Abstract: A method for synchronizing a content stream (10) and a script (70) comprises the acts of calculating (80) a fingerprint (30) comprising a number of bits, from a portion (20) of the content stream; determining (50) a time value (40) corresponding to the calculated fingerprint (30); synchronizing a portion of the script (90) that corresponds to the time value (40) and the portion (20) of the content stream (10). The method is characterized in comprising a step in which the number of bits is determined in dependence of at least one of the fingerprints chosen from a group comprising the calculated fingerprint (30), an expected fingerprint (130) corresponding to said calculated fingerprint, another calculated fingerprint (110) calculated from another portion (100) of said content stream, and another expected fingerprint (120) corresponding to said another calculated fingerprint (110). The script (70) represents one or more sensory effects to be output in an effects signal to an effects controller.

Abstract: A score is computed of how many cache misses occur for the execution of each of a number of blocks. The score is used as a heuristic in a local search in which an original selection is iteratively replaced each time by a selection that differs from the original selection only by the movement of a single block and that has a lower number of cache misses for the sample of execution than the original selection. Thus a selection of locations for placing instructions of a program in main memory is found that minimizes the number of cache misses that occur for a sample of a typical execution of the program.
