摘要： The interrupt level storing unit (16) stores one or more interrupt levels indicating the priority of a generated interrupt and stores the interrupt level having the highest priority among the stored interrupt levels as a second interrupt mask level. The second interrupt type determination unit (13) sets an interrupt level corresponding to the interrupt type of a newly generated interrupt. The priority determination unit (14) notifies the interrupt to the virtual machine control unit (20) when the interrupt level of the newly generated interrupt is higher than the stored second interrupt mask level. As a result, the priority of the virtual machine can be determined according to the task priority and the switching of virtual machines can be adequately controlled even if the virtual machines cannot notify the task priority.
摘要翻译：中断级存储单元（16）存储一个或多个指示生成的中断的优先级的中断级别，并将存储的中断级别中具有最高优先级的中断级别存储为第二中断屏蔽级别。第二中断类型确定单元（13）设置与新产生的中断的中断类型对应的中断级别。当新产生的中断的中断电平高于存储的第二中断屏蔽电平时，优先级确定单元（14）向虚拟机控制单元（20）通知中断。结果，可以根据任务优先级来确定虚拟机的优先级，即使虚拟机不能通知任务优先级，也可以适当地控制虚拟机的切换。
