# Keccak-1600 for ARMv4.
|
||
|
|
#
|
||
|
|
# June 2017.
|
||
|
|
#
|
||
|
|
# Non-NEON code is KECCAK_1X variant (see sha/keccak1600.c) with bit
|
||
|
|
# interleaving. How does it compare to Keccak Code Package? It's as
|
||
|
|
# fast, but several times smaller, and is endian- and ISA-neutral. ISA
|
||
|
|
# neutrality means that minimum ISA requirement is ARMv4, yet it can
|
||
|
|
# be assembled even as Thumb-2. NEON code path is KECCAK_1X_ALT with
|
||
|
|
# register layout taken from Keccak Code Package. It's also as fast,
|
||
|
|
# in fact faster by 10-15% on some processors, and endian-neutral.
|
||
|
|
#
|
||
|
|
# August 2017.
|
||
|
|
#
|
||
|
|
# Switch to KECCAK_2X variant for non-NEON code and merge almost 1/2
|
||
|
|
# of rotate instructions with logical ones. This resulted in ~10%
|
||
|
|
# improvement on most processors. Switch to KECCAK_2X effectively
|
||
|
|
# minimizes re-loads from temporary storage, and merged rotates just
|
||
|
|
# eliminate corresponding instructions. As for latter. When examining
|
||
|
|
# code you'll notice commented ror instructions. These are eliminated
|
||
|
|
# ones, and you should trace destination register below to see what's
|
||
|
|
# going on. Just in case, why not all rotates are eliminated. Trouble
|
||
|
|
# is that you have operations that require both inputs to be rotated,
|
||
|
|
# e.g. 'eor a,b>>>x,c>>>y'. This conundrum is resolved by using
|
||
|
|
# 'eor a,b,c>>>(x-y)' and then merge-rotating 'a' in next operation
|
||
|
|
# that takes 'a' as input. And thing is that this next operation can
|
||
|
|
# be in next round. It's totally possible to "carry" rotate "factors"
|
||
|
|
# to the next round, but it makes code more complex. And the last word
|
||
|
|
# is the keyword, i.e. "almost 1/2" is kind of complexity cap [for the
|
||
|
|
# time being]...
|
||
|
|
#
|
||
|
|
# Reduce per-round instruction count in Thumb-2 case by 16%. This is
|
||
|
|
# achieved by folding ldr/str pairs to their double-word counterparts.
|
||
|
|
# Theoretically this should have improved performance on single-issue
|
||
|
|
# cores, such as Cortex-A5/A7, by 19%. Reality is a bit different, as
|
||
|
|
# usual...
