Direct Memory Mapping – Solved Examples

Thank you sir❤

i dont know why but the concepts are not clear might be too much vagueness is there..i have been watching neso for a long time now but only this time i m left with the doubts.

Awesome video and teacher. Thank you so much for these easy-to-understand videos.
There's one thing I haven't understood, isn't 1Kb the same as 1000 bytes, and not 1024 like in your examples? I thought 1Kib was 1024 bytes

Consider a main memory of the size 64 kB with each word being of 8 bits (one byte) only and a direct mapping Cache memory of size 4 kB also having data word size of 8 bits. Find the following :

(i) What is the size of tag and index fields of cache ?
(ii) In what location of Cache, hexadecimal address to main memory (AABB) (if exists in cache) will be located ?

what's answer of this question, can anyone tell..?

Amazing🙏

so tag bits represent the log(times the cache would fit in the ram). if ram is 4 times the cache size, then the tag bits are 2. in above case, 2^10 times x cache size = ram size. therefore. cache size is ram size/2^10= 16 x 2^10 x 2^10 x 2^10 bytes. = 16 MB.

Screw it. Im'm going to fail

Thanks for the video sir ....

WORD is 1 or 2 Bytes?

Thank you, You all are really blessed. Thank you, one thousand times Thank You.

example 3: 10 tag bits..... So 2*34/2^10 = 2^24 =16MB. no need other info i think

I didn't get the concept of tag directory. Can anyone help me out?

Thanks for covering every kind of questions 🙂🙂🙂🙂❤️❤️❤️❤️🙂🙂🙂🙂

Bow down 🙇🏻‍♂️ to him ❤

MM size = 4GB =2^2*2^30Bytes=2^32bytes=2^32*2^3bits=2^35 bits right?

You're too quick, slow down

disliked because of cringe voice. taking lecture at 3 in night for exam at 8 and this boy sound so cheerful

Very informative and amazing lecture. Can you please suggest a good book also for computer architecture and to solve more numerical based problems like this

where can i find your course ppt or pdf ? can you share it? thanks

You saved me, LOVE YOU ❤️

Wow, this is an amazing lecture... far better than the three 1h 30m lectures that my professor gives. Once I start my career, I can't wait to donate to this channel. It's been SUCH a lifesaver for me!

hates off

fabulous!! very clearly understood in less time!! thank you neso!!

Hey! I noticed one thing that size of cache is equal to the no. of blocks in MM. Is this true for every computer?

This playlist is progressing too slow.If possible please fast a little bit.

Great explanation in just 10mins.
keep it up.
I recommended this lecture series to my children's XD

👍

Please complete lecture video on Compiler design plsss sir really need

❤️

Right on time for my exams

First viewer.. 👍🏾
