摘要

Embodiments of this application disclose an operation accelerator, a switch, and a processing system. The 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 the embodiments of this application, the first PCIe device directly communicates with the operation accelerator through the shunt circuit in the operation accelerator, to reduce transmission load of the PCIe link, and further avoid traffic congestion generated by the PCIe link.
