Abstract: Examples in this application disclose an operation accelerator, a switch, and a processing system. One example operation accelerator includes a shunt circuit directly connected to a first peripheral component interconnect express (PCIe) device through a PCIe link. The shunt circuit is configured to receive first data sent by the first PCIe device through the PCIe link, and transmit the first data through an internal bus. A first address carried in the first data is located in a first range. In some examples of this application, the first PCIe device directly communicates with the operation accelerator through the shunt circuit in the operation accelerator.

Abstract: Embodiments of this application provide a method and apparatus for wired data transmission. The method is applied at a first end, data transmission is performed between the first end and a second end over a first data link, and the first data link is a serial data link or a parallel data link. The method includes: receiving a second rate range sent by the second end, where the second rate range belongs to a transmission rate range supported when the second end receives data over the first data link; sending a second training bitstream to the second end, where a first rate belongs to the second rate range; and sending the data to the second end at the first rate over the first data link. Embodiments are implemented, to change a transmission rate of a data link in a rate range, and reduce a communication resource waste.
