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.

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...

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.
