16 @ ====================================================================
18 @ SHA512 block procedure for ARMv4. September 2007.
20 @ This code is ~4.5 (four and a half) times faster than code generated
21 @ by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue
22 @ Xscale PXA250 core].
24 @ July 2010.
26 @ Rescheduling for dual-issue pipeline resulted in 6% improvement on
27 @ Cortex A8 core and ~40 cycles per processed byte.
29 @ February 2011.
31 @ Profiler-assisted and platform-specific optimization resulted in 7%
32 @ improvement on Coxtex A8 core and ~38 cycles per byte.
34 @ March 2011.
36 @ Add NEON implementation. On Cortex A8 it was measured to process
37 @ one byte in 23.3 cycles or ~60% faster than integer-only code.
39 @ August 2012.
41 @ Improve NEON performance by 12% on Snapdragon S4. In absolute
42 @ terms it's 22.6 cycles per byte, which is disappointing result.
43 @ Technical writers asserted that 3-way S4 pipeline can sustain
44 @ multiple NEON instructions per cycle, but dual NEON issue could
45 @ not be observed, see https://www.openssl.org/~appro/Snapdragon-S4.html
46 @ for further details. On side note Cortex-A15 processes one byte in
47 @ 16 cycles.
49 @ Byte order [in]dependence. =========================================
51 @ Originally caller was expected to maintain specific *dword* order in
52 @ h[0-7], namely with most significant dword at *lower* address, which
53 @ was reflected in below two parameters as 0 and 4. Now caller is
54 @ expected to maintain native byte order for whole 64-bit values.
