PURPOSE:To facilitate fault process evaluation by generating a dummy fault in response to common memory access from a specific processor by a memory access controller to which plural processors can be connected without limiting the constitution of processor connections. CONSTITUTION:The memory access controller 101 to which the processors 1031-103n can be connected consists of a device specifying means 114 which specifies the number of a processor which issues a common memory access request for which the dummy fault is generated, a comparing means 116 which compares the number of a request source processor added to the common memory access being processed with the output of the device specifying means 114, and a means 118 which makes the dummy fault effective when the comparison result shows that the device number is coincident; and the dummy fault is generated only for the common memory access issued by the specific processor. |
