The invention provides a configurable digital filter device, and includes an instruction controller, a filter coefficient multiplexing module, a sampling data input module, a data engine module and an arithmetic module. The instruction controller is connected with the data engine module and the arithmetic module, the data engine module is connected to the arithmetic module and used for providing a filter coefficient and sampling data to the arithmetic module, the filter coefficient multiplexing module is connected with the data engine module, and a sampling data input module is connected with the data engine module. The device can share the data engine module and the arithmetic module, can perform instruction control on the data engine module and the arithmetic module, and enables the arithmetic module to complete multiplication and addition operation in a unified manner, different types of filters can be realized, a universal function is realized, multiplexing between different modes can be satisfied, a circuit delay can be shortened, and operation efficiency is improved.
