PURPOSE:To execute a high speed host interruption processing by providing a holding means to combine a new program with the exceptional contents of a host CAT at the time of a guest interruption processing in a virtual computer to execute duplicate address transformation (DAT). CONSTITUTION:In a DAT where the actual address of a guest corresponds to the virtual address of a host, when the exception of a host DAT is detected during a guest interrupting processing, the state is immediately transitted to a host interruption by a state transition means 1. Then, a holding means 22 to combine the new program with the exceptional contents provided in a virtual computer is referred and the host interruption is executed by a processing means 3. Thus, the high speed host program interruption processing for the host DAT is executed without an emulation by a firmware. |
