ABSTRACT:
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.
