this just gave me the 'aha' moment. thank you!!

[@ibrahimnadir]

Perfect explanation. Calm, direct, accurate and makes perfect sense. This is how tutorial should be.

Best video for understanding the direct mapping. Thank you for your effort.

cant find a better explanation for direct mapping across youtube!!

[@guptagaurav916]

Probably the best way to explain this! Thanks a ton✨

[@Sir-Extremity]

Very good explanation and quality video. Thank you for your effort.

the term 'cache miss" and 'cache hit' are well-explained. Thank you

[@thedrunkmonk8386]

Good looking video and explanation. Thanks

[@zy6001]

Nicely explained and cleared my doubts! Very much better than my university lecture notes :/ Thank you very much!

[@Ravikumar-xj9fv]

PRecious explanation, no further doubts about cache addressing, tags etc after hearing this

[@bombombakudan2831]

Thank you SO much for making this video!! It's very helpful and clear

[@MiottoGuilherme]

Thanks man, great video!

[@mnbvcxz1621]

Wow it isgood clear neat and perfect.

[@santoshkumar-uw3ql]

Nice explanation, I would recommend previous and next video links in the description.

[@hirenpatel6118]

thank you, this is probably the best explanation i've found! one question, is it safe to say that block size must be equal to page size? edit: some research later, it seems that block size is fixed and it can equal page size but doesn't have to be.

[@rayyoung2154]

Thank you very much! Very clear.

[@radiagulzan]

this was so great, thank you !

[@lailadaraghmeh829]

perfect explanation, thank you

[@user-hn7tm6mb4k]

Thank a lot. this is super help for me.

[@Calm_Energy]

Now the addresses in these examples would be for a "pretend system" because, on say an x86, the addresses would be 32bits? The breakdown(tag, index, offset) would be the same proportions though right?

[@amanxo1]

amazing - thanks a lot!

[@petitoursbrun5619]

thank u so much, great video

[@nhatminhnguyenquang7965]

thank you so much for this tutorial

OMG thank you so much !
Something so easy but also quite often poorly explained.
Not gonna lie, I was "scared" by your accent (not your fault) but you surely know how to share your knowledge !

[@thisissharief7651]

awesome highly suggesting of bech students of jntuk kakinada
for cao subject

[@gopaldas7905]

sir please upload more video on pipelining...

[@DanielRamirez-di4po]

Amazing video! Gave me the missing link of understanding what the hell I was reading in the classroom text.

[@jarrydnii9993]

You're amazing!

[@JacobDiaz]

So basically if the the cache is a miss, the CPU will go to the main memory to access the data and load it into the cache, and if it is a hit the CPU will load the data straight from the cache? I am just a little confused as to if it is a miss, will the data not be pulled until the next clock cycle?

[@puddingspy9837]

great vid

[@harendrasingh_22]

2:58 finally got it.

[@vedantshirodkar]

Nicely explained

[@aronquemarr7434]

Great.

[@maxhmetonxrono]

Ppl you have to watch this video it is so clearly example !!!!!

[@brandonnoronha5535]

What is the use of block offset then after decoding?

[@AakashKumar-root007]

Thank you sir like really ,

[@pilotandy_com]

Im still not sure how to write back to main memory, but this is a start.

[@mk9834]

thanks help alot!

[@kotshifotshi739]

perfect thank you sooooooooooo muchhhhhh!

[@Noufs101]

THANK YOU!

[@livb4139]

tag bits are inside the cache right? one per block?

[@tunahanburakdirlik1537]

thanks for your effort sir
ı have an qustion; in the (6.03) block size how become equal to 8 bytes , what is the formula of block size?

[@maqalmulla2891]

It was just an assumption. So there is no formula. c:

[@azamvisuals]

Thank You sir !!!!!!

[@ashupipalia6046]

great sir

sir plz write full form instead of using abbreviations. that would be awesome

better than my professor

[@saintboimike]

[@maq17]

How do we know block size=8 bytes? explain plz

[@SuryatejaPericherla]

In competitive exams like gate they will mention what will be the size of a block in the question.

[@thisissharief7651]

confused with bits and bytes in this lecture but good effort
