\ No newline at end of file + +@ ==================================================================== +@ Written by Andy Polyakov <appro@openssl.org> for the OpenSSL +@ project. The module is, however, dual licensed under OpenSSL and +@ CRYPTOGAMS licenses depending on where you obtain it. For further +@ details see http://www.openssl.org/~appro/cryptogams/. +@ ==================================================================== + +@ AES for ARMv4 + +@ January 2007. +@ +@ Code uses single 1K S-box and is >2 times faster than code generated +@ by gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which +@ allows to merge logical or arithmetic operation with shift or rotate +@ in one instruction and emit combined result every cycle. The module +@ is endian-neutral. The performance is ~42 cycles/byte for 128-bit +@ key [on single-issue Xscale PXA250 core]. + +@ May 2007. +@ +@ AES_set_[en|de]crypt_key is added. + +@ July 2010. +@ +@ Rescheduling for dual-issue pipeline resulted in 12% improvement on +@ Cortex A8 core and ~25 cycles per byte processed with 128-bit key. + +@ February 2011. +@ +@ Profiler-assisted and platform-specific optimization resulted in 16% +@ improvement on Cortex A8 core and ~21.5 cycles per byte. + +#ifndef __KERNEL__ +# include "arm_arch.h" +#else +# define __ARM_ARCH__ __LINUX_ARM_ARCH__ +#endif + +.text +#if __ARM_ARCH__<7
