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.
