摘要： An FIR filter-based filtering method and apparatus, a system, and a storage medium are provided. The FIR filter-based filtering method includes: acquiring (S11) a preset filtering order and a preset down-sampling multiple; selecting (S12), according to the preset down-sampling multiple, a corresponding number of filter multiplexing units, and using each of the selected filter multiplexing units as a used filter multiplexing unit, wherein the FIR filter includes multiple filter multiplexing units; configuring (S13), according to the preset filtering order, a filtering order for each used filter multiplexing unit; filtering (S14), according to the preset down-sampling multiple, input data allocated to each used filter multiplexing unit through the each used filter multiplexing unit configured with the filtering order, to obtain unit filtered data outputted by the each used filter multiplexing unit; and merging (S15) the unit filtered data respectively outputted by the corresponding number of used filter multiplexing units and outputting merged unit filtered data.
