And given their throughput asymptotic 20# performance for parallelizable modes is 1.25 cycles per byte. Being 21# asymptotic limit it's not something you commonly achieve in reality, 22# but how close does one get? Below are results collected for 23# different modes and block sized. Pairs of numbers are for en-/ 24# decryption. 25# 26# 16-byte 64-byte 256-byte 1-KB 8-KB 27# ECB 4.25/4.25 1.38/1.38 1.28/1.28 1.26/1.26 1.26/1.26 28# CTR 5.42/5.42 1.92/1.92 1.44/1.44 1.28/1.28 1.26/1.26 29# CBC 4.38/4.43 4.15/1.43 4.07/1.32 4.07/1.29 4.06/1.28 30# CCM 5.66/9.42 4.42/5.41 4.16/4.40 4.09/4.15 4.06/4.07 31# OFB 5.42/5.42 4.64/4.64 4.44/4.44 4.39/4.39 4.38/4.38 32# CFB 5.73/5.85 5.56/5.62 5.48/5.56 5.47/5.55 5.47/5.55 33# 34# ECB, CTR, CBC and CCM results are free from EVP overhead.

All above results are consistently better. This 41# module also provides better performance for block sizes smaller than 42# 128 bytes in points *not* represented in the above table. 43# 44# Looking at the results for 8-KB buffer. 45# 46# CFB and OFB results are far from the limit, because implementation 47# uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on 48# single-block aesni_encrypt, which is not the most optimal way to go. 49# CBC encrypt result is unexpectedly high and there is no documented 50# explanation for it. Seemingly there is a small penalty for feeding 51# the result back to AES unit the way it's done in CBC mode. There is 52# nothing one can do and the result appears optimal. CCM result is 53# identical to CBC, because CBC-MAC is essentially CBC encrypt without 54# saving output. CCM CTR "stays invisible," because it's neatly 55# interleaved with CBC-MAC. This provides ~30% improvement over 56# "straghtforward" CCM implementation with CTR and CBC-MAC performed 57# disjointly. Parallelizable modes practically achieve the theoretical 58# limit. 59# 60# Looking at how results vary with buffer size. 61# 62# Curves are practically saturated at 1-KB buffer size. In most cases 63# "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one. 64# CTR curve doesn't follow this pattern and is "slowest" changing one 65# with "256-byte" result being 87% of "8-KB." This is because overhead 66# in CTR mode is most computationally intensive. Small-block CCM 67# decrypt is slower than encrypt, because first CTR and last CBC-MAC 68# iterations can't be interleaved. 69# 70# Results for 192- and 256-bit keys. 71# 72# EVP-free results were observed to scale perfectly with number of 73# rounds for larger block sizes, i.e. 192-bit result being 10/12 times 74# lower and 256-bit one - 10/14. Well, in CBC encrypt case differences 75# are a tad smaller, because the above mentioned penalty biases all 76# results by same constant value. In similar way function call 77# overhead affects small-block performance, as well as OFB and CFB 78# results. Differences are not large, most common coefficients are 79# 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one 80# observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)... 81 82# January 2011 83# 84# While Westmere processor features 6 cycles latency for aes[enc|dec] 85# instructions, which can be scheduled every second cycle, Sandy 86# Bridge spends 8 cycles per instruction, but it can schedule them 87# every cycle. This means that code targeting Westmere would perform 88# suboptimally on Sandy Bridge. Therefore this update. 