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. | ||
