   9 # Version 1.0.
  10 #
  11 # aes-*-cbc benchmarks are improved by 50% [compared to gcc 3.3.2 on
  12 # Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
  13 # [you'll notice a lot of resemblance], such as compressed S-boxes
  14 # in little-endian byte order, prefetch of these tables in CBC mode,
  15 # as well as avoiding L1 cache aliasing between stack frame and key
  16 # schedule and already mentioned tables.
  17 #
  18 # Performance in number of cycles per processed byte for 128-bit key:
  19 #
  20 #               ECB             CBC encrypt
  21 # AMD64         15.6            14.6(*)
  22 # EM64T         23.3(**)        21.4(*)
  23 #
  24 # (*)   CBC benchmarks are better than ECB thanks to custom ABI used
  25 #       by the private block encryption function.
  26 # (**)  This module exhibits virtually same ECB performance as 32-bit
  27 #       counterpart on [current] Intel CPU.
