CS-224 Computer Organization Lecture 06

[@ivanjuniormtz]

This professor rocks! His presentation is very clear and enthusiastic. I'm glad Billkent U. made those classes available. Thank you.

[@AmyAndrewAdventures]

Man I wish I had professors like this!

[@faikerenaltun828]

amazing lectures. online free education is seriously one of the biggest revolutions

[@chengsun8567]

How I wish I could have a professor like this!

[@follklor9976]

this professor +professor leonard+khan they are avengers amazingg

[@ThuyNguyen-bu9ge]

You are a life saver Professor, plus you have a really nice shirt.

[@sammyiboi]

I love this professor so much!

[@syed22]

so much passion for what he has spent his life on. From a student, Thank you professor. Unlike most other students i see in the comments my professor is great its just i need extra help understanding this stuff and you are extra help and them some lol. Thank you again sir Syed

[@xx03_p19]

What a relief from lecture 04 and 06. I hope I haven't missed anything really important.

[@valentinochristian936]

shech?

[@gingozoldyck9625]

yeah,that guy sucks

[@harry-fl6tf]

​@@valentinochristian936 you missed "shech". that's what the computer says

[@takshpatel8109]

Il watching this after my college,just to improve my knowledge but i wish I had found this videos when i was in college. Amazing videos

[@Sagimoto]

Im so glad this professor is back and not the one from the previous video!

[@NadaAhmed-zx1ru]

Fantastic energy, great explanation (Y)

[@nspower9488]

hello

[@hurryharry8]

an amazing lecturer

[@maldinila]

Very clear lecture. thank u !

Q: (29:30). About memory locations that a register can point to. It can point to, up to 2^32 + ??? For example, N(R) means address of N+2^32. So how big can the N be??

[@gilzarfati8252]

SW and LW are instructions of type I, so you have 16 bits for an immidiate/offset value. N must fit in 16 bits length. The all instruction is 32 bits. from left to right: the first 6 bits is for instruction code (for example SW or LW etc.) then you have 5 bits for the address of the register that holds the base address in main memory; 5 bits for the other register, and 16 bits for the offset(N).

[@melonsfive4815]

A ha! Thanks a lot~~

[@hamzanasir1590]

Great lecture Sir. 👍👍👍

[@mecwave4726]

25:30 i believe was the best definition of the society. Or pretty much everything.

[@kenkaniki4299]

How great !!

[@melonsfive4815]

Q : What makes the register go faster than memory? That's because signals go through small number of decoders in register than in memory? It that's the reason, can we say 'propagation time is different in register and in memory' ?

[@johnb1391]

Yes, the register is faster because it's closer to the ALU. Accessing memory would be a longer trip time, increasing the latency (latency being the amount of time it takes to do a process. So lower latency = faster results). Saying "propagation time is different in register and in memory" would be true but it'd be a bit too broad of an answer. It doesn't explain *why* the propagation time is different. So a better reason to say would be the register is faster because it is closer to the ALU, meaning it has to cover less distance to perform the same operation. Since we can't really change the speed of an electron we can instead increase performance by changing the distance an electron would have to travel. If that was confusing then a more succinct (or simplified) way of saying it would be "the register is faster than memory because propagation time is faster due to less distance between the ALU and the memory location" (note: memory location in this context does not mean location in stored memory. It means the location of a stored value. Memory location in this context is referring to the register location [r1, r2, ..., r31]).

[@melonsfive4815]

Your answer : less distance (causing electrons travel through shorter distance). My answer : signals(electrons? voltage change?) have to pass through less number of decoders (since each decoders will take time to reflect(or process) it's input change). Which one do you think will be there answer??

[@theprodev]

Registers are purely Sequential and that's why it is fast and that's why close to ALU, and that in turn increases use of it than main memory.

[@melonsfive4815]

Thanks a lot ^^

In case you miss guys 26:53

[@PortugueseLanguage]

Thank you, thank you and thank you again.

[@fishyperil2153]

lol what contrast compared with the guy from the last 2 lectures...had no idea wtf that guy was talking about

[@xyzzyx9357]

😂😂😂

[@premuhendis5419]

I love you professor

[@KulvinderSingh-pm7cr]

example of hegel was great, thanks

[@psaha787]

Hello guys do you know where I can get the digital design lecture series of this same professor, thanks !

[@wjl3703]

so excellent! how can I get all the slide?

[@AlimamiHD]

2020?

[@raviahuja9287]

well zero is called as sifir in turkish... glad to know that

[@SNIP3SHOT518]

The amount of shade thrown at these students... usually deserving except the whole 2^25 thing not intuitive if you didn’t already know

[@zacharycollins1817]

Fantastic.

[@Felix-wh8pz]

perfect

[@milesdavidsmith]

This guy is like a mixture of Mr. Rogers and Bill Nye

[@toasawamura364]

How do you know about Rogers??? Carleton

[@erenizliyor]

omg this lecturer can also speak turkish

[@olzhasdossaibek9095]

Z E R O dislikes. 226 likes. 227th is mine

[@FaxNight]

After found this, i feel like i'm totally an idiot since i wasted valuable 80 mins of my life for watching the previous 2 episodes, and taking a roughly "review"ed lesson after that, even through it's much better, but still consider quiting this series.

[@dineshgupta8331]

Great Lectures...I see a bit of gayness in the professor....😄
