12# This is AESNI-CBC+SHA1 "stitch" implementation. The idea, as spelled
13# in http://download.intel.com/design/intarch/papers/323686.pdf, is
14# that since AESNI-CBC encrypt exhibit *very* low instruction-level
15# parallelism, interleaving it with another algorithm would allow to
16# utilize processor resources better and achieve better performance.
17# SHA1 instruction sequences(*) are taken from sha1-x86_64.pl and
18# AESNI code is weaved into it. Below are performance numbers in
19# cycles per processed byte, less is better, for standalone AESNI-CBC
20# encrypt, sum of the latter and standalone SHA1, and "stitched"
21# subroutine:
22#
23# AES-128-CBC +SHA1 stitch gain
24# Westmere 3.77[+5.6] 9.37 6.65 +41%
25# Sandy Bridge 5.05[+5.2(6.3)] 10.25(11.35) 6.16(7.08) +67%(+60%)
26#
27# AES-192-CBC
28# Westmere 4.51 10.11 6.97 +45%
29# Sandy Bridge 6.05 11.25(12.35) 6.34(7.27) +77%(+70%)
30#
31# AES-256-CBC
32# Westmere 5.25 10.85 7.25 +50%
33# Sandy Bridge 7.05 12.25(13.35) 7.06(7.70) +74%(+73%)
34#
35# (*) There are two code paths: SSSE3 and AVX. See sha1-568.pl for
36# background information. Above numbers in parentheses are SSSE3
37# results collected on AVX-capable CPU, i.e. apply on OSes that
38# don't support AVX.
39#
40# Needless to mention that it makes no sense to implement "stitched"
41# *decrypt* subroutine. Because *both* AESNI-CBC decrypt and SHA1
42# fully utilize parallelism, so stitching would not give any gain
43# anyway. Well, there might be some, e.g. because of better cache
44# locality... For reference, here are performance results for
45# standalone AESNI-CBC decrypt:
46#
47# AES-128-CBC AES-192-CBC AES-256-CBC
48# Westmere 1.31 1.55 1.80
49# Sandy Bridge 0.93 1.06 1.22
