# Keccak-1600 for x86 MMX.
|
|
#
|
|
# June 2017.
|
|
#
|
|
# Below code is KECCAK_2X implementation (see sha/keccak1600.c) with
|
|
# C[5] held in register bank and D[5] offloaded to memory. Though
|
|
# instead of actually unrolling the loop pair-wise I simply flip
|
|
# pointers to T[][] and A[][] and the end of round. Since number of
|
|
# rounds is even, last round writes to A[][] and everything works out.
|
|
# It's argued that MMX is the only code path meaningful to implement
|
|
# for x86. This is because non-MMX-capable processors is an extinct
|
|
# breed, and they as well can lurk executing compiler-generated code.
|
|
# For reference gcc-5.x-generated KECCAK_2X code takes 89 cycles per
|
|
# processed byte on Pentium. Which is fair result. But older compilers
|
|
# produce worse code. On the other hand one can wonder why not 128-bit
|
|
# SSE2? Well, SSE2 won't provide double improvement, rather far from
|
|
# that, if any at all on some processors, because it will take extra
|
|
# permutations and inter-bank data transfers. Besides, contemporary
|
|
# CPUs are better off executing 64-bit code, and it makes lesser sense
|
|
# to invest into fancy 32-bit code. And the decision doesn't seem to
|
|
# be inadequate, if one compares below results to "64-bit platforms in
|
|
# 32-bit mode" SIMD data points available at
|
|
# http://keccak.noekeon.org/sw_performance.html.
