Last change on this file since 1253 was 1209, checked in by hhi, 9 years ago

Alignment and reactivation of DMM and depth encoder optimizations:

  • new macro NH_3D_DMM for DMM functionality, including several clean-ups.
  • new macro NH_3D_SDC for SDC functionality, currently only used for covering common SDC and DMM parts.
  • new macro NH_3D_ENC_DEPTH for encoder optimizations related to depth.
  • temporary macro TEMP_SDC_CLEANUP for covering several proposed cleanups related to SDC and DMM.
  • Property svn:eol-style set to native
