| 4 | # Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL | |
| 5 | # project. The module is, however, dual licensed under OpenSSL and | |
| 6 | # CRYPTOGAMS licenses depending on where you obtain it. For further | |
| 7 | # details see http://www.openssl.org/~appro/cryptogams/. | |

| 11 | # | |
| 12 | # ppc_AES_[en|de]crypt perform at 18 cycles per byte processed with | |
| 13 | # 128-bit key, which is ~40% better than 64-bit code generated by gcc | |
| 14 | # 4.0. But these are not the ones currently used! Their "compact" | |
| 96b0f6c1 AP |
15 | # counterparts are, for security reason. ppc_AES_encrypt_compact runs |
| 16 | # at 1/2 of ppc_AES_encrypt speed, while ppc_AES_decrypt_compact - | |
| 17 | # at 1/3 of ppc_AES_decrypt. | |

| 67150340 | 21 | # Rescheduling instructions to favour Power6 pipeline gave 10% |
| 109757d2 AP |
22 | # performance improvement on the platfrom in question (and marginal |
| 23 | # improvement even on others). It should be noted that Power6 fails | |
| 24 | # to process byte in 18 cycles, only in 23, because it fails to issue | |
| 25 | # 4 load instructions in two cycles, only in 3. As result non-compact | |
| 26 | # block subroutines are 25% slower than one would expect. Compact | |
| 27 | # functions scale better, because they have pure computational part, | |
| 28 | # which scales perfectly with clock frequency. To be specific | |
| 29 | # ppc_AES_encrypt_compact operates at 42 cycles per byte, while | |
| 30 | # ppc_AES_decrypt_compact - at 55 (in 64-bit build). | |
