摘要：
This invention relates to a data processor with pipelining system, which is provided with at least two stages having working stackpointer respectively, and so constructed that each stage can independently refer to the working stackpointer corresponding to each stage, and each working stackpointer corresponding to each stage is renewed synchronizing with pipelining processing, so that when execution of a plural instructions including designation of operands under stack-push addressing mode and stack-pop addressing mode, result of address calculation executed at the address calculation stage is sequentially transferred to corresponding working stackpointers synchronizing with the transfer of instructions through the stages of pipeline, thereby being possible for the data processor to smoothly execute pipelining process.
