# 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:

# 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%:

# 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

# Estimates based on amount of instructions under assumption that

# round instructions are not pairable with any other instruction
|

# 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
