# SHA512 block procedure for ARMv4. September 2007.
|
|
|
|
# This code is ~4.5 (four and a half) times faster than code generated
|
|
# by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue
|
|
# Xscale PXA250 core].
|
|
#
|
|
# July 2010.
|
|
#
|
|
# Rescheduling for dual-issue pipeline resulted in 6% improvement on
|
|
# Cortex A8 core and ~40 cycles per processed byte.
|
|
|
|
# Byte order [in]dependence. =========================================
|
|
#
|
|
# Caller is expected to maintain specific *dword* order in h[0-7],
|
|
# namely with most significant dword at *lower* address, which is
|
|
# reflected in below two parameters. *Byte* order within these dwords
|
|
# in turn is whatever *native* byte order on current platform.
