| # 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. |

| $::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. |
