Abstract: The present disclosure relates to a data ranking apparatus that comprises: a register group for storing K pieces of temporarily ranked maximum or minimum data in a data ranking process, the register group comprises a plurality of registers connected in parallel, and two adjacent registers unidirectionally transmit data from a low level to a high level; a comparator group, which comprises a plurality of comparators connected to the registers on a one-to-one basis, compares the size relationship among a plurality of pieces of input data, and outputs the data of larger or smaller value to the corresponding registers; and a control circuit generating a plurality of flag bits applying to the registers, wherein the flag bits are used to judge whether the registers receive data transmitted from corresponding comparators or lower-level registers, and judge whether the registers transmit data to high level registers.
