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. # SHA1 instruction sequences(*) are taken from sha1-x86_64.pl and # AESNI code is weaved into it. Below are performance numbers in # cycles per processed byte, less is better, for standalone AESNI-CBC # encrypt, sum of the latter and standalone SHA1, and "stitched" # subroutine: # # AES-128-CBC +SHA1 stitch gain # Westmere 3.77[+5.3] 9.07 6.55 +38% # Sandy Bridge 5.05[+5.0(6.1)] 10.06(11.15) 5.98(7.05) +68%(+58%) # Ivy Bridge 5.05[+4.6] 9.65 5.54 +74% # Haswell 4.43[+3.6(4.2)] 8.00(8.58) 4.55(5.21) +75%(+65%) # Skylake 2.63[+3.5(4.1)] 6.17(6.69) 4.23(4.44) +46%(+51%) # Bulldozer 5.77[+6.0] 11.72 6.37 +84% # Ryzen(**) 2.71[+1.93] 4.64 2.74 +69% # Goldmont(**) 3.82[+1.70] 5.52 4.20 +31% # # AES-192-CBC # Westmere 4.51 9.81 6.80 +44% # Sandy Bridge 6.05 11.06(12.15) 6.11(7.19) +81%(+69%) # Ivy Bridge 6.05 10.65 6.07 +75% # Haswell 5.29 8.86(9.44) 5.32(5.32) +67%(+77%) # Bulldozer 6.89 12.84 6.96 +84% # # AES-256-CBC # Westmere 5.25 10.55 7.21 +46% # Sandy Bridge 7.05 12.06(13.15) 7.12(7.72) +69%(+70%) # Ivy Bridge 7.05 11.65 7.12 +64% # Haswell 6.19 9.76(10.34) 6.21(6.25) +57%(+65%) # Skylake 3.62 7.16(7.68) 4.56(4.76) +57%(+61%) # Bulldozer 8.00 13.95 8.25 +69% # Ryzen(**) 3.71 5.64 3.72 +52% # Goldmont(**) 5.35 7.05 5.76 +22% # # (*) There are two code paths: SSSE3 and AVX.
