<p><P>PROBLEM TO BE SOLVED: To provide an information processor in which a circuit scale is smaller and more inexpensive, circuit design is easier and correspondence to specification change or the like of an applied product is more easily than those of an information processor of the conventional microcomputer configuration comprising a CPU and a ROM, and to provide its circuit design method. <P>SOLUTION: IN the information processor 100 formed on one semiconductor chip 1, a central processing circuit 40 for operating/adding data and controlling peripheral equipment 30a to 30c provided in a peripheral circuit 30 includes: a core sequencer 41 for executing prescribed instructions in a prescribed sequence; an ALU 14 for performing arithmetic and logical arithmetic processing; a status register 15 for storing flags being processing states of the ALU 14; and a general purpose register 16 to be used as a buffer when an instruction is executed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
