| 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" |
| 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. |

| 21 # Rescheduling instructions to favour Power6 pipeline gives 10% |
| 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). |
