PURPOSE:To utilize an arithmetic capacity by executing a conversion of a radix format of each data by a decomposing circuit and a synthesizing circuit of the inside of an arithmetic unit. CONSTITUTION:Plural pieces of radix formats are set in advance, and a code signal for showing its radix format is added to input/output data. A conversion to a radix format of each data is executed by decomposing circuits 3, 4 and a synthesizing circuit 11 of the inside of an arithmetic unit. Accordingly, an operation of each different radix format can be executed, and also even of a result of operation becomes a value which cannot be expressed by an input format, it is possible to proceed to the next processing by changing the radix format. |
