In a processing description part 180, macros are used to describe processing in layers L1 and L2 with labels in each layer. A hierarchical configuration description part 191 defines the relation of connection between layers with macros of labels in each layer. An identifier expanding part 192 performs macro expansion. When these parts and a compiler 914 are used, control software that includes only a single expanded layer is obtained. The software obtained is stored in, for example, a ROM 205 or the like in a control unit 200 in an automobile controller. Accordingly, the processing description part 180 can be layered in an easy to understand manner, and thus person-hours for software modification can be localized when hardware or the control method is modified. Furthermore, execution speed of applications can be increased and the necessary capacity of the storage device can be reduced. |
