A method for managing execution by a processor of a software architecture included in a radiocommunication circuit is provided. The software architecture includes a radiocommunication software stack and at least one client application. The has the following steps, for a given frequency of the processor: a) obtaining a first computing power associated with the stack; b) obtaining a second computing power associated with the at least one client application; c) computing the sum of the first and second computing powers; d) comparing the sum with a predetermined threshold; e) detecting, based on the result of the comparison step, that the second computing power is insufficient for the processor to execute the at least one client application; and f) in the case of positive detection, restraining at least one functionality of the stack.
