Abstract
PURPOSE:To realize easy simulation for various types of input/output devices, by providing a storage part where the information defining the input/output action to a virtual input/output device is stored, a setting part of an abnormal state and an executing part where the contents are executed for both the storage part and the executing part. CONSTITUTION:When a new input/output device is developed, the action defining firmware of the input/output device is loaded to a control information storage part 204 at the storage part of a virtual input/output device controller 102 from a prescribed external storage part. At an executing part 203, the setting contents of an abnormal state setting part 202 are read every time the virtual input/output is executed based on the information of the part 204, and the virtual input/output is completed with an abnormal state if an abnormal state is indicated on a channel during process. At the same time, the queuing information of an external storage device 103 is stored in the part 204 for each device to guarantee the data. And the device position of the end of an input/output request is stored in a present position storage region 205 at the storage part. At the part 203, an input/output end signal is transmitted to an input/output controller 101 through a requested channel 104 when a series of virtual input/output actions are over.
