Abstract

PURPOSE:To ensure the efficient study and countermeasure to a fault of a system, by coding the logical conflict inside a program or a hardware fault and displaying the environment and the code at a moment when the logical conflict or the hardware fault occurs. CONSTITUTION:When an SVC (Supervisor Call) instruction is executed, an SVC interruption is caused. The contents of a PSW register 4 is stored in the old PSW storing region of the SVC in a hardware fixing region 11 along with an interruption code. Then the contents of a new PSW storing region of the SVC in the region 11 is set at the register 4. The new PSW shows the head address of an SVC interruption handler. When the SVC interruption handler is executed, the factor of the interruption is examined. Then an SVC interruption process program corresponding to the code deciced by a lower byte of the SVD interruption is executed.
