+
+   This implementation assumes little endian mode.  For big endian mode,

+   The algorithm is fairly straightforward: search byte by byte until we

+
+   The word by word search is performed by xor-ing the word with a word

+   contain a zero byte in the corresponding position.  The presence and 
+   position of that zero byte is detected with a czx instruction.
