PROBLEM TO BE SOLVED: To provide a small-scale circuit for inspecting that only one signal line among N signal lines is in a drive state. SOLUTION: An inspection unit 10, which comprises a 1st inspection part 11 which inspects that at least one signal line among N signal lines, is in a drive state, and a 2nd inspection part 12 which inspects that two or more signal lines among N signal lines are not in drive states outputs the results of previous inspections which are inputted from CHECK-1-IN' and CHECK-2-IN' and the results of inspections, to which new signal line information data inputted by DATAi are added. N such inspection units 10 are connected to each other to form a chain. Furthermore, in a reconfigurable processor, floating and conflict of buses are tested by the inspection circuit to generate exceptions, when errors are detected.
