Реферат: Control device (3) for the operation of a load, in particular at least one gas discharge lamp (10, 15). The control device (3) is divided into a first purely software controlled control unit (3a) a second control unit (3b) realized purely in hardware. The two control units (3a, 3b) are connected with one another via a bidirectional connection line, the second control unit receiving exclusively internal operating state information (Iintern) and the first control unit (3a) receiving external control information (Iextern) By means of the division of the control device into a purely software controlled control unit (3a) and a control unit constructed purely of hardware (3b) the control device (3) in accordance with the invention has both a speed sufficient for rapid control procedures and also a sufficient flexibility with regard to alterations. Advantageously, the control device (3) in accordance with the invention is employed in an electronic ballast for the operation of gas discharge lamps (10, 15).
