<p>PROBLEM TO BE SOLVED: To provide the data processor of small heat generation or a small temperature fluctuation width capable of a high speed data processing arithmetic operation. SOLUTION: Plural processors capable of low power consumption mode control are used as parallel processors and slave processors 311, 321, 331 and 341 capable of the low power consumption mode control are controlled to a low power consumption mode when a data processing arithmetic operation is not required. When the data arithmetic operation is required, the slave processors 311 or the like are separately controlled to the low power consumption mode when the respective slave processors 311, 321, 331 and 341 do not perform the arithmetic operation and the time when the slave processors perform an arithmetic operation redundantly with each other is reduced. Thus, absolute heat generation is reduced.</p> |
