9 @ ====================================================================
11 @ SHA512 block procedure for ARMv4. September 2007.
13 @ This code is ~4.5 (four and a half) times faster than code generated
14 @ by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue
15 @ Xscale PXA250 core].
17 @ July 2010.
19 @ Rescheduling for dual-issue pipeline resulted in 6% improvement on
20 @ Cortex A8 core and ~40 cycles per processed byte.
22 @ February 2011.
24 @ Profiler-assisted and platform-specific optimization resulted in 7%
25 @ improvement on Coxtex A8 core and ~38 cycles per byte.
27 @ March 2011.
29 @ Add NEON implementation. On Cortex A8 it was measured to process
30 @ one byte in 23.3 cycles or ~60% faster than integer-only code.
32 @ August 2012.
34 @ Improve NEON performance by 12% on Snapdragon S4. In absolute
35 @ terms it's 22.6 cycles per byte, which is disappointing result.
36 @ Technical writers asserted that 3-way S4 pipeline can sustain
37 @ multiple NEON instructions per cycle, but dual NEON issue could
38 @ not be observed, see http://www.openssl.org/~appro/Snapdragon-S4.html
39 @ for further details. On side note Cortex-A15 processes one byte in
40 @ 16 cycles.
42 @ Byte order [in]dependence. =========================================
44 @ Originally caller was expected to maintain specific *dword* order in
45 @ h[0-7], namely with most significant dword at *lower* address, which
46 @ was reflected in below two parameters as 0 and 4. Now caller is
47 @ expected to maintain native byte order for whole 64-bit values.
