the videos in this series are talking about Full AXI (AXI Memory Map) right?

[@DillonHuff]

I'm not sure what you mean by "Full AXI". They are talking about the protocol in part A of this document: developer.arm.com/documentation/ihi0022/e/

[@sirilroy1005]

Great Work. Everyone can easily understood the protocol. Could you please create videos explaining AXI side band signals ?

[@DillonHuff]

Thank you Siril! I'm not sure I'll have time soon, but its on my TODO list.

[@theinterruptedlife1783]

But, there are ready signals, slaves and masters can delay responses. There are dedicated channels for write response and read channel itself has a RRESP signal. What about those? Am I missing something?
Very nice intiution explanationthough, I will see the remaining videos too
EDIT::
Oh ok, I missed that you mentioned all this when one does not use AXI. Well I will keep this comment anyway for record
