PCI-SIG® built upon our momentum from 2020 with another successful year in 2021. From progress on the PCIe 5.0 architecture compliance program to the impending release of the PCIe 6.0 specification, we have hit many exciting milestones.

The upcoming PCIe® 6.0 specification introduces Flow Control Unit (FLIT) encoding, which enables the specification to provide low latency with high efficiency. FLIT mode is adopted for the PCIe 6.0 architecture because error correction needs to operate on fixed sized packets.
