<p>A device (11) capable of externally setting and modifying internal functions and a data processing apparatus using such a device are provided, outside the data processing apparatus, with a function data setting unit (12) for reading and writing data for use in setting, modifying, and storing the internal functions; and an execution state stack unit (13) for storing data indicating the state of the internal functions being executed. The data processing apparatus includes an internal resource management unit (14) for setting and modifying the internal functions, and saving and restoring, through the execution state stack unit, the data indicating the state of the functions being executed. This system allows the processes to be freely performed by the device and the data processing apparatus at a high speed. <IMAGE></p> |
