XpressSWITCH is a customizable, multiport embedded Switch for PCIe designed for ASIC and FPGA implementations enabling the connection of one upstream port and multiple downstream ports and fully configurable. XpressSWITCH is the first embedded switch IP available on the market and enables designers to use fewer PCIe PHYs, saving latency, power consumption and bill-of-material.


  • 1 upstream port, up to 31 downstream ports Up to x16 link width per port Link rate of up to 16 Gbps
  • (PIPE) 4.x compliant , Single Virtual Channel (VC) implementation, AER, ECRC, ARI, Hotplug
  • Independent configuration of link width, link speed, equalization settings, and PIPE interface width per-PCIe port
  • Peer-to-peer, Broadcast and Multicast, Round-Robin arbitration,
  • No Packet buffering, Data Protection, Integrated Clock Domain Crossing

Device Utilization and Performance

The XpressSWITCH IP transparently manages upstream-downstream data flow as well as peer-to-peer transfers between downstream ports, delivering the flexibility, scalability and configurability required for connecting multiple devices, including NVMe SSDs.
