| 15 # | |
| 16 # Interface to OpenSSL as "almost" drop-in replacement for | |
| 17 # aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt | |
| 18 # doesn't handle partial vectors (doesn't have to if called from | |
| 19 # EVP only). "Drop-in" implies that this module doesn't share key | |
| 20 # schedule structure with the original nor does it make assumption | |
| 21 # about its alignment... | |
| 22 # | |
| 23 # Performance summary. aes-x86_64.pl column lists large-block CBC | |
| 24 # encrypt/decrypt/with-hyper-threading-off(*) results in cycles per | |
| 25 # byte processed with 128-bit key, and vpaes-x86_64.pl column - | |
| 26 # [also large-block CBC] encrypt/decrypt. | |
| 27 # | |
| 28 # aes-x86_64.pl vpaes-x86_64.pl | |

| 30 # Core 2(**) 30.5/43.7/14.3 21.8/25.7(***) | |
| 31 # Nehalem 30.5/42.2/14.6 9.8/11.8 | |
| 32 # Atom 63.9/79.0/32.1 64.0/84.8(***) | |
| 33 # | |
| 34 # (*) "Hyper-threading" in the context refers rather to cache shared | |
| 35 # among multiple cores, than to specifically Intel HTT. As vast | |
| 36 # majority of contemporary cores share cache, slower code path | |
| 37 # is common place. In other words "with-hyper-threading-off" | |
| 38 # results are presented mostly for reference purposes. | |
| 39 # | |
| 40 # (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe. | |
| 41 # | |
| 42 # (***) Less impressive improvement on Core 2 and Atom is due to slow | |
| 43 # pshufb, yet it's respectable +40%/78% improvement on Core 2 | |
| 44 # (as implied, over "hyper-threading-safe" code path). | |
