# project. The module is, however, dual licensed under OpenSSL and
# CRYPTOGAMS licenses depending on where you obtain it. For further
# details see http://www.openssl.org/~appro/cryptogams/.

# This is RC4+MD5 "stitch" implementation. The idea, as spelled in
# http://download.intel.com/design/intarch/papers/323686.pdf, is that
# since both algorithms exhibit instruction-level parallelism, ILP,
# below theoretical maximum, interleaving them would allow to utilize
# processor resources better and achieve better performance. RC4
# instruction sequence is virtually identical to rc4-x86_64.pl, which
# is heavily based on submission by Maxim Perminov, Maxim Locktyukhin
# and Jim Guilford of Intel. MD5 is fresh implementation aiming to
# minimize register usage, which was used as "main thread" with RC4
# weaved into it, one RC4 round per one MD5 round. In addition to the
# stiched subroutine the script can generate standalone replacement
# md5_block_asm_data_order and RC4. Below are performance numbers in
# cycles per processed byte, less is better, for these the standalone
# subroutines, sum of them, and stitched one:
#
# RC4 MD5 RC4+MD5 stitch gain
# Opteron 6.5(*) 5.4 11.9 7.0 +70%(*)
# Core2 6.5 5.8 12.3 7.7 +60%
# Westmere 4.3 5.2 9.5 7.0 +36%
# Sandy Bridge 4.2 5.5 9.7 6.8 +43%
# Atom 9.3 6.5 15.8 11.1 +42%
#
# (*) rc4-x86_64.pl delivers 5.3 on Opteron, so real improvement
# is +53%...
