    • An information processing apparatus includes an instruction storage for storing a plurality of instructions and a central processing unit for fetching the instructions from the instruction storage device so as to execute the instructions. The central processing unit executes a process to perform operations which require at least two machine cycles of the central processing unit by separately executing a first instruction for setting first data required for operations and a second instruction for fetching second data obtained by the operations. The machine cycle is a time unit for executing an instruction by the central processing unit. The central processing unit executes at least one third instruction after executing the first instruction and before executing the second instruction, the third instruction not requiring the second data.
    • 信息处理装置包括用于存储多个指令的指令存储器和用于从指令存储装置取出指令以执行指令的中央处理单元。 中央处理单元执行执行需要中央处理单元的至少两个机器周期的操作的处理,该操作分别执行用于设置操作所需的第一数据的第一指令和用于获取通过操作获得的第二数据的第二指令。 机器周期是用于执行中央处理单元的指令的时间单元。 中央处理单元在执行第一指令之后并在执行第二指令之前执行至少一个第三指令,第三指令不需要第二数据。
