Feedback linker for increased delta performance

摘要

A method of generating an updated memory image including updated program code to be loaded into a storage medium that has stored thereon a current memory image including a current program code version. The method comprises receiving an updated input code comprising a number of segments, wherein each segment is relocatable within the updated memory image; arranging the segments within the updated memory image. The arranging further comprises receiving a representation of the current program code version; performing at least one optimisation step adapted to decrease an objective function under at least one predetermined layout constraint, the objective function being indicative of a magnitude of differences between the current program code version and the updated program code version, the layout constraint being indicative of at least one constraint imposed on the arrangement of segments within the memory image.
