| # AES for SPARC T4.
| #
| # AES round instructions complete in 3 cycles and can be issued every
| # cycle. It means that round calculations should take 4*rounds cycles,
| # because any given round instruction depends on result of *both*
| # previous instructions:
| #
| # |0 |1 |2 |3 |4
| # |01|01|01|
| # |23|23|23|
| # |01|01|...
| # |23|...
| #
| # Provided that fxor [with IV] takes 3 cycles to complete, critical
| # path length for CBC encrypt would be 3+4*rounds, or in other words
| # it should process one byte in at least (3+4*rounds)/16 cycles. This
| # estimate doesn't account for "collateral" instructions, such as
| # fetching input from memory, xor-ing it with zero-round key and
| # storing the result. Yet, *measured* performance [for data aligned
| # at 64-bit boundary!] deviates from this equation by less than 0.5%:
| #
| # 128-bit key 192- 256-
| # CBC encrypt 2.70/2.90(*) 3.20/3.40 3.70/3.90
| # (*) numbers after slash are for
| # misaligned data.
| #
| # Out-of-order execution logic managed to fully overlap "collateral"
| # instructions with those on critical path. Amazing!
| #
| # As with Intel AES-NI, question is if it's possible to improve
| # performance of parallelizable modes by interleaving round
| # instructions. Provided round instruction latency and throughput
| # optimal interleave factor is 2. But can we expect 2x performance
| # improvement? Well, as round instructions can be issued one per
| # cycle, they don't saturate the 2-way issue pipeline and therefore
| # there is room for "collateral" calculations... Yet, 2x speed-up
| # over CBC encrypt remains unattaintable:
| #
| # 128-bit key 192- 256-
| # CBC decrypt 1.64/2.11 1.89/2.37 2.23/2.61
| # CTR 1.64/2.08(*) 1.89/2.33 2.23/2.61
| # (*) numbers after slash are for
| # misaligned data.
| #
| # Estimates based on amount of instructions under assumption that
| # round instructions are not pairable with any other instruction
| # suggest that latter is the actual case and pipeline runs
| # underutilized. It should be noted that T4 out-of-order execution
| # logic is so capable that performance gain from 2x interleave is
| # not even impressive, ~7-13% over non-interleaved code, largest
| # for 256-bit keys.
|
| # To anchor to something else, software implementation processes
| # one byte in 29 cycles with 128-bit key on same processor. Intel
| # Sandy Bridge encrypts byte in 5.07 cycles in CBC mode and decrypts
| # in 0.93, naturally with AES-NI.
