Embodiments of this application disclose a data processing apparatus and method, and a related device. Storage space of a second device is mapped to a memory-mapped input/output MMIO address space of the first device. N MMIO addresses in the MMIO address space of the first device are in a one-to-one correspondence with N first storage addresses in the storage space of the second device. The processor is configured to send a first instruction to the storage controller, where the first instruction includes a target MMIO address. The storage controller is configured to: receive the first instruction, and determine a first storage address corresponding to the target MMIO address; and send a first operation instruction to the second device, where the first operation instruction corresponds to the first instruction, and the first operation instruction includes the first storage address.

Apparatus for a first device MMIO mapped with a second device and a method of performing data processing operations therebetween

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.

Operation accelerator, switch, task scheduling method, and processing system

Embodiments of the present invention provide a method and an apparatus for storing data, which relate to the field of data processing. In the present invention, a current device is divided into different load modes in the process of service processing, and manners of storing various data in a Cache are dynamically adjusted, so that nodes with different characteristics in the current device may control operations on the Cache, thus achieving lower power consumption and optimum performance of a large-capacity system under a heavy load.
