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/.
8 # ====================================================================
9 #
10 # Version 2.1.
11 #
12 # aes-*-cbc benchmarks are improved by >70% [compared to gcc 3.3.2 on
13 # Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
14 # [you'll notice a lot of resemblance], such as compressed S-boxes
15 # in little-endian byte order, prefetch of these tables in CBC mode,
16 # as well as avoiding L1 cache aliasing between stack frame and key
17 # schedule and already mentioned tables, compressed Td4...
18 #
19 # Performance in number of cycles per processed byte for 128-bit key:
20 #
21 # ECB encrypt ECB decrypt CBC large chunk
22 # AMD64 33 41 13.0
23 # EM64T 38 59 18.6(*)
24 # Core 2 30 43 14.5(*)
25 #
26 # (*) with hyper-threading off
