Abstract:
An information processing system comprising at least two different kinds of storage devices and an information processing unit having at least a first slot and a second slot for attaching each of the storage devices thereto individually, whereinsaid at least two different kinds of storage devices includes at least:a first storage device used by being inserted to said first slot to store data including at least one of program data, image data and audio data in digital form; anda second storage device, in which data is stored in a different way from said first storage device, used by being inserted to said second slot to store data including at least one of program data, image data and audio data in digital form,said information processing unit includes:a detector which detects whether said first storage device is attached to said first slot and whether said second storage device is attached to said second slot; anda processor which performs predetermined information processing on a basis of the program data stored in said first storage device or said second storage device which is inserted to said first slot or said second slot respectively when said detector detects that the first storage device or the second storage device is inserted to the first slot or the second slot respectively; andwhich processor starts the information processing on the basis of the program data stored in said first storage device when said detector detects that said first storage device is inserted to said first slot and that said second storage device is inserted to said second slot;wherein said first storage device includes a first responder which generates a first response signal,said second storage device includes a second responder which generates a second response signal, andsaid detector detects whether said first storage device is attached to said first slot and whether said second storage device is attached to said second slot, based on said first response signal from said first responder and said second response signal from said second responder;and further wherein said first response signal includes a first priority information indicating that the first response signal has relatively high priority,said second response signal includes a second priority information indicating that the second response signal has relatively low priority, andsaid detector detects that said first responder has higher priority over said second responder, based on said first and second priority information to activate said first storage device prior to said second storage device.
