    • A data processor includes a register group having registers of the number larger than the number of registers which can be designated by a register specifier field of an instruction. The register group consists of a plurality of register queues with respect to logical register numbers designated in the instruction, each register queue including a plurality of physical registers. In the data processor, a physical register number forming section is provided for converting the logical register number to a physical register number in the register queue corresponding to the logical register number, by using queue control information designated in the register specifier field and read/write information decided by the kind of the instruction and the position of the register specifier field in the instruction.
    • 数据处理器包括具有比可由指令的寄存器说明符字段指定的寄存器数量大的寄存器的寄存器组。 寄存器组包括相对于指令中指定的逻辑寄存器号的多个寄存器队列,每个寄存器队列包括多个物理寄存器。 在数据处理器中,提供物理寄存器号码形成部分,用于通过使用寄存器说​​明符字段中指定的队列控制信息和读取/写入将逻辑寄存器号码转换为对应于逻辑寄存器号码的寄存器队列中的物理寄存器号码 指令种类决定的信息和指令中寄存器说明符字段的位置。
