The invention concerns a controlled frequency core processor. It comprise s at least one processor, a non-volatile memory comprising a start-up progra m, a bridge interconnecting the busses which link the different components o f said core processor, an interface component. The non-volatile memory compr ises at least two corresponding configurations with respect to the frequency , each of which has a mode of operation of the busses and/ or of the compone nts of said core processor. The non-volatile memory comprises an information which allows for determining which mode of operation has to be used, wherei n said information is read by the interface component in order to determine the selected mode. The interface component generates one or several clock si gnals. The frequency of said clock signals generated substantially correspon ds to the one described by the configuration of the selected mode. The clock signals control the busses and/ or the components of said core processor. T he invention also concerns a method for starting-up said core processor in a programmed manner. In particular, the invention is applied to core processo rs installed in an aircraft.
