19 # This is AESNI-CBC+SHA1 "stitch" implementation. The idea, as spelled
20 # in http://download.intel.com/design/intarch/papers/323686.pdf, is
21 # that since AESNI-CBC encrypt exhibit *very* low instruction-level
22 # parallelism, interleaving it with another algorithm would allow to
23 # utilize processor resources better and achieve better performance.
24 # SHA1 instruction sequences(*) are taken from sha1-x86_64.pl and
25 # AESNI code is weaved into it. Below are performance numbers in
26 # cycles per processed byte, less is better, for standalone AESNI-CBC
27 # encrypt, sum of the latter and standalone SHA1, and "stitched"
28 # subroutine:
29 #
30 # AES-128-CBC +SHA1 stitch gain
31 # Westmere 3.77[+5.3] 9.07 6.55 +38%
32 # Sandy Bridge 5.05[+5.0(6.1)] 10.06(11.15) 5.98(7.05) +68%(+58%)
33 # Ivy Bridge 5.05[+4.6] 9.65 5.54 +74%
34 # Haswell 4.43[+3.6(4.2)] 8.00(8.58) 4.55(5.21) +75%(+65%)
35 # Skylake 2.63[+3.5(4.1)] 6.17(6.69) 4.23(4.44) +46%(+51%)
36 # Bulldozer 5.77[+6.0] 11.72 6.37 +84%
37 #
38 # AES-192-CBC
39 # Westmere 4.51 9.81 6.80 +44%
40 # Sandy Bridge 6.05 11.06(12.15) 6.11(7.19) +81%(+69%)
41 # Ivy Bridge 6.05 10.65 6.07 +75%
42 # Haswell 5.29 8.86(9.44) 5.32(5.32) +67%(+77%)
43 # Bulldozer 6.89 12.84 6.96 +84%
44 #
45 # AES-256-CBC
46 # Westmere 5.25 10.55 7.21 +46%
47 # Sandy Bridge 7.05 12.06(13.15) 7.12(7.72) +69%(+70%)
48 # Ivy Bridge 7.05 11.65 7.12 +64%
49 # Haswell 6.19 9.76(10.34) 6.21(6.25) +57%(+65%)
50 # Skylake 3.62 7.16(7.68) 4.56(4.76) +57%(+61$)
51 # Bulldozer 8.00 13.95 8.25 +69%

53 # (*) There are two code paths: SSSE3 and AVX. See sha1-568.pl for
54 # background information. Above numbers in parentheses are SSSE3
55 # results collected on AVX-capable CPU, i.e. apply on OSes that
56 # don't support AVX.
57 #
58 # Needless to mention that it makes no sense to implement "stitched"
59 # *decrypt* subroutine. Because *both* AESNI-CBC decrypt and SHA1
60 # fully utilize parallelism, so stitching would not give any gain
61 # anyway. Well, there might be some, e.g. because of better cache
62 # locality... For reference, here are performance results for
63 # standalone AESNI-CBC decrypt:
64 #
65 # AES-128-CBC AES-192-CBC AES-256-CBC
66 # Westmere 1.25 1.50 1.75
67 # Sandy Bridge 0.74 0.91 1.09
68 # Ivy Bridge 0.74 0.90 1.11
69 # Haswell 0.63 0.76 0.88
70 # Bulldozer 0.70 0.85 0.99
71
72 # And indeed:
73 #
74 # AES-256-CBC +SHA1 stitch gain
75 # Westmere 1.75 7.20 6.68 +7.8%
76 # Sandy Bridge 1.09 6.09(7.22) 5.82(6.95) +4.6%(+3.9%)
77 # Ivy Bridge 1.11 5.70 5.45 +4.6%
78 # Haswell 0.88 4.45(5.00) 4.39(4.69) +1.4%(*)(+6.6%)
79 # Bulldozer 0.99 6.95 5.95 +17%(**)
80 #
81 # (*) Tiny improvement coefficient on Haswell is because we compare
82 # AVX1 stitch to sum with AVX2 SHA1.
83 # (**) Execution is fully dominated by integer code sequence and
84 # SIMD still hardly shows [in single-process benchmark;-]
