Abstract:
An information processing system comprising:a plurality of input/output devices each having a plurality of input/output terminals; a plurality of processors; and a device controller, provided between said input/output devices and said processors, for storing mapping data defining a mapping of said input/output devices and said input/output terminals to said processors and state data indicating states of said input/output devices, said terminals, and said processors, and for controlling transfer of transmit/receive information from said input/output devices and said input/output terminals to said processors and vice versa by referring to said mapping data and said state data; wherein said device controller includes: a processor state management unit for storing processor state data in a memory for management; an input/output device state management unit for storing input/output device state data and input/output terminal state data in a memory for management; and a controlling processor management unit for storing said mapping data of said input/output devices and said input/output terminals to said processors in a memory for management; and wherein said device controller further includes a data change controller for changing said mapping data by referring to said state data.
