PCIE is a layered protocol high speed interconnect interface supporting speeds up to 64GT/S and multi lanes and links. The layers specified in PCIE specification Transport, Datalink, Physical layers ...
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 ...
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 ...
