摘要： This invention relates to an information processing apparatus such as a digital signal processor and is applied particularly suitably to a digital filter.A plurality of data from initial value data till final value data relating to filtering coefficients of a digital filter are stored in a data memory, and are sequentially read out by an increment operation of an address arithmetic unit.A data arithmetic unit executes sequentially product and/or sum operations of a plurality of data that are sequentially read out and digital input signals that are sequentially inputted, to perform digital signal processing.The information processing apparatus is equipped particularly with means, which when an access address starts from an initial value, exceeds a final value and reaches a return address due to the increment operation, returns automatically the access address to the initial value. Therefore, a plurality of data stored in the data memory can be utilized repeatedly.Contrivances are made in order to set the number of a plurality of data that are stored in the data memory for repetition of use, to an arbitrary value.
