The common package includes a programmable device (36), memories (45 to 48) for storing programs to configure the programmable device, a selector (41) for selecting one of the programs from the memory so that the selected program may so configure the programmable device as to make the common package serve as a specific circuit, and an instruction unit (51) for issuing an instruction to specify the program to be selected by the selector.
