# Camellia for SPARC T4.
|
||||
#
|
||||
# As with AES below results [for aligned data] are virtually identical
|
||||
# to critical path lenths for 3-cycle instruction latency:
|
||||
#
|
||||
# 128-bit key 192/256-
|
||||
# CBC encrypt 4.14/4.21(*) 5.46/5.52
|
||||
# (*) numbers after slash are for
|
||||
# misaligned data.
|
||||
#
|
||||
# As with Intel AES-NI, question is if it's possible to improve
|
||||
# performance of parallelizeable modes by interleaving round
|
||||
# instructions. In Camellia every instruction is dependent on
|
||||
# previous, which means that there is place for 2 additional ones
|
||||
# in between two dependent. Can we expect 3x performance improvement?
|
||||
# At least one can argue that it should be possible to break 2x
|
||||
# barrier... For some reason not even 2x appears to be possible:
|
||||
#
|
||||
# 128-bit key 192/256-
|
||||
# CBC decrypt 2.21/2.74 2.99/3.40
|
||||
# CTR 2.15/2.68(*) 2.93/3.34
|
||||
# (*) numbers after slash are for
|
||||
# misaligned data.
|
||||
#
|
||||
# This is for 2x interleave. But compared to 1x interleave CBC decrypt
|
||||
# improved by ... 0% for 128-bit key, and 11% for 192/256-bit one.
|
||||
# So that out-of-order execution logic can take non-interleaved code
|
||||
# to 1.87x, but can't take 2x interleaved one any further. There
|
||||
# surely is some explanation... As result 3x interleave was not even
|
||||
# attempted. Instead an effort was made to share specific modes
|
||||
# implementations with AES module (therefore sparct4_modes.pl).
|
||||
#
|
||||
# To anchor to something else, software C implementation processes
|
||||
# one byte in 38 cycles with 128-bit key on same processor.

|

* reduces amount of instructions per setup round and code increase is
|
||||
* justifiable. In block functions on the other hand only inner loops
|
||||
* are unrolled, as full unroll gives only nominal performance boost,
|
||||
* while code size grows 4 or 7 times. Also, unlike previous versions
|
||||
* this one "encourages" compiler to keep intermediate variables in
|
||||
* registers, which should give better "all round" results, in other
|
||||
* words reasonable performance even with not so modern compilers.
