Waiting for PCIe Gen4 and its 16Gtransfers/sec/lane to be real? Wait over. IBM and Xilinx achieve Gen4 interoperability

Today, IBM and Xilinx announced PCIe Gen4 16/Gtransfer/sec/lane interoperation between an IBM Power9 processor and a Xilinx UltraScale+ All Programmable device. (FYI: That’s double the performance of a PCIe Gen3 connection.) IBM expects this sort of interface to be particularly important in the data center for high-speed, processor-to-accelerator communications, but the history of PCIe evolution clearly suggests that PCIe Gen4 is destined for wide industry adoption across many markets—just like PCIe generations 1 through 3. The thirst for bit rate exists everywhere, in every high-performance design.

 

All Xilinx Virtex UltraScale+ FPGAs, many Zynq UltraScale+ MPSoCs, and some Kintex UltraScale+ FPGAs incorporate one or more PCIe Gen3/4 hardened, integrated blocks, which can operate as PCIe Gen4 x8 or Gen3 x16 Endpoints or Roots. In addition, all UltraScale+ MGT transceivers (except the PS-GTR transceivers in Zynq UltraScale+ MPSoCs) support the data rates required for PCIe Gen3 and Gen4 interfaces. (See “DS890: UltraScale Architecture and Product Data Sheet: Overview” and “WP458: Leveraging UltraScale Architecture Transceivers for High-Speed Serial I/O Connectivity” for more information.)
