PURPOSE:To execute the processing smoothly at a high speed when the interruption occurs at the virtual computer by transferring a stack, obtaining the address of the interruption handler of the object virtual computer by a vector table and shifting the control, when the interruption is detected by a discriminating device. CONSTITUTION:When some requests are executed from a computer VM (2-1-2-n), the control is shifted through a VM supporting function 5 realized on the hardware to a virtual computer control program VMCP1-1. The program VMCP1-1 sets the discrimination whether the interruption is executed or not, to a hard register 20, starting is controlled by the starting control function 5-1 of the computer VM provided in the function 5, and in case of interruption, the control is shifted to an interruption handler and except it, the control is shifted to the next instruction of the computer VM. Thus, the interruption processing can be executed at a high speed and smoothly.
