ABSTRACT:
A compact and small compensating-electric-power data processor is realized by dividing a plurality of calculations to be carried out by a complex instruction into a number of executing units to be processed, instead of executing the calculations in parallel as in the past. For this purpose there is provided a decoder having a detecting part for decoding an instruction and for detecting whether the instruction is an instruction for executing a plurality of calculations, a field rearranging part for rearranging a part of the fields of said instruction based on a predetermined number of calculations to be processed if it is judged by said detecting part that the instruction is an instruction for executing a plurality of calculations, and a calculation control part for performing control to execute the calculations in plural cycles in synchronism with the order of said rearranged fields. A calculation part operates to execute the calculations called for by dividing the instruction into plural cycles based on control from the calculation control part.
