Abstract: There are provided an arithmetic unit and a receiver unit which execute an arithmetic operation at a high speed and allow reduction of the size thereof. An input section inputs data of the data group. First to n-th (n>1) storage sections have a capacity capable of storing at least part or all of the data group. A readout section selects one of the first to n-th storage sections and reads out therefrom a data group already stored therein. An arithmetic section performs a predetermined arithmetic operation between the data group read out by the readout section and the data group newly inputted by the input section. A writing section writes a result of the predetermined arithmetic operation by the arithmetic section in a predetermined one of the storage sections, which is not selected by the reading section as the one from which the data group already stored therein is to be read out.
