1. A method for operating a multiprocessor system comprising a plurality of data processing cells, each of the plurality of data processing units (a) including at least one Arithmetic Logic Unit (ALU) and a register unit and (b) being adapted for sequentially processing data, the method comprising: the multiprocessor system setting a clock frequency, of at least a part of the multiprocessor system to a minimum in accordance with a number of pending operations of a first processor; the multiprocessor system subsequently increasing the clock frequency of the at least the part of the multiprocessor system to a maximum in accordance with a number of pending operations of a second processor; and the multiprocessor system subsequently reducing the clock frequency of the at least the part of the multiprocessor system in accordance with (a) an operating temperature threshold preventing over-temperature and (b) a hysteresis characteristic.
