A four lane link has eight times the data rate in each direction of a conventional bus. Lattice’s PCI Express Root Complex (RC) Lite core provides an x1 or x4 root complex solution from the electrical ...

PCIe Gen1 and Gen2 use 8/10 bit encoding while PCIe Gen3 uses 128/130 bit encoding scheme. The maximum supported speed and link width depends on the application and use case of the SoC in which it is ...

Instead of having a bus with a common medium (traces) to which multiple devices connect, PCIe uses a root complex that directly connects to PCIe end points. This is similar to how Ethernet ...
