Abstract: This application relates to similarity calculation apparatuses and methods, and storage devices. An example similarity calculation apparatus includes an input signal processing circuit, a data calculator, and at least one output processing circuit, where the data calculator includes a storage array configured to store to-be-calculated data. The input signal processing circuit is configured to: generate an operating voltage based on similarity calculation instructions, and convert an address of the to-be-calculated data in the similarity calculation instructions into a target address The data calculator is configured to: select, based on the target address, the to-be-calculated data stored in the storage array, and apply the operating voltage to the to-be-calculated data to perform similarity calculation. The at least one output processing circuit is configured to: process a signal output by the data calculator, and output a calculation result.
