@aanishparuchuri4047 4 года назад

some good stuff It would be great if you could arrange your playlist in order for computer organization and also add the video "direct mapping problems" to it.

@arpitasinha4163 8 лет назад

Hello sir, I donot understand in the last part of video that why you have taken the cache tag no as- 00,11,10,11 i think it should be like- 00,01,10,11 because in your first eg you said that while mapping main memory block number with cache line no- you said that least significant bits (00) will occupy cache line 0. Similarly least significant bits (01) will occupy cache line 1 and so on. please help me understand this. Regards

@djigi2002 6 лет назад

there is a mistake 21.50 location in the video, u can find that he has written 1 as 11 under the tag column, which is i suppose wrong.

@bucky3300 5 лет назад

Tanmoy Debnath bulls eye 👁️‍🗨️ apart from that small mistake the lecture is osm and very helpful

@gauravgaur5014 5 лет назад

@@djigi2002The tag and line number need not be same,the tag if taken as 11 generates blocks 52,53,54,55 in the cache whereas the tag value of 01 for the same line 1 will generate blocks 20,21,22,23 in the cache.

@dharijan84 6 лет назад

Sir I never doubted your lectures until today so, can you please tell me how did that line at 21:19 appear creepily? It feels like i took a little detour in the middle of your lecture and went straight to Paranormal Activity series!

@crescenciomirandaferrol5027 5 лет назад

Sir, I think there is a mistake aronf 29:44 in the tags associated with the 4 block cache memory. What you say to be a hit, I think is a miss because second line is 01 not 11 as you wrote. Please, tell me if I am wrong. Thanks.

@noormuhammad7301 6 лет назад

@naeemshaikh6790 8 лет назад

At 23.27 while mapping the block numbers with the line number 1, i think there is mistake while calculating the words to be loaded in line 1. The correct words in line 1 should be 20,21,22,23. ( Tag for Line 2 is : 01 Line number : 01 so the address formed will be 01 01 00, 01 01 01, 01 01 10, 01 01 11 that gives u 20, 21 , 22 and 23). Check it out, I might be wrong in doing this.

@TastyLaserCakes 8 лет назад

Remember that Line #1 can hold the following blocks from main memory. Line #1 can hold blocks (1, 5, 9, 13). Block #13 can be represented by the following most significant 4-bits (1101). Breaking this into their Tag and Line# counterparts we have the most significant 2-bits as (11) representing Tag while the least significant 2-bits (01) represents the Line #1. This allows us to see that Line #1 in cache is actually holding contents of Block #13 of main memory, these contents being (52, 53, 54, 55) as seen in the video. Notice that Tag 11 is also found in Line# 3 (1111). Tag (11) Line# (11). I hope this helps.

@rammohan3876 8 лет назад

In the video what he expalined is corret... let me clear you. in line 1, 1,5,9 and 13 blocks can occupy. 13 the block words are 52,53,54,55. so his explanation is correct. he explained in this section in terms of word accessing. Hope this is clear :)

@ayahawari5242 8 лет назад

this is just a scenario... each line can get a tag either 00 or 01 or 10 or 11

@franciscomelojunior2535 7 лет назад

I was wrong, 1101: 13 block line, which are the numbers 52,53,54,55

@ibrar406 7 лет назад

he tells us the tag for line 1 is '11'. Why are you looking at tag for line 2, if were mapping for line 1?

@sachingaur7752 5 лет назад

I was impressed when I saw your video first time since then you're my ideal person. salute for your effort.

Sir I have one question how can be tag no 2 blocks are same ??? In this example two lines have same tag 11..

@subham5785 5 лет назад

This is just an example. You need not to put tags in in any sequential manner necessarily.

@pravip2716 6 лет назад

Sir,it made me to understand co well please upload more videos

@lexlee6625 6 лет назад

Quick question: Does the TAG refers to which memory block is in the cache line? For example, for the cache line at position 0 (the first cache line), memory blocks 0, 4, 8 and 12 are loaded inside. Thus they each take up position number 0, 1, 2 and 3 respectively. Hence, if the TAG is 10 (2 in decimal) , does this mean that only the memory block that is supposedly in the second position (memory block #8 in this case) is loaded into that cache line and the rest aren’t? Help is greatly appreciated thanks!

@mnitcse5523 8 лет назад

for block 4(in mm) = 0100 (block_no=> tag = 01 and line no. = 00 ) right so why block 4 is present in line no. 00 with tag 00 (in cache memory) ? observe that tags are different but line no. is same plz correct me at 20:55

Sir can you explain this lecture with no of blocks are 32 and the no.of lines=8 . I have a doubt in this .how will you take the tag value? Please anyone explain.

@mahendernaik653 6 лет назад

U have used two 11 , so when tag bit refers 11 then which is responded ? Does tag bit depends on line bits?

@hibaali7903 8 лет назад

thank. u 😍

@rajbrothers5113 9 лет назад

i didn't get whether the cache lines contain block no. or the words.and How the tag is assigned in the cache lines, is it random or depends upon the previous operations or else ?

@rajatrana2020 8 лет назад

Cache lines are just the replica of blocks in MM. They have the content of Block

@msaufy 7 лет назад

its the first example his say is wrong, if we refer to the example question the block in each line will be arrange sequentially, 0,1,2,3. not 0,4,8,12. right? means the cache will be never arrange to 0,4,8,12 in one cache line.
