| 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: | |
