/* file: 3gpplte_turbo_decoder_sse_16bit.c
   purpose: Routines for implementing max-logmap decoding of Turbo-coded (DLSCH) transport channels from 36-212, V8.6 2009-03
   authors: raymond.knopp@eurecom.fr, Laurent Thomas (Alcatel-Lucent)
25
   date: 21.10.2009
26 27 28

   Note: This version of the routine currently requires SSE2,SSSE3 and SSE4.1 equipped computers.  It uses 16-bit inputs for
         LLRS and uses 16-bit arithmetic for the internal computations!

   Changelog: 17.11.2009 FK SSE4.1 not required anymore
   Aug. 2012 new parallelization options for higher speed (8-way parallelization)
   Jan. 2013 8-bit LLR support with 16-way parallelization
   Feb. 2013 New interleaving and hard-decision optimizations (L. Thomas)
   May 2013 Extracted 16bit code
