Abstract
The data processing device comprising at least two processing units, each processing unit (CR1, CR2) being alternately in a first operating mode and in a second operating mode, each processing unit switching to its second operating mode at the end of a transient phase (PHT1, PHT2) comprising at least one activation of resources common to these two processing units; at least one of the two units is configured to switch at least once to its second operating mode with a temporal flexibility, and the instant of switching to its second operating mode, of the processing unit or units exhibiting the said flexibility, is adjusted in such a way that the two units are in their second operating mode after the said common resources have been activated once (26) in the course of the two respective transient phases, if this temporal adjustment is compatible with the said temporal flexibility.
