A mapping-type data signal optimizer performs a code-point sorting function to optimize downloading of programmed symbols. A present-state list of values of programmed symbols already downloaded to a peripheral device is sorted, and a similar intended-state list of programmed symbols intended to be downloaded is likewise sorted. A search is performed to detect any commonalities that might exist between the present-state and intended-state programmed-symbol values, even under differing programmed-symbol designators. When such a commonality is detected, the intended- state designator is altered to be equal to the present-state designator; thus, that particular programmed symbol value need not be redownloaded.
