A process for optimizing data and/or program parts for programmed controllers that can be used, e.g., in motor vehicle controllers. In this process, the controller is connected to an external application device via an interface. Changes in the data and/or program parts to be optimized are entered with the help of the application device. This process is characterized in that, at the beginning of the optimizing process, the data and/or program parts are loaded into the data and/or program read-write memory (e.g., RAM) of the controller. In addition, the process is characterized in that specific changes are made in the control program and/or in the memory and/or register locations of the controller to cause the microprocessor of the controller to access the corresponding data and/or program parts in the data and/or program read-write memory (e.g., RAM) instead of accessing the data and/or program parts in the data and/or program read-only memory (e.g., flash EPROM). For a controller to be used in this process, the controller is provided with a decoder circuit that performs a switch when the microprocessor accesses a certain address or a certain address area. As a result of this switch, instead of accessing the data and/or program parts in the data and/or program read-only memory, the microprocessor accesses the corresponding data and/or program parts in the data and/or program read-write memory.

[ What is claimed is:] [3.] A process for optimizing at least one of data and program parts for a programmed controller, comprising the steps of:b. storing a control program in at least one of data and program read-only memory of the programmed controller;b. coupling the programmed controller to an external application device via an interface;c. entering at least one modification in the at least one of data and program parts via the application device;d. loading the at least one of data and program parts to be optimized into at least one of data and program read-write memory of the programmed controller before optimization; ande. modifying at least one of the control program, a read-write memory location and a register location of the programmed controller, wherein the programmed controller, in response thereto, accesses the at least one of data and program parts in the at least one of data and program read-write memory instead of accessing the at least one of data and program parts in the at least one of data and program read-only memory, wherein the step e. includes the steps of:modifying at least one address register of the programmed controller;performing an automatic switch in accordance with entries in the at least one address register; andaccessing the at least one of data and program parts to be optimized in the at least one of data and program read-write memory.
