| 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 | |

| 10 # AES for ARMv4 | |
| 11 | |
| 12 # January 2007. | |
| 13 # | |
| 14 # Code uses single 1K S-box and is >2 times faster than code generated | |
| 15 # by gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which | |
| 16 # allows to merge logical or arithmetic operation with shift or rotate | |
| 17 # in one instruction and emit combined result every cycle. The module | |
| 18 # is endian-neutral. The performance is ~42 cycles/byte for 128-bit | |
| 19 # key [on single-issue Xscale PXA250 core]. | |
| 20 | |
| 21 # May 2007. | |
| 22 # | |
| 23 # AES_set_[en|de]crypt_key is added. | |
| 24 | |
| 25 # July 2010. | |
| 26 # | |
| 27 # Rescheduling for dual-issue pipeline resulted in 12% improvement on | |
| 28 # Cortex A8 core and ~25 cycles per byte processed with 128-bit key. | |
| 29 | |
| 30 # February 2011. | |
| 31 # | |
| 32 # Profiler-assisted and platform-specific optimization resulted in 16% | |
| 33 # improvement on Cortex A8 core and ~21.5 cycles per byte. | |
