Sir ur teaching style so simple that everyone can understand without any doubt

WOW... You have explained this concept very nicely sir ... Thank you so much !!!

[@YuktaVarshney]

🎯 Key Takeaways for quick navigation: 00:00 Virtual *memory provides an illusion that processes larger than main memory can be executed, overcoming the limitation of finite main memory sizes.* 02:26 Virtual *memory divides processes into pages, bringing only required pages into main memory based on the concept of locality of reference.* 05:37 Swap-in *and swap-out operations, or roll-in and roll-out, manage bringing pages into main memory and replacing them when needed.* 06:36 Virtual *memory allows executing processes without limitations on their size or number, despite the constraints of limited main memory.* 07:29 Page *faults occur when a CPU demands a page not present in main memory, leading to a brief interruption in control and a switch to the operating system.* 12:38 Page *fault service involves searching for the required page in logical address space, bringing it from the hard disk to main memory, and updating the page table.* 14:29 Effective *memory access time is calculated as P times page fault service time plus 1-P times main memory access time, highlighting the impact of page faults on overall performance.* 19:12 Excessive *page faults can lead to threshing, causing degradation in CPU utilization and overall system performance.* Made with HARPA AI

Omg I never knew this formula has a proof also... LPU was blessed to have u sir ... Bad luck that I never got the opportunity to learn from u physically.

Also, In TLB miss occur the TLB is updated with page number and frame number so in future if same page is accessed no need to go the page table.😊

[@parakhchaudhary7453]

One unique thing about every Gate Smashers lecture that I have cherished since my Btech days: All videos always have: -> Explanation of prior concept required to understand this one - Provides context. -> Explanation of need of this particular concept - Provides motivation. -> Explanation of how the need is satisfied with the current concept - Provides insight. Salute to you sir. Thank you for your selfless contribution towards the Indian CS Engineering scene overall.

Page-table cached goes into TLB, part of MMU. Page cached goes into Primary Cache, sec. Cache

[@fyune]

please help me with my confusion : when a miss occurs first it checks the TLB then it goes for Page table, and finally to the main memory --> so why not the effective memory access time is: TLB + Page Table Time(x) + Page Access time (x) = TLB + x + x? but it is actually ( TLB + x) + (TLB + x + x) --> even when we are accessing the TLB just one and shifting to page table? Sir, said both combined is the total time for a miss, but i think its just (TLB + x + x). Thank you in advance for any assistance you can provide.

efficient memory acces time= h*(c+m)*(1-h)(c+2m) h=hit ratio,c=tlb access time,m=tlb acces time

[@yuvaraniyuvarani2277]

All videos r good sir please upload in English

[@gautamtiwari7087]

❤

[@pranavvenkata475]

small correction : Effective memory access time is given as h*(c+m) + (1-h)*(c+2m) where h-> hit ratio of TLB. C-> TLB access time m -> memory access time. Great lecture btw.

[@thepriestofvaranasi]

Is this formula correct?

[@pro1world573]

Hey, he wrote hit in the top, he wrote the formula right= h(hit(tlb+x) +(1-h)(tlb+2x)

[@skullbhaiya9508]

at 10:27 in case of tlb miss as you have written there EMAT=(TLB+x (but if its tlb miss then we didnt access the MM then we dont need to add x for tlb misss) )+Miss(TLB+x+x) so may be it will be like EMAT=TLB+Miss(TLB+x+x) isnt it?

[@minivashishta9288]

thanku,sir

[@irshadahammedop2270]

Sir. Please Make class on multilevel paging ( with how logical address is dividing)

[@suvamgurung3393]

can you also explain about software and hardware managed TLB with their advantages and disadvantages?

[@kritikagoel2782]

Hi Sir, One Doubt, For the miss case, why the EMAT will have X in (TLB + X)? If it was a hit then X will be the time taken to find the frame in Main Memory, but if in TLBitself fail then it will reach to page table below the TLB right? So EMAT = (TLB) +(TLB+X) ??

[@poojachauhan2709]

Sir iss TLB ko bhi MMU he use krti hai na?

[@komalnalla7591]

Sir pls also provide some notes😇

[@jamalahmad3378]

Sir cpu to page no generate krega to page number se kaise TLB me frame number kr payega? Kya jo tags h vo page numbers hi h??

[@monareddy9111]

Sir, How is it decided that which page number entries go into tlb ? Really appreciate your videos.

[@muraripandit5706]

This may be reported by OS

[@karishmasingh9889]

Jaha notes bhi provide aap karte ho for computer science students these are preparing for gate exam and isro exam

[@flagship5]

sir, which frames are residing in tlb

[@sangitaadak1337]

Sir page fault occurs in the page can't be present in TLB. Is it true or false ? Sir please reply.

[@GateSmashers]

Yes

[@sangitaadak1337]

Ok sir thank you.

[@shreyaswaikar4400]

Sir, essentially TLB is storing page table itself. Aur TLb me nhi toh(Miss condition) toh MM k Page Table me kaise hoga? yeh toh page fault hua na! Please clarify this one.

[@yashgupta3127]

I have a doubt if anyone could clear,to find the page table do we search the main memory page by page? If yes then how accesing a page table time and accesing the frame of that particular process is same? Because page table will give us the physical address of the particular page we are finding and we directly go to that address but for page table we have to search it.

[@shivnandantiwari7489]

Sir please make test series of gate also

[@aliakhan5497]

Consider a paging system that uses 1-level page table residing in main memory and a TLB for address translation. Each main memory access takes 100 ns and TLB lookup takes 20 ns. Each page transfer to/from the disk takes 5000 ns. Assume that the TLB hit ratio is 95%, page fault rate is 10%. Assume that for 20% of the total page faults, a dirty page has to be written back to disk before the required page is read from disk. TLB update time is negligible. The average memory access time in ns (round off to 1 decimal places) is Sir pls explain