89# 90# In addition, non-parallelizable CBC encrypt (as well as CCM) is 91# optimized. Relative improvement might appear modest, 8% on Westmere, 92# but in absolute terms it's 3.77 cycles per byte encrypted with 93# 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers 94# should be compared to asymptotic limits of 3.75 for Westmere and 95# 5.00 for Sandy Bridge. Actually, the fact that they get this close 96# to asymptotic limits is quite amazing. Indeed, the limit is 97# calculated as latency times number of rounds, 10 for 128-bit key, 98# and divided by 16, the number of bytes in block, or in other words 99# it accounts *solely* for aesenc instructions. But there are extra 100# instructions, and numbers so close to the asymptotic limits mean 101# that it's as if it takes as little as *one* additional cycle to 102# execute all of them. How is it possible? It is possible thanks to 103# out-of-order execution logic, which manages to overlap post- 104# processing of previous block, things like saving the output, with 105# actual encryption of current block, as well as pre-processing of 106# current block, things like fetching input and xor-ing it with 107# 0-round element of the key schedule, with actual encryption of 108# previous block. Keep this in mind... 109# 110# For parallelizable modes, such as ECB, CBC decrypt, CTR, higher 111# performance is achieved by interleaving instructions working on 112# independent blocks. In which case asymptotic limit for such modes 113# can be obtained by dividing above mentioned numbers by AES 114# instructions' interleave factor. Westmere can execute at most 3 115# instructions at a time, meaning that optimal interleave factor is 3, 116# and that's where the "magic" number of 1.25 come from. "Optimal 117# interleave factor" means that increase of interleave factor does 118# not improve performance. The formula has proven to reflect reality 119# pretty well on Westmere... Sandy Bridge on the other hand can 120# execute up to 8 AES instructions at a time, so how does varying 121# interleave factor affect the performance? Here is table for ECB 122# (numbers are cycles per byte processed with 128-bit key): 123# 124# instruction interleave factor 3x 6x 8x 125# theoretical asymptotic limit 1.67 0.83 0.625 126# measured performance for 8KB block 1.05 0.86 0.84 127# 128# "as if" interleave factor 4.7x 5.8x 6.0x 129# 130# Further data for other parallelizable modes: 131# 132# CBC decrypt 1.16 0.93 0.93 133# CTR 1.14 0.91 n/a 134# 135# Well, given 3x column it's probably inappropriate to call the limit 136# asymptotic, if it can be surpassed, isn't it? What happens there? 137# Rewind to CBC paragraph for the answer. Yes, out-of-order execution 138# magic is responsible for this. Processor overlaps not only the 139# additional instructions with AES ones, but even AES instructions 140# processing adjacent triplets of independent blocks. In the 6x case 141# additional instructions still claim disproportionally small amount 142# of additional cycles, but in 8x case number of instructions must be 143# a tad too high for out-of-order logic to cope with, and AES unit 144# remains underutilized... As you can see 8x interleave is hardly 145# justifiable, so there no need to feel bad that 32-bit aesni-x86.pl 146# utilizies 6x interleave because of limited register bank capacity. 147# 148# Higher interleave factors do have negative impact on Westmere 149# performance. While for ECB mode it's negligible ~1.5%, other 150# parallelizables perform ~5% worse, which is outweighed by ~25% 151# improvement on Sandy Bridge. To balance regression on Westmere 152# CTR mode was implemented with 6x aesenc interleave factor. 153 154# April 2011 155# 156# Add aesni_xts_[en|de]crypt. Westmere spends 1.33 cycles processing 157# one byte out of 8KB with 128-bit key, Sandy Bridge - 0.97. Just like 158# in CTR mode AES instruction interleave factor was chosen to be 6x. 159 160$PREFIX="aesni"; # if $PREFIX is set to "AES", the script 161 # generates drop-in replacement for 162 # crypto/aes/asm/aes-x86_64.pl:-) 163 164$flavour = shift; 165$output = shift; 166if ($flavour =~ /\./) { $output = $flavour; undef $flavour; } 167 168$win64=0; $win64=1 if ($flavour =~ /[nm]asm|mingw64/ || $output =~ /\.asm$/); 169 170$0 =~ m/(.*[\/\\])[^\/\\]+$/; $dir=$1; 171( $xlate="${dir}x86_64-xlate.pl" and -f $xlate ) or 172( $xlate="${dir}../../perlasm/x86_64-xlate.pl" and -f $xlate) or 173die "can't locate x86_64-xlate.pl"; 174 175open OUT,"| \"$^X\" $xlate $flavour $output"; 176*STDOUT=*OUT; 177 178$movkey = $PREFIX eq "aesni" ?
