When the data stored in the memory 1 is read, the compressed coefficient from the memory 2 and compression information are read and the data is expanded via a data expansion circuit 3 by the read compression information. Then the data after expansion and the compressed coefficient are fed to an accumulation multiplier 4, where the data after expansion and the compressed coefficient are subject to accumulation multiplication as a true value at the multiplier 4 so as to apply the accumulation multiplication with the coefficient before compression as to the data. Thus, the operating speed is quickened and the processing capability is improved.
