Abstract: A computing device divides an area of a main memory wherein a data structure is saved into NbS1 subdivisions, and then the computing device computes a weight wS,NbS1(k) for each of the NbS1 subdivisions using the following relationship: wS,NbS1(k)=PS(1+(k?1)×(NbS0?1)/(NbS1?1)), where: k is the order number k of one of the NbS1 subdivisions, and PS( ) is a predetermined function that is continuous over an interval [1; NbS0] and defined over each interval [k0, k0+1] by a polynomial of order less than four, where k0 is an integer order number contained in the interval [1; NbS0], and then when a datum Dk,n contained in a subdivision k of the main memory has to be transferred to a secondary memory, the computing device transfers a block of wS,NbS1(k) data containing the datum Dk,n where wS,NbS1(k) is the weight computed for this subdivision k.

Abstract: Method for constructing a signature characteristic of the accesses, by a microprocessor, to a memory wherein: each time the microprocessor executes an access instruction for accessing a datum of a data structure, the microprocessor retrieves the identifier of the data structure and a position identifier that identifies the position of the datum accessed inside this data structure, the temporally ordered series of the position identifiers thus retrieved forming a retrieved access pattern, then for each retrieved access pattern associated with one and the same data structure identifier, the microprocessor constructs a statistical distribution on the basis of just the position identifiers of this retrieved access pattern, the set of the statistical distributions thus constructed and associated with the identifier of this data structure forming the signature characteristic of the accesses to the memory.
