A data processing device having a pipeline bypass function passes an operation result of a preceding instruction to a succeeding instruction as a source operand before writing the operation result to a register. A source operand bypass specification field and a source operand register field in the instruction code are provided to control passing of the operation result. A source operand selector responds to the source operand bypass specification field by selecting data either from the register or the bypasses as a pipeline input data. |
