# 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 |

# (*) There are two code paths: SSSE3 and AVX. See sha1-568.pl for |
| 45 |
# background information. Above numbers in parentheses are SSSE3 |
| 46 |
# results collected on AVX-capable CPU, i.e. apply on OSes that |
| 47 |
# don't support AVX. |
| 48 |
# |
| 49 |
# Needless to mention that it makes no sense to implement "stitched" |
| 50 |
# *decrypt* subroutine. Because *both* AESNI-CBC decrypt and SHA1 |
| 51 |
# fully utilize parallelism, so stitching would not give any gain |
| 52 |
# anyway. Well, there might be some, e.g. because of better cache |
| 53 |
# locality... For reference, here are performance results for |
| 54 |
# standalone AESNI-CBC decrypt: |

# |

| 61 |
# Bulldozer 0.70 0.85 0.99 |
| 62 |
|

# And indeed: |
| 64 |
# |
| 65 |
# AES-256-CBC +SHA1 stitch gain |
| 66 |
# Westmere 1.75 7.20 6.68 +7.8% |

# Sandy Bridge 1.09 6.09(7.22) 5.82(6.95) +4.6%(+3.9%) |
| 68 |
# Ivy Bridge 1.11 5.70 5.45 +4.6% |
| 69 |
# Haswell 0.88 4.45(5.00) 4.39(4.69) +1.4%(*)(+6.6%) |
| 70 |
# Bulldozer 0.99 6.95 5.95 +17%(**) |
| 71 |
# |
| 72 |
# (*) Tiny improvement coefficient on Haswell is because we compare |
| 73 |
# AVX1 stitch to sum with AVX2 SHA1. |
| 74 |
# (**) Execution is fully dominated by integer code sequence and |
| 75 |
# SIMD still hardly shows [in single-process benchmark;-] |
