This is the BEST computer architecture course out here hands down! The professor makes sure the common thread that runs through all the lectures doesnt get broken, coherently reviewing past lectures and hinting at what’s to come in each lecture, which makes it so easy to follow along.

[@guliyevshahriyar]

Yes, right.

[@robertforster8984]

It is like being in class with your eyes closed. But the teacher makes it worth it.

[@easterPole]

Welcome back prof. ! , Missed you in the last lecture :)

[@sergeyrar]

Studied about MUXes 10 years ago... great refresher :D 51:00 Really cool stuff

[@kabylkas]

First of all, thank you so much for making this course available for anybody in the world. I, personally, have been taking a lot out of these videos so far. I am taking this class seriously: I follow the class schedule on the website, work on all of the homeworks, labs, and read all recommended readings. Unfortunately, some of the tools for the lab require to connect to CMU ECE server. Which, obviously, requires being CMU student. At this point, the only work-around I see is buying actual FPGA dev kit. However, I was wondering maybe you can suggest something to be able to work on the labs without having CMU student account? Thank you

[@niteeshmastaiah2120]

hi can you share the solutions for lab 1

[@the-Cker]

You've done a great job by sharing this materials and videos. I'd love to be a CMU lad I'll definitely try to get into MS-IS program of your INI institute.

Prof.Onur Mutlu its so good to see you putting such an extraordinary effort to educate the students around the world.Thanks for the free lectures. Have you authored any book/books on Computer Architecture? I hope you reply...

[@rafaelespericueta734]

First off, I'm grateful to have such talks available to watch! :-) Now for a pet peeve... Really, what's wrong with people controlling cameras for technical talks? It's so frustrating when you're trying to read a slide, but barely have time to scan it quickly. Then we get to see the lecturer talking ABOUT the slide?! Really, it would be much better to ONLY show the slides with the talking. So often I find myself getting angry when I can't see the information the lecturer is talking about. And this is the norm rather than the exception.

[@josephthomas1790]

Maybe just open the link to the slides on another tab for a side by side view?

If the camera man was at the NBA finals, he would be filming the WC entrances, the physiotherapists etc...

Great class! Thanks!

[@kushalvangara5104]

1:42:30 time was stopped, please fix this.

[@CMUCompArch]

+Kushal Vangara This is unfortunate. We will try to fix this. The remaining slides covered in the last 5 minutes are slides 75-80 here: www.ece.cmu.edu/~ece447/s15/lib/exe/fetch.php?media=onur-447-spring15-lecture5-uarch-afterlecture.pdf

[@bartsomerson2099]

Anyone know the name of the Elsevier book referenced in the lecture slides?

[@lebanbo55]

1:42:30 time was stopped.

[@GAVVVR]

Reloaded the youtube page, but of course it did not fix the problem at the end of the video. Anyways thanks for lecture :)

[@bobanmilisavljevic7857]

Did you watch the newest lectures?

[@yz4289]

The camera doesn't need to follow the movement of the professor all the time.

[@AlphaFoxDelta]

They have the slides available in the description if that helps

[@robertforster8984]

The slides are available in the description, but yeah. It is a major inconvenience The camera man made a bad mistake.

[@kesavachintada1280]

can anyone suggest me a text book that goes with this course?

[@ziyuhuang6237]

For lab1, how to get the spim447? Thanks!

[@Fnargl99]

just an fyi. slides 78 and 79 contain the same link. 78 you say "Here are some references where you can learn more" and then on 79 "For more, see:"

[@carstenklein4568]

PC+4, erm, are we talking about fixed length instruction sets or some harvard architecture?

[@intvnut]

PC + 4 because the instructions are fixed at 4 bytes each. I have a different question: What happens when you issue an unconditional jump from the last word in a 256M segment? If we're really concatenating w/ PC + 4, the upper 6 bits of the PC will point to a different 256M segment, unless the PC+4 computation itself only affects bits 25:2 of the PC. (Bits 1:0 of the PC are always 0.)
