The invention relates to a method for effecting the functional control of the program flow and/or data flow in digital signal processors and in processors having closed and separated modules for effecting the program and data flow control, which operate in parallel arithmetic-logic units. The aim of the invention is to enhance the functionality of the processor to such an extent that the units of the processor, without time delays, are adapted, with regard to their energy consumption, to the latest demands of the signal processing and, inside the processor, additional possibilities for saving energy are provided by the algorithm-related shutdown of functional units. To this end, the invention provides that an external hardware-related signal input into the processor or a software-related state output from the program flow of the processor interrupts the clock pulse supply for the respective functional units for the period of time during which these functional units are not used. |
