Set associative cache

[@robrenesp]

I've been struggling with different kinds of explanations for what Taag, Set and Offset are about. This video, combined with my own studies, finally cleared it up for me. Thank you very much! What I was missing in my head was the clear overview that Set and Offset are just bits of the address, and then where they are used in the big cache table. This video was just what I needed!

Thank you so much!!!! Finally find a good video to help me understand the set associative cache!!!!!

[@Clint945]

Thanks for these videos, the diagrams really help explain what's going on compared to reading walls of text trying to describe the process.

[@capellidipaja]

These video you made are gold my friend =)

[@shivangiverma819]

Great explaination....i had so many doubts ...really thanku for this video ...best explaination

[@Eric-ok2rx]

Phenominal videos. You should consider introducing cache design implementation strategies; ie, write allocate, write through, write back, no write allocate, etc. Similar and equally needing of a great youtube explanation. Thanks a bunch!

[@siddharthamondal2883]

Thank you such short and nicely explained video sir. All three cache mapping technique very easily explained. Thanks for this useful upload

[@ThuyNguyen-bu9ge]

You are amazing! I value your teaching Abelardo!

[@dlwnsdyd0331]

The best cache concept explanation! thank you so much

[@miguelfernandosilvacastron3279]

Many thanks. in 10 minutes very concise explanation.

[@sanchezchris95]

These videos are much appreciated, thank you.

[@georgemiller3745]

Seriously thanks a lot, this was a life saver. Easy to understand and very clear: I would like you as my teacher! :D

[@VikasSharma-lo7cd]

Very good explaination. Thanks a lot

[@ilikew101]

Excellent explanation, thanks!

[@IcarusFlying]

One thing he didn't explain, and which confused me until i figured it out was how the sets correspond to main memory. Every multiple of eight(in a eight set cache) can be used in set 0, so you can have two blocks of a multiple of eight in set 0, if that makes sense. Of course if there is a third block from main memory used, there will be a conflict in the set, and one block in the set of the cache will have to be replaced

[@Jekttt]

Great video. Very well explained. Thank you.

[@karanmehta93]

Nice Explanation. Loved a lot... But please add the content to show that the cache shown is NOT 4-way set associative. It is always possible that people will perceive it wrongly. Add details on "ways" in set associative caches.

[@yuchongHu]

terrific explanation :)

[@dogsnout]

Very helpful! Thank you!

[@corneliuskemboi9636]

Fantastic explanation

[@salmanjaved6296]

Very good explaination ... Thank you so much!

[@Allen-oc1tr]

Awesome video

[@selvamv6740]

Good explanation , thanks.

[@karimtamani4661]

you are the best bro . tankx

[@michaelszczech9829]

In a two-way set associative cache which has 256 slots and 16 words per block. Would the total number of blocks be be 512 with a total of 8192 words?

[@spikeyfish2]

Thanks - this helped a lot :)

[@corneliuskemboi9636]

Try and give us more effects on cache memory and how some one can do way with them for him or her to avoid the crack down of the system.

[@nguyentanhai]

You are amazing. ;)

[@PiyushWaradpande]

Nice explanation! "PLACEMENT" didn't really get placed properly on the page, but hey... its flexible :D

[@rohitrayala7987]

helped me lot..thanks man ;)

[@fethiourghi]

great explanation thanks

[@kevindhimitri8794]

So a memory address is d bits, containing Tag, Set, and Offset. What exactly is in the Data field of a cache block? Is it the memory address's Set and Offset-1?

[@jamalalkelani4439]

You are Amazzzzzing

[@darthattano]

Thank you very much!!!

[@Canadian2633]

papa john godbless for these videos

[@gemzzhou7606]

Thank you so much :)

[@alupci]

Thank you for your videos! I would really appreciate if you could provide us some examples with real figures. Does offset corresponds to word? I've been studying from some books where that field is named word. I am not trying to diminish anyone's work but explanation given there are not helping at all. Thanks!

[@commanderzx]

amazing

[@TechOnSteroids]

Thanks alot sir

[@PrasadHonavar]

different terminology used compared to textbook but nice video

[@satadhi]

hi buddy can you be more specific please that will be a great help

[@PrasadHonavar]

Satadhi Halder thanks but I have all my answers now. It's been 2 years now since I watched the video.

[@zidanm969]

you don';t take about index which come after the tag

[@shekharmangonda1129]

what is offset?

[@francescoesco123]

Since each line may contain more than one variable, the offset uniquely identify the position inside of the cache line. Let's say the cache is 128 bit long: in the same line it can contain 4 different float variables (supposing that a float is 32 bits), so the offset will be made up with 2 bits (LSBs) =)

[@shekharmangonda1129]

Thank you ☺

[@MeYou-ln9cm]

Karim. Algeria.thanks

[@NodeEntry]

I love you.

[@ruvinbsu]

Good explanation, but there are no examples

[@tayabsoomro]

You write very small, it's hard to see without full-screen. :/

[@rohitrayala7987]

helped me lot..thanks man ;)
