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.

The PCI Express^® (PCIe^®) 6.0 specification will provide multiple features, including Transaction Layer Packet (TLP) payload, encoding and decoding, shared credit pooling, Forward Error Correction (FEC), CRC error correction, and more.
