# 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 parallelizeable 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.

$::evp=1; # if $evp is set to 0, script generates module with
# AES_[en|de]crypt, AES_set_[en|de]crypt_key and AES_cbc_encrypt entry
# points. These however are not fully compatible with openssl/aes.h,
# because they expect AES_KEY to be aligned at 64-bit boundary. When
# used through EVP, alignment is arranged at EVP layer. Second thing
# that is arranged by EVP is at least 32-bit alignment of IV.
