Abstract
PURPOSE:To speed up a processing by limiting the input of zero data to an arithmetic part and omitting a vector operation by the zero data when the zero data are detected by a zero detecting part. CONSTITUTION:When the zero data are detected by a zero detecting circuit 9, the appearing pattern of the zero data is transmitted to an arithmetic part control circuit 14 through an input part control circuit 10. By the zero pattern, the arithmetic part control circuit 14 knows, for example, at which point of time data to be set to a memory 7 for input data should be canceled, does not set the data of the memory 7 at the point of time and sets the data in, for example, a memory 6 for the input data to store next data. Thus, a wasteful operation for one cycle can be omitted and improve the efficiency of the processing.
