ABSTRACT:
A processor includes a source register having a source register content, a destination register, a calculating unit for performing a calculation using the source register content, wherein the calculation is performed in several calculation cycles, and wherein in each cycle only one portion of the source register content is useable, a data bus connected to the source register, the destination register and the calculating unit, and a processor controller. The processor controller is operable to supply the source register content in portions to the calculating unit on the one hand and to the destination register on the other hand during the calculation via the data bus, so that after an execution of the calculation the source register content is written into the destination register. Therefore it is possible to obtain a register copy of a source register the destination register via a limited data bus without additional machine cycles for long operands to be processed in portions.
