A TLB is a CACHE MEMORY which is stored inside a PROCESSOR and its size is very less and its veryyy faster because it is inside a processor so the accesing time will be of nano seconds and TLB contains the most recently used FRAMES and TLB has HIT RATIO > 95%...A typical TLB contains last 16 entries also called level 1 TLB and lvl2 contains 256 entries. This are some real world values :)

@vaishalichanana1562 7 лет назад

one question. how TLB stores page and frame info for all simultaneous processes as there could be different page tables at same time?

@RakeshKumar-xr8ku 7 лет назад

There will be only one TLB as it is a special hardware. So only one process can use this TLB at that particular instant of time. whenever context switch happens(i.e.. the current process will go to sleep state and CPU will take up new process which is in ready state) then this TLB will get cleared and the page numbers and corresponding frame base addresses of a new process will get stored in TLB again. Each and every process will have their own page table. CPU will execute only one process at a particular instant of time. So we will not be having multiple page tables for CPU at same time.

@aveenashmandhwani4034 7 лет назад

In modern architectures, there could be 2 or 3 tlbs. As you know we have now multi-core processors, there could be more than one processes running at one time means more than one page tables. So for that Modern architectures facilitates you maximum 3 tlbs in one pc. So each process has their own tlb.

@republic2033 6 лет назад

@syedmoiezbukhari2972 6 лет назад

@KNOWLEDGE GATE, can you please tell that is the size of TLB is fixed or its dynamic? How will we fix the size of TLB ?

@edublox4790 6 лет назад

its fixed because its hardware

@ANGAYARKANNI_A 6 лет назад

super sir.thanks

@JV-fm5ul 5 лет назад

watching this video 3hrs b4 endsem exam as my first video onsubject, lmao, what an irony

@aag2995 6 лет назад

The speed of copying or downloading does not increase because TLB starts caching. It increases because TCP increases its window size.

@krishnasoni5173 6 лет назад

thank you sir.. keep it up ❤️❤️

@monikasoni8418 5 лет назад

Sir..what is the difference between ptbr and tlb..?

@ishansharma868 5 лет назад

Sir you had said that TLB has more or less 32, 64, 128 locations. So does it mean that it can't store frame number of more than 128 pages of a process.

@anuragmanikkame8568 6 лет назад

How cpu gets instructions for creating logical addresses as instructions are stored into disks (if I am not wrong) ? suppose I have echo "welcome" program , so logical address with instruction (echo "welcome") or same instruction will be trasferred to main memory ...how cpu will get to know it has to run echo "welcome" instruction ...can anyone explain me ??

@neerajattri9070 7 лет назад

@ujjwalagarwal6325 5 лет назад

Sir , In one video tell us about your COUNSELING BUSINESS. Indians Will get GOOD Help Thereafter.

@shethnisarg3049 5 лет назад

I have one doubt.. if TLB is common for all processes then how would we know to which process the entry in the TLB belong?

@rimmonbhosale9938 5 лет назад

For the same query refer to the above video at 11:50+ approx.

@yavdhesh 7 лет назад

Superb!!

@sonuagarwal7679 4 года назад

What will happen if TLB will full and there are some pages remaining for a process ? Will it swap some page no. and frame no. ?

@44_shubhamsharma75 4 года назад

If the TLB is full, we have to select a page which has to be replaced in TLB. We do this by using LRU, MRU, FIFO page replacement policy.

@nasirabibi25 7 лет назад

thankyou sir! it helps alot. respect from pakistan :)

@deepakbahuguna6231 6 лет назад

Sir could this happen that page table entry found in tlb doesnt exists in main memory coz of some page replacement policy?

@richavarghis4603 6 лет назад

YO! WHY IS EVERYTHING SO COMPLICATED :)

@uditjec8587 3 года назад

how many number of TLBs are there in cache?

@millenniumgames5405 4 года назад

What will be the access time of TLB? Won't it be O(n)

@c--rayashreemondal1913 7 лет назад

If there is a TLB then is there any need of page table?

@RakeshKumar-xr8ku 7 лет назад

scenario 1: first TLB will be empty, when process starts its execution it will check the page number in TLB which is empty, then it will check the page number in page table and finds the physical address of the instruction. At this time the page number will get stored in TLB. This way the TLB gets filled(Please correct me if I am wrong) scenario 2 : TLB is a special hardware and it is of small memory. TLB is capable of storing limited memory. what if the size of page table is more than the size of TLB? Obviously we need page table along with TLB. The concept of TLB came into picture just to reduce the access time of an instruction from main memory. The cost of having TLB is very high. so we will be having less number of TLB in our system(say 1 or 2 ..)
