I saw this video 10 minutes before the start of the exam ( microprocessor) ...The paper asked to explain DMA for 4 marks...I wrote exactly the same in the paper as explained here and i got 3 marks for the answer...

[@saravanan_asb]

So sad...Not 4 marks 😢

[@Rahulkumar-dg5pu]

Perfectly Explained, I did not have any notes for DMA and saw your video outside the exam hall... wrote what you explained and drew the same diagram and got 4 out of 5 :)))

[@bhopenkhuman4995]

best explaination. It is good for people like me who is not good in hindi. Thank you that you have used english as a medium

[@MajinErick]

Now that we move to NVMe, this way of i/o might just bottleneck SSDs because of the buffers that were probably designed for older ATA

[@rokeshnaidu9786]

Sound slow ga undi sir but super telling Tq sir🤝🤝👨‍💻

[@anujgajbhiye3765]

How is the problem of IO cycles solved here? Is it the data which is fetched from drive into disk controller related to IO ?

[@siddharthmagadum16]

what does "goes to" mean here? Does it mean that data is transferred to CPU, then memory?

[@hehehehehe1878]

Ig "goes to" here means that the i/o device first requests the CPU to get access to the memory inorder to share or retrieve information.

[@nikhilsinghmahar3356]

I can't find Rest Of the videos for DMA

[@kaushikgopu9482]

Can u please explain about interrupts

[@pratikyalameli4450]

Sir, you rock You're man kind angel😁

[@yanxiaosun4363]

Just like setting up a middle man to do the control. But don't the interrupt, control, request, ack count as the cycle we're trying to eliminate?

DMA is not interesting for a few bytes. It becomes interesting for a few thousands ;-)

[@AhamedKabeer-wn1jb]

Superbly explained...

[@ShrenikJain]

+vikas pande Thanks 😃

[@shubhshree5419]

clear explaination

[@balanaguharshavardhan3725]

but isnt it like having a mini-cpu??and can acknowledgment be considered as a cycle??

[@ShrenikJain]

anony _me I/o lacked control signals therefore it needs CPU to perform Operation. But hai if you can give I/o control signals it will not require CPU .. Therefore we have Dma which gives control signals to I/o and rest is video 😀

[@santoelectron]

- Something that wasn't explained was the counter. How can you tell the data size required to fill the memory? CPU does it? What about if the CPU does know the size of the data that would be getting from the disk? Or maybe, do you set the DMA register to tell the size of data that should be getting from the disk? - Does it mean DMA does not have a buffer?

[@shreyasrai]

HI What is the usecase/example explained in the 1:04? What I/O device directly communicates with DMA controller? I

[@goncalosousa9691]

Can DMA interact with CPU?

[@hehehehehe1878]

DMA requests CPU to handover the bus control to it so that DMA can function on it's own.
