1. An integrated circuit device for multiplexing parallel data of a plurality of parallel interfaces into serial data, said integrated circuit device, comprising:

  • a storage device,a signal send-out circuit which outputs data on a one-bit basis to a transmission path connected to said integrated circuit device, said data being stored in said storage device,an interface-signal selector which outputs parallel data of selected parallel interfaces to said storage device, said interface-signal selector being so configured as to be able to input said parallel data of said plurality of parallel interfaces, anda transfer programmer which issues a control signal to said interface-signal selector, said control signal notifying said interface-signal selector of said parallel interfaces which are to be selected thereby,wherein said storage device has a plurality of slots each storing the data output from the interface-signal selector for a respective parallel interface of the plurality of parallel interfaces as serial data,wherein said storage device has a header information part which stores header information indicating which one of said plurality of parallel interfaces uses which one of the plurality of slots and in order in which the interface-signal selector selects the parallel interfaces, andwherein said signal send-out circuit outputs said header information in addition to said serial data stored in said plurality of slots on a one bit basis to said transmission path.
