ABSTRACT:
In a data processing apparatus, when making an access to a specific object to be accessed, the data processor supplies an access control signal to a plurality of control signal generators. The data processor further supplies accessed object type data to the accessed object type determining circuit. The determining circuit determines the type of the accessed object on the basis of the accessed object type data, and selectively drives the control signal generator corresponding to the accessed object. The control signal generator driven converts the access control signal into a control signal adapted for the accessed object. An address signal and data are transferred between the specific accessed object supplied with this control signal and the data processor via the address bus and data bus.
