Non Posted Transactions

Hi guys, I’m a beginner with the PCI Express and I have a simple question.

Does the DMA/Bridge Subsystem for PCI Express supports non-posted transactions or only the 7 Series Integrated Block for PCI Express does?

Please help me, this issue makes me confused.

Thanks a lot.

Hi, 

The DMA/Bridge Subsystem for PCI Express product guide mentions non-posted request here under Target Bridge: https://www.xilinx.com/support/documentation/ip_documentation/xdma/v4_1/pg195-pcie-dma.pdf#page=14

It also talks about TLP in general and more in depth here: https://www.xilinx.com/support/documentation/ip_documentation/xdma/v4_1/pg195-pcie-dma.pdf#page=108

I hope that helps!

Ebrahim

hi @iskander555 

 

the DMA/Bridge Subsystem IP includes Integrated Block IP. i.e., Integrated Block IP is part of DMA/Bridge Subsystem IP.

 

Both IP can support non-post transactions or requests.

 

Thanks,

Boris
