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