  18 @ AES for ARMv4
  19
  20 @ January 2007.
  21 @
  22 @ Code uses single 1K S-box and is >2 times faster than code generated
  23 @ by gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which
  24 @ allows to merge logical or arithmetic operation with shift or rotate
  25 @ in one instruction and emit combined result every cycle. The module
  26 @ is endian-neutral. The performance is ~42 cycles/byte for 128-bit
  27 @ key [on single-issue Xscale PXA250 core].
  28
  29 @ May 2007.
  30 @
  31 @ AES_set_[en|de]crypt_key is added.
  32
  33 @ July 2010.
  34 @
  35 @ Rescheduling for dual-issue pipeline resulted in 12% improvement on
  36 @ Cortex A8 core and ~25 cycles per byte processed with 128-bit key.
  37
  38 @ February 2011.
  39 @
  40 @ Profiler-assisted and platform-specific optimization resulted in 16%
  41 @ improvement on Cortex A8 core and ~21.5 cycles per byte.
