# The module implements "4-bit" GCM GHASH function and underlying
|
|
# single multiplication operation in GF(2^128). "4-bit" means that
|
|
# it uses 256 bytes per-key table [+128 bytes shared table]. GHASH
|
|
# function features so called "528B" variant utilizing additional
|
|
# 256+16 bytes of per-key storage [+512 bytes shared table].
|
|
# Performance results are for this streamed GHASH subroutine and are
|
|
# expressed in cycles per processed byte, less is better:
|
|
#
|
|
# gcc 3.4.x(*) assembler
|
|
#
|
|
# P4 28.6 14.0 +100%
|
|
# Opteron 19.3 7.7 +150%
|
|
# Core2 17.8 8.1(**) +120%
|
|
# Atom 31.6 16.8 +88%
|
|
# VIA Nano 21.8 10.1 +115%
|
|
#
|
|
# (*) comparison is not completely fair, because C results are
|
|
# for vanilla "256B" implementation, while assembler results
|
|
# are for "528B";-)
|
|
# (**) it's mystery [to me] why Core2 result is not same as for
|
|
# Opteron;

|
|
# Overhaul: aggregate Karatsuba post-processing, improve ILP in
|
|
# reduction_alg9, increase reduction aggregate factor to 4x. As for
|
|
# the latter. ghash-x86.pl discusses that it makes lesser sense to
|
|
# increase aggregate factor. Then why increase here? Critical path
|
|
# consists of 3 independent pclmulqdq instructions, Karatsuba post-
|
|
# processing and reduction. "On top" of this we lay down aggregated
|
|
# multiplication operations, triplets of independent pclmulqdq's. As
|
|
# issue rate for pclmulqdq is limited, it makes lesser sense to
|
|
# aggregate more multiplications than it takes to perform remaining
|
|
# non-multiplication operations. 2x is near-optimal coefficient for
|
|
# contemporary Intel CPUs (therefore modest improvement coefficient),
|
|
# but not for Bulldozer. Latter is because logical SIMD operations
|
|
# are twice as slow in comparison to Intel, so that critical path is
|
|
# longer. A CPU with higher pclmulqdq issue rate would also benefit
|
|
# from higher aggregate factor...
|
|

|
|
# Westmere 1.78(+13%)
|
|
# Sandy Bridge 1.80(+8%)
|
|
# Ivy Bridge 1.80(+7%)
|
|
# Haswell 0.55(+93%) (if system doesn't support AVX)
|
|
# Broadwell 0.45(+110%)(if system doesn't support AVX)
|
|
# Skylake 0.44(+110%)(if system doesn't support AVX)

|
|
# ... 8x aggregate factor AVX code path is using reduction algorithm
|
|
# suggested by Shay Gueron[1]. Even though contemporary AVX-capable
|
|
# CPUs such as Sandy and Ivy Bridge can execute it, the code performs
|
|
# sub-optimally in comparison to above mentioned version. But thanks
|
|
# to Ilya Albrekht and Max Locktyukhin of Intel Corp. we knew that
|
|
# it performs in 0.41 cycles per byte on Haswell processor, in
|
|
# 0.29 on Broadwell, and in 0.36 on Skylake.
|
|
#
|
|
# Knights Landing achieves 1.09 cpb.
