PROBLEM TO BE SOLVED: To copy plural pieces of operation data controlling an operation of digital signal processing by simple and high-speed processing without labors.SOLUTION: A current memory and a snap shot memory each store a parameter value group and management information for managing a data configuration by a hierarchy structure comprising plural collections. The management information includes plural pieces of collection management information corresponding to the collections, respectively. The collection management information comprises configuration information including a slave node ID, and a collection ID unique to a configuration of the collection indicated by the configuration information. During a snap shot recall, the collection IDs are sequentially compared from an upper collection, and the coincident collection is overwrite-copied as it is (S2), and the non-coincident collection is not overwrite-copied and a lower collection is set as a new processing object (S3). |
