PURPOSE:To improve the performance of a data processing, by re-allocating a task in which instruction exception is generated on a processor added with a dedicated processor by a processor allocation means. CONSTITUTION:Task schedule allocating the processors 10 and 11 in which the load of a multi-processor system can be distributed is performed, and when an instruction for the dedicated processor 20 is issued on the processor 11 on which no dedicated processor 20 is added under execution of a task, the processor 11 generates the instruction exception. And the processor 11 by which the instruction exception is generated is detected by an instruction exception generating processor detecting means 61, and the processor 10 on which the dedicated processor 20 is added is selected by a processor information retrieval means 62, and the task generating the instruction exception is re-allocated on the processor on which the dedicated processor 20 is added by a processor allocating means 63. Thereby, it is possible to distribute the load and to improve the performance of a system.
