Apparatus and method for executing an instruction with a register bit mask for transferring data between a plurality of registers and memory inside a processor

摘要

An apparatus and method for executing an instruction with a register bit mask for transferring data between a plurality of registers and memory inside a processor is provided. The method includes adding the N bits in the N-bit decode information together to form an initial count value, and generating a plurality of register identification (ID) numbers equivalent in number to the initial count value. The register ID numbers correspond to the positions in the N-bit decode information that has a bit value '1'. According to the register ID number, a link is created between the plurality of registers corresponding to the register ID numbers and a memory unit so that the memory unit and the registers are free to exchange stored data.
