PROBLEM TO BE SOLVED: To accurately control a waiting time when making a main operation part of a CPU (central processing unit) or the like wait execution of processing by an instruction. SOLUTION: This information processor has: the main operation part performing the processing according to an instruction read from a memory; and an expansion operation part performing processing according to a prescribed instruction of the instructions read from the memory. The expansion operation part has a signal generation circuit counting a pulse of a clock signal, and outputting a signal showing that it has to wait when the instruction read from the memory is the wait instruction making the main operation part wait until a count corresponding to a wait count number designated in the wait instruction is completed. The main operation part stops the processing while the signal showing that it has to wait is output. COPYRIGHT: (C)2009,JPO&INPIT
