Abstract: A resource scheduling method, to improve resource utilization of a field-programmable gate array (FPGA) device, includes receiving a resource scheduling request from a host, where the resource scheduling request requests to schedule a partial region (PR) on the FPGA device to serve a first virtual device (VD) of the host, the FPGA device includes N PRs, the host includes M VDs, each of the M VDs is configured corresponding to one virtual machine (VM), the first VD is one of the M VDs, and both N and M are integers greater than one, obtaining context content of the first VD based on the resource scheduling request, determining a target PR in the N PRs, and deploying the context content of the first VD in the target PR.

Abstract: A data writing method includes obtaining first to-be-written data, where the first to-be-written data is data to be written into a first memory in the processing system; determining a first codeword length based on a first redundancy ratio corresponding to the first memory; performing ECC encoding on the first to-be-written data based on the first codeword length, to obtain first redundant data, where the first redundancy ratio is equal to a ratio of a data bit included in the first to-be-written data to a redundant bit included in the first redundant data; obtaining a memory type of the first memory; and writing the first to-be-written data and the first redundant data into the first memory based on the memory type.
