Abstract: A method is provided for calling with a processor an instance of a function present within at least a first software module and required by a second software module, referred to as a calling software module. The method further includes that the calling comprises a step of obtaining a current execution context, where the current execution context depends on at least one execution situation of the calling software module, and the current execution context comprises execution data. The method also includes that the calling step comprises a step of selecting the instance of the function, from at least two available instances, depending on the execution data of the current execution context.

Abstract: The inventive system for automatically generating optimizes codes (19) which are operational on a predefined hardware platform (90) comprises at least one processor which is (91) based on code sources (17) provided by users and comprises means (51, 52) for receiving symbolic code sequences or standard sequences (1) representative for the processor (91) behavior in terms of performance for a predetermined application area, means (53), for receiving static parameters (2), means (55) for receiving dynamic parameters (7), an analysing device (10) for defining optimization rules (9) on the basis of performance tests and measures determined on the basis of the standard sequences (1) and the static (2) and dynamic (7) parameters, a device (80) for optimizing and generating the code receiving the standard sequences (1) and the optimization rules (9) for examining the code sources (17) of the users, detecting optimizable loops, decomposing into cores and for assembling and injecting the codes in such a way that the op
