# ====================================================================
|

# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
|
||||
# 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/.
|
||||
# ====================================================================
|
||||
#
|
||||
# May 2011
|
||||
#
|
||||
# The module implements bn_GF2m_mul_2x2 polynomial multiplication used
|
||||
# in bn_gf2m.c. It's kind of low-hanging mechanical port from C for
|
||||
# the time being... Except that it has three code paths: pure integer
|
||||
# code suitable for any x86 CPU, MMX code suitable for PIII and later
|
||||
# and PCLMULQDQ suitable for Westmere and later. Improvement varies
|
||||
# from one benchmark and µ-arch to another. Below are interval values
|
||||
# for 163- and 571-bit ECDH benchmarks relative to compiler-generated
|
||||
# code:
|
||||
#
|
||||
# PIII 16%-30%
|
||||
# P4 12%-12%
|
||||
# Opteron 18%-40%
|
||||
# Core2 19%-44%
|
||||
# Atom 38%-64%
|
||||
# Westmere 53%-121%(PCLMULQDQ)/20%-32%(MMX)
|
||||
# Sandy Bridge 72%-127%(PCLMULQDQ)/27%-23%(MMX)
|
||||
#
|
||||
# Note that above improvement coefficients are not coefficients for
|
||||
# bn_GF2m_mul_2x2 itself. For example 120% ECDH improvement is result
|
||||
# of bn_GF2m_mul_2x2 being >4x faster. As it gets faster, benchmark
|
||||
# is more and more dominated by other subroutines, most notably by
|
||||
# BN_GF2m_mod[_mul]_arr...
