Abstract

A data processing system comprising a memory adapted to store a plurality of data words and a plurality of instruction words of which at least one contains an address used to find said data word and the first information that allows finding in the data word found and in combination with the second information a word part defined by said first and second information, characterized in that said second information (X12-X15) is contained in a second data word (X00-X15), having provided means for extracting said portion of said first data word (SLO-SL3) with the help of said first and second information.
