ABSTRACT:
A plurality of setting data stored in a serial register 11 and externally supplied replacement data are inputted into selectors 12. Either of the setting or replacement data is provided to the respective one of the setting inputs S.sub.1 -S.sub.n in a digital signal processing unit 10. Each of the selectors 12 usually selects the setting data. When a selector 12 is specified by a decoder 13 based on address data, it only selects the replacement data. When the replacement and address data are suitably set, the computation condition of the digital signal processing unit 10 can be partially changed without rewriting of the setting data in the serial register 11.
