PCIe peer-to-peer communication (P2P) is a PCIe feature which enables two PCIe devices to directly transfer data between each other without using host RAM as a temporary storage. The latest version of Alveo PCIe platforms support P2P feature via PCIe Resizeable BAR Capability. Data can be dire...
The system includes a first processor configured to initiate a communication arrangement between a first peripheral component interconnect express (PCIe) device and a second PCIe device. The communication arrangement is configured to detect transfers from the first PCIe device to one or more addresses ...
PCIe peer-to-peer communication (P2P) is a PCIe feature which enables two PCIe devices to directly transfer data between each other without using host RAM as a temporary storage. However, there are a number of issues that make P2P transactions tricky to do in a perfectly safe way. One of...

Hi, we are trying to achieve communication between two endpoint FPGAs. The architecture of the system is as follows: PC (root complex) | pcie switch
Graphics applications typically use x16-width links. Peer-to-peer communication is supported in switch hardware, allowing the shortest possible path between the peers. As with the fanout switch, the links can be at any supported PCle speed, for any supported width. ...
We are trying to make a peer-to- peer transaction between 2 End-Points, through Intel chipset without succession. (Not through CPU/ CPU memory). The 2 E.P. connected to PCIe channels of the QM57 \ QM77 \ QM170. There is communication between the EP and the CPU/CPU memory. but not...
Features such as low-latency, low-power fully compliant to PCIe Specification 3.0, 2.0 and 1.0, all enable high-speed serial point-to-point connections between multiple I/O devices and a root complex or microprocessor for optimized aggregation, fan-out or peer-to-peer communication of end-point...
