Instruction Set Architectures

We've seen logic components in action in an earlier series, but how do we work with them when they are all packed together in a CPU? In this episode, we discuss instruction sets to better understand how we can control a CPU without in-depth understanding of its construction!

8 years later i still find this helpfull, am about to start my cs

[MoeTavern]

8 years later I found this video as a newbie to CS, thank you so much!

[nguyenminhhoang]

dude this video is vital for all students who are studying computer architecture...I like the way you explain clearly.

[ivykorah]

You should totally get award for best teacher of the century. You just help me get over 3 weeks of frustration and sleepless nights. I found this lecture just when I was about giving up on choosing my current course. You did for me in 13minutes what 6 2hrs long classes could not do for me. No technological jargon, just simple terms. Thank you so much

[memeingthroughenglish]

This is great! I love how the information is displayed with the colors. I started color coding my notes and it really helps break apart the information and categorize it, much more than with explanations for me!

[TayoEXE]

Seriously, this cleared up the overall point of ISA better in 13 minutes than my professor did over the course of two 2-hour lectures. I horribly confused me, but this is helping me definitely get going on my Assembly lab.

[lovezonee]

This is very simple and efficient videos.. loved it.

[graff]

After watching multiple youtube videos on ISA, I can say this is the one that worked for me. Subscribed. Thanks!

[amusa]

can't believe I am seeing the same dude after how many years... nice video

[raghavpatne]

dude you should totally do many more videos like these

[dvl]

DIS IS GOLDEN! I finally understand (sort of) how computers work
and it's just as tedious and difficult as I thought it would be BUT there are few tricks here and there to make it easier like the assembly language
I didn't know about that.

[ezrasalamat]

This video is brilliantly made... simple, straightforward, and well constructed explanations. Than you for uploading this!

[Calm_Energy]

great job taking us step by step through those "levels of abstraction" aka "the levels of compilation."

[unknwnrge]

thanks for saving Earth agaisnt Shao Kahn Mr. Liu Kang, I happy that now you are enjoying your life as a teacher, unexpected.

[ColeslawProd]

Cool! Nice coincidence. I've been making a computer in logisim (that I will probably never finish), and the last thing I did was think about what instruction set it should have.

[engineerwannabe]

Good video, concise and clear. Good english pronunciation as well. Thanks

[dta_yoon]

Thank you for the simple and easy to understand explanation!

[AT-zrtv]

Haha, I love how Assembly is presented as an easier solution than typing the bits directly. :) Great video man, very helpful and well explained.

[johnnymars]

I have never ever left my comment feedback on youtube for anyone. But you are the best, thanks for a really simple explanation. :) Respect Bro!

[icarox]

Nice job, man! Cleared a lot of stuff more than reading technical books.
