# [Endian-neutral] AES for C64x+.
#
# Even though SPLOOPs are scheduled for 13 cycles, and thus expected
# performance is ~8.5 cycles per byte processed with 128-bit key,
# measured performance turned to be ~10 cycles per byte. Discrepancy
# must be caused by limitations of L1D memory banking(*), see SPRU871
# TI publication for further details. If any consolation it's still
# ~20% faster than TI's linear assembly module anyway... Compared to
# aes_core.c compiled with cl6x 6.0 with -mv6400+ -o2 options this
# code is 3.75x faster and almost 3x smaller (tables included).
#
# (*)	This means that there might be subtle correlation between data
#	and timing and one can wonder if it can be ... attacked:-(
#	On the other hand this also means that *if* one chooses to
#	implement *4* T-tables variant [instead of 1 T-table as in
#	this implementation, or in addition to], then one ought to
#	*interleave* them. Even though it complicates addressing,
#	references to interleaved tables would be guaranteed not to
#	clash. I reckon that it should be possible to break 8 cycles
#	per byte "barrier," i.e. improve by ~20%, naturally at the
#	cost of 8x increased pressure on L1D. 8x because you'd have
#	to interleave both Te and Td tables...
