<P>PROBLEM TO BE SOLVED: To provide an information arithmetic operation device capable of executing processing at a high speed. <P>SOLUTION: A CPU reads command information of a program composed of a predetermined processing signal in an IF stage in a command register 153B from a main storage means 120. An ALU 155 returns an arithmetic operation result to a memory data register 153C by directly arithmetically processing the command information of the command register 153B. Thus, the CPU can omit processing for decoding the program by directly processing the command information of the program, and can improve throughput of the CPU by shortening execution time for processing one command information. <P>COPYRIGHT: (C)2007,JPO&INPIT |
