Mapping of system memory in PCIe end point device
Configuration space of end point devices and bridge devices
NO. of memory/ IO region defined
IO region can be mapped into 16/32 system address space
Memory region are mapped in 32/64 bit system address space

PCIe Architecture: Lecture-1
มุมมอง 150K5 ปีที่แล้ว
This video explains the following in the PCIe Protocols Introduction to PCIe Protocols Concepts like lane, link, initialization, differential signal, throughput. PCIe Topology, various components ( Root Complex, End Point ( Legacy End point, Native End Point), Switch etc. PCIe architecture in terms of logical layers. Three layers ( transaction layer, link layer and Physical layer). Task of each...
Hi Sir, Can we get the notes for the lecture
Could you please explain LTSSM as well ?
Can you please provide subtitles? (CC)
Thanks for the explanation, will appreciate if you could share the Link to the Notes used in the Video.
Pls upload more.

Short and helpful.
Hello Sir Could you please tell me Architecture diagram of PCIe to Memory (P2M) for Read...?
Very helpful lectures sir. ❤
PCIe nicely explained for beginners... Thanks so much.
hi, please correct me if I am wrong. During initialization, all connected Devices are assigned some address spaces from System Memory. And devices keep this info of memory space at their specific PCIe Configuration Space. Whenever a PCIe configuration cycle is generated, they monitor their dedicated adress block. Is it how it works? If it is so, how is that pCIe configuration cycle generated? thanks
hi, at 29.49, you say that data length (10 bits) can be up to 4096 Byte. But you can identify only up to 1024 byte with 10 bits. Am i wrong? thanks in advance.
Thank so much !
@PCIe sir, can we get the notes as well? btw, I am indebted to your for this valuable content delivery that too on free platform like youtube. thanks a lot. :)
Hi, Please share all the lectures Notes
Thank you, very helpful
how 1k word becomes 4kbtes @ 6:20
Generally a word is considered to be 4 Bytes. So 1K Words becomes 1024x4= 4096 Bytes . The definition of word size may vary
@@testbenchmakerthankyou. Means word size may vary, noted!
Whether CPU always go through Address port OxCF8 and Data port OxCFC for CAM; or this address will vary w.r.t PCIe gen? OxCF8 means Bus0 Device3 one function and register number is 0x37, OxCFC for data port can b read or write operation @pci3823
Grt explanation sir, thank you so much, if you can attach the slides or pdf which you were explaining would be helpful for us
At time 22:30 it is 2p24 - 2p4 = 2p20=1MB not 16 mb as ur saying.
I have doubt like after primary secondary and subordinate when bus device and function come into picture and when we will represent function with 1 and when will device numbers change in one branch device number is completely zero in other branch device number changes
Very good explanation in detail. Covered all sides of pcie
Please help with that
Need some testcases on this
Thanks Sir
Thanks
Great sir
Very good explanation, very helpful thank you
good explanation👍
Quality explaination 👍
Quality presination, as Naveen commented below, i have paid for PCIe training online and this is better.👍
Root complex
x12 not supported by pcie
Can I please have your notes as a document for all 4 videos? I will help a lot.🙂
great work, much appreciated. You should definitely post more LECTURES
at 13:26 you are saying that if (ENDPOINT) EP3 has to communicate with EP2, it will go through switch. But I believe that both EPs CAN'T communicate like this, there should be proper transaction from RC(root complex) via core. If any communication has to happen between two EPs then 1st EP will write on certain MEMORY and other EP will read from that. Please correct me if I am wrong. Thanks
Thank You for this lecture.
Thank you. it great explanation
Thanks for taking time in going into such detail about BAR programming. Encourage you to contribute more such content
Best explanation till now seen simple to complex clearly explained.. thanks so much
15:56 16MB not 8MB
In PCIe Version 1 on a x1 configuration, the maximum data transfer rate is 160 Gbps (2.5GT/s), but only 2 Gbps (250 MB/s) is encoded serial data?
In a single lane, how fast is the data speed? Can the Tx and Rx channels transmit data simultaneously at 2.5 GT/s? Or is the maximum transfer speed only capable on a single channel, Tx or Rx at a given time?
Please sir make a video on PCIe ltssm States
Can you share this PDF as quick reference
Hi sir, does PCIe support daisy chain configuration
Very Informative, thanks!!
Thank you very much .....
Thank you for posting😊
Thanks Mr. Lovekesh for taking initiative to pass on the knowledge and saving lot of our time and keeping our attention focused during this entire Part.1 video of PCIe. It was very good start for us and to gain enough confidence to start deep diving.
