Abstract
A method of refreshing a dynamic memory intended for storing variables involved in operations performed by a processor, includes a step of planning in the course of which an order and a timing of the operations are established, a step of estimating a retention time specific to each variable, a step of forecasting at least one instant at which each variable must be refreshed, a step of placement in the course of which the variables are placed in the memory, a step of refreshing in the course of which the variables are refreshed at the instants defined during the forecasting step . The method allows a reduction in the latency times and in the consumption of current which are related to the refreshing. It is of particular benefit in systems where the real time constraint is important, for example, video data processing systems.
