A sum-of-products arithmetic unit includes a coefficient register, a data register, a multiplier, an adder, and a data bus used for the transfer of data to and from an external unit. Provision is made to allow addresses in the data register in which sum-of-products arithmetic data is to be stored to be specified without externally specifying an individual address in the data register for each piece of arithmetic data. This provision comprises an automatic data batch storage section, automatic address setting section, or address setting section.
