Abstract
A split data word including a portion of each of two word-aligned data words stored at two word-aligned address boundaries within a memory is read from a displaced-read memory address relative to the word-aligned address boundaries within the memory. The portions of each of the two word-aligned data words within the split data word are compared with corresponding portions of a word-aligned search pattern. A determination is made that a potential complete match for the word-aligned search pattern exists within at least one of the two word-aligned data words based upon an identified match of at least one of the portions of the two word-aligned data words within the split data word with a corresponding at least one portion of the word-aligned search pattern.
