9 # sha256/512_block procedure for x86_64.
10 #
11 # 40% improvement over compiler-generated code on Opteron. On EM64T
12 # sha256 was observed to run >80% faster and sha512 - >40%. No magical
13 # tricks, just straight implementation... I really wonder why gcc
14 # [being armed with inline assembler] fails to generate as fast code.
15 # The only thing which is cool about this module is that it's very
16 # same instruction sequence used for both SHA-256 and SHA-512. In
17 # former case the instructions operate on 32-bit operands, while in
18 # latter - on 64-bit ones. All I had to do is to get one flavor right,
19 # the other one passed the test right away:-)
20 #
21 # sha256_block runs in ~1005 cycles on Opteron, which gives you
22 # asymptotic performance of 64*1000/1005=63.7MBps times CPU clock
23 # frequency in GHz. sha512_block runs in ~1275 cycles, which results
24 # in 128*1000/1275=100MBps per GHz. Is there room for improvement?
25 # Well, if you compare it to IA-64 implementation, which maintains
26 # X[16] in register bank[!], tends to 4 instructions per CPU clock
27 # cycle and runs in 1003 cycles, 1275 is very good result for 3-way
28 # issue Opteron pipeline and X[16] maintained in memory. So that *if*
29 # there is a way to improve it, *then* the only way would be to try to
30 # offload X[16] updates to SSE unit, but that would require "deeper"
31 # loop unroll, which in turn would naturally cause size blow-up, not
32 # to mention increased complexity! And once again, only *if* it's
33 # actually possible to noticeably improve overall ILP, instruction
34 # level parallelism, on a given CPU implementation in this case.
35 #
36 # Special note on Intel EM64T. While Opteron CPU exhibits perfect
37 # perfromance ratio of 1.5 between 64- and 32-bit flavors [see above],
38 # [currently available] EM64T CPUs apparently are far from it. On the
39 # contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit
40 # sha256_block:-( This is presumably because 64-bit shifts/rotates
41 # apparently are not atomic instructions, but implemented in microcode.
42 #
43 # May 2012.
44 #
45 # Optimization including one of Pavel Semjanov's ideas, alternative
46 # Maj, resulted in >=5% improvement on most CPUs, +20% SHA256 and
47 # unfortunately -2% SHA512 on P4 [which nobody should care about
48 # that much].
49 #
50 # June 2012.
51 #
52 # Add SIMD code paths, see below for improvement coefficients. SSSE3
53 # code path was not attempted for SHA512, because improvement is not
54 # estimated to be high enough, noticeably less than 9%, to justify
55 # the effort, not on pre-AVX processors. [Obviously with exclusion
56 # for VIA Nano, but it has SHA512 instruction that is faster and
57 # should be used instead.] For reference, corresponding estimated
58 # upper limit for improvement for SSSE3 SHA256 is 28%. The fact that
59 # higher coefficients are observed on VIA Nano and Bulldozer has more
60 # to do with specifics of their architecture [which is topic for
61 # separate discussion].
62 #
63 # November 2012.
64 #
65 # Add AVX2 code path. Two consecutive input blocks are loaded to
66 # 256-bit %ymm registers, with data from first block to least
67 # significant 128-bit halves and data from second to most significant.
68 # The data is then processed with same SIMD instruction sequence as
69 # for AVX, but with %ymm as operands. Side effect is increased stack
70 # frame, 448 additional bytes in SHA256 and 1152 in SHA512, and 1.2KB
71 # code size increase.
72 #
73 # March 2014.
74 #
75 # Add support for Intel SHA Extensions.
