    • A fault recovering method for substituting an instruction processor (IP) for a system supporting processor to execute processing thereof when the system supporting processor fails. An apparatus implementing this processing method comprises a plurality of processors, at least one of which is operated as a system supporting processor (SSP) and the rest of which are operated as instruction processors. When the SSP fails, an interrupt is generated to an OS running on at least one IP. The OS recognizes that a fault occurred in the IP, abnormally terminates an application program which has been running on the IP when the interrupt was generated, or stops instruction processing as the IP falling into a hardware failure state, or input a command for disconnecting an alternate instruction processor for the system supporting processor, so that the IP takes over functions of the SSP.
    • 一种在系统支持处理器发生故障时用于替代系统支持处理器执行处理的指令处理器(IP)的故障恢复方法。 实现该处理方法的装置包括多个处理器,其中至少一个作为系统支持处理器(SSP)运行,其余的处理器作为指令处理器运行。 当SSP发生故障时,会对运行至少一个IP的操作系统产生一个中断。 OS认识到IP发生故障,异常终止在产生中断时已经在IP上运行的应用程序,或者当IP落入硬件故障状态时停止指令处理,或者输入断开连接的命令 用于系统支持处理器的交替指令处理器,使IP接管SSP的功能。
