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/. -# ==================================================================== - -# "[Re]written" was achieved in two major overhauls. In 2004 BODY_* -# functions were re-implemented to address P4 performance issue [see -# commentary below], and in 2006 the rest was rewritten in order to -# gain freedom to liberate licensing terms. - -# January, September 2004. -# -# It was noted that Intel IA-32 C compiler generates code which -# performs ~30% *faster* on P4 CPU than original *hand-coded* -# SHA1 assembler implementation. To address this problem (and -# prove that humans are still better than machines:-), the -# original code was overhauled, which resulted in following -# performance changes: -# -# compared with original compared with Intel cc -# assembler impl. generated code -# Pentium -16% +48% -# PIII/AMD +8% +16% -# P4 +85%(!) +45% -# -# As you can see Pentium came out as looser:-( Yet I reckoned that -# improvement on P4 outweights the loss and incorporate this -# re-tuned code to 0.9.7 and later. -# ---------------------------------------------------------------- -# <appro@fy.chalmers.se> - -# August 2009. -# -# George Spelvin has tipped that F_40_59(b,c,d) can be rewritten as -# '(c&d) + (b&(c^d))', which allows to accumulate partial results -# and lighten "pressure" on scratch registers. This resulted in -# >12% performance improvement on contemporary AMD cores (with no -# degradation on other CPUs:-). Also, the code was revised to maximize -# "distance" between instructions producing input to 'lea' instruction -# and the 'lea' instruction itself, which is essential for Intel Atom -# core and resulted in ~15% improvement. - -# October 2010. -# -# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it -# is to offload message schedule denoted by Wt in NIST specification, -# or Xupdate in OpenSSL source, to SIMD unit. The idea is not novel, -# and in SSE2 context was first explored by Dean Gaudet in 2004, see -# http://arctic.org/~dean/crypto/sha1.html. Since then several things -# have changed that made it interesting again: -# -# a) XMM units became faster and wider; -# b) instruction set became more versatile; -# c) an important observation was made by Max Locktykhin, which made -# it possible to reduce amount of instructions required to perform -# the operation in question, for further details see -# http://software.intel.com/en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1/. - -# April 2011. -# -# Add AVX code path, probably most controversial... The thing is that -# switch to AVX alone improves performance by as little as 4% in -# comparison to SSSE3 code path. But below result doesn't look like -# 4% improvement... Trouble is that Sandy Bridge decodes 'ro[rl]' as -# pair of µ-ops, and it's the additional µ-ops, two per round, that -# make it run slower than Core2 and Westmere. But 'sh[rl]d' is decoded -# as single µ-op by Sandy Bridge and it's replacing 'ro[rl]' with -# equivalent 'sh[rl]d' that is responsible for the impressive 5.1 -# cycles per processed byte. But 'sh[rl]d' is not something that used -# to be fast, nor does it appear to be fast in upcoming Bulldozer -# [according to its optimization manual]. Which is why AVX code path -# is guarded by *both* AVX and synthetic bit denoting Intel CPUs. -# One can argue that it's unfair to AMD, but without 'sh[rl]d' it -# makes no sense to keep the AVX code path. If somebody feels that -# strongly, it's probably more appropriate to discuss possibility of -# using vector rotate XOP on AMD... - -###################################################################### -# Current performance is summarized in following table.
