| 22 | # September 2011. | |
| 23 | # | |
| 24 | # Started as transliteration to "perlasm" the original code has | |
| 25 | # undergone following changes: | |
| 26 | # | |
| 27 | # - code was made position-independent; | |
| 28 | # - rounds were folded into a loop resulting in >5x size reduction | |
| 29 | # from 12.5KB to 2.2KB; | |
| 79c44b4e | 30 | # - above was possible thanks to mixcolumns() modification that |
| 4ec93a10 AP |
31 | # allowed to feed its output back to aesenc[last], this was |
| 32 | # achieved at cost of two additional inter-registers moves; | |
| 33 | # - some instruction reordering and interleaving; | |
| 34 | # - this module doesn't implement key setup subroutine, instead it | |
| 35 | # relies on conversion of "conventional" key schedule as returned | |
| 36 | # by AES_set_encrypt_key (see discussion below); | |
| 37 | # - first and last round keys are treated differently, which allowed | |
| 38 | # to skip one shiftrows(), reduce bit-sliced key schedule and | |
| 39 | # speed-up conversion by 22%; | |
| 40 | # - support for 192- and 256-bit keys was added; | |
| 41 | # | |
| 42 | # Resulting performance in CPU cycles spent to encrypt one byte out | |
| 43 | # of 4096-byte buffer with 128-bit key is: | |
| 44 | # | |
| 45 | # Emilia's this(*) difference | |
| 46 | # | |
| 47 | # Core 2 9.30 8.69 +7% | |

| b59f92e7 | 50 | # Silvermont - 12.9 |
| ace05265 | 51 | # Goldmont - 8.85 |
| 4ec93a10 AP |
52 | # |
| 53 | # (*) Comparison is not completely fair, because "this" is ECB, | |
| 54 | # i.e. no extra processing such as counter values calculation | |
| 55 | # and xor-ing input as in Emilia's CTR implementation is | |
| 56 | # performed. However, the CTR calculations stand for not more | |
| 57 | # than 1% of total time, so comparison is *rather* fair. | |
| 58 | # | |
| 59 | # (**) Results were collected on Westmere, which is considered to | |
| 60 | # be equivalent to Nehalem for this code. | |
| 61 | # | |
| 4ec93a10 AP |
62 | # As for key schedule conversion subroutine. Interface to OpenSSL |
| 63 | # relies on per-invocation on-the-fly conversion. This naturally | |
| 64 | # has impact on performance, especially for short inputs. Conversion | |
| 65 | # time in CPU cycles and its ratio to CPU cycles spent in 8x block | |
| 66 | # function is: | |
| 67 | # | |
| 68 | # conversion conversion/8x block | |

69 | # Core 2 240 0.22 |
| 70 | # Nehalem 180 0.20 | |
| 558ff0f0 | 71 | # Atom 430 0.20 |
| 4ec93a10 AP |
72 | # |
| 73 | # The ratio values mean that 128-byte blocks will be processed | |
| f9ef874a | 74 | # 16-18% slower, 256-byte blocks - 9-10%, 384-byte blocks - 6-7%, |
| 4ec93a10 AP |
75 | # etc. Then keep in mind that input sizes not divisible by 128 are |
| 76 | # *effectively* slower, especially shortest ones, e.g. consecutive | |
| 77 | # 144-byte blocks are processed 44% slower than one would expect, | |
| 78 | # 272 - 29%, 400 - 22%, etc. Yet, despite all these "shortcomings" | |
| 79 | # it's still faster than ["hyper-threading-safe" code path in] | |
