| # This is AESNI-CBC+SHA256 stitch implementation. The idea, as spelled |
| # in http://download.intel.com/design/intarch/papers/323686.pdf, is |
| # that since AESNI-CBC encrypt exhibit *very* low instruction-level |
| # parallelism, interleaving it with another algorithm would allow to |
| # utilize processor resources better and achieve better performance. |
| # SHA256 instruction sequences(*) are taken from sha512-x86_64.pl and |
| # AESNI code is weaved into it. As SHA256 dominates execution time, |
| # stitch performance does not depend on AES key length. Below are |
| # performance numbers in cycles per processed byte, less is better, |
| # for standalone AESNI-CBC encrypt, standalone SHA256, and stitched |
| # subroutine: |
| # |
| # AES-128/-192/-256+SHA256 this(**) gain |
| # Sandy Bridge 5.05/6.05/7.05+11.6 13.0 +28%/36%/43% |
| # Ivy Bridge 5.05/6.05/7.05+10.3 11.6 +32%/41%/50% |
| # Haswell 4.43/5.29/6.19+7.80 8.79 +39%/49%/59% |
| # Skylake 2.62/3.14/3.62+7.70 8.10 +27%/34%/40% |
| # Bulldozer 5.77/6.89/8.00+13.7 13.7 +42%/50%/58% |
| # Ryzen(***) 2.71/-/3.71+2.05 2.74/-/3.73 +74%/-/54% |
| # Goldmont(***) 3.82/-/5.35+4.16 4.73/-/5.94 +69%/-/60% |
| # |
| # (*) there are XOP, AVX1 and AVX2 code paths, meaning that |
| # Westmere is omitted from loop, this is because gain was not |
| # estimated high enough to justify the effort; |
| # (**) these are EVP-free results, results obtained with 'speed |
