For further 15 @ details see http://www.openssl.org/~appro/cryptogams/. 16 @ ==================================================================== 17 18 @ AES for ARMv4 19 20 @ January 2007. 21 @ 22 @ Code uses single 1K S-box and is >2 times faster than code generated 23 @ by gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which 24 @ allows to merge logical or arithmetic operation with shift or rotate 25 @ in one instruction and emit combined result every cycle. The module 26 @ is endian-neutral. The performance is ~42 cycles/byte for 128-bit 27 @ key [on single-issue Xscale PXA250 core]. 28 29 @ May 2007. 30 @ 31 @ AES_set_[en|de]crypt_key is added. 32 33 @ July 2010. 34 @ 35 @ Rescheduling for dual-issue pipeline resulted in 12% improvement on 36 @ Cortex A8 core and ~25 cycles per byte processed with 128-bit key. 37 38 @ February 2011. 39 @ 40 @ Profiler-assisted and platform-specific optimization resulted in 16% 41 @ improvement on Cortex A8 core and ~21.5 cycles per byte. 42 43 #ifndef __KERNEL__ 44 # include "arm_arch.h" 45 #else 46 # define __ARM_ARCH__ __LINUX_ARM_ARCH__ 47
