10 | # SHA512 block procedure for ARMv4. September 2007. | ||
11 | |||
12 | # This code is ~4.5 (four and a half) times faster than code generated | ||
13 | # by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue | ||
14 | # Xscale PXA250 core]. | ||
15 | # | ||
16 | # July 2010. | ||
17 | # | ||
18 | # Rescheduling for dual-issue pipeline resulted in 6% improvement on | ||
19 | # Cortex A8 core and ~40 cycles per processed byte. | ||
20 | |||
21 | # Byte order [in]dependence. ========================================= | ||
22 | # | ||
23 | # Caller is expected to maintain specific *dword* order in h[0-7], | ||
24 | # namely with most significant dword at *lower* address, which is | ||
25 | # reflected in below two parameters. *Byte* order within these dwords | ||
26 | # in turn is whatever *native* byte order on current platform. | ||
