#!/usr/bin/env perl # ==================================================================== # [Re]written by Andy Polyakov 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/. # ==================================================================== # "[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. # ---------------------------------------------------------------- # # 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... # March 2014. # # Add support for Intel SHA Extensions. ###################################################################### # Current performance is summarized in following table.
