Abstract
A program-controlled unit includes a core for executing the program to be executed by the program-controlled unit, and debug resources for tracking and influencing the operations proceeding within the core. The program-controlled unit is distinguished by the fact that the debug resources are able also to influence other components of the program-controlled unit and/or the cooperation of these components with one another and/or with the core. Such action makes it possible to avoid to the greatest possible extent, in a simple manner, the situation wherein disturbances or errors that do not occur in normal operation of the program-controlled unit occur during the debugging or emulation of the program-controlled unit, and/or wherein errors that occur in normal operation of the program-controlled unit do not occur during the debugging or emulation of the program-controlled unit.
