11 # You might fail to appreciate this module performance from the first
12 # try. If compared to "vanilla" linux-ia32-icc target, i.e. considered
13 # to be *the* best Intel C compiler without -KPIC, performance appears
14 # to be virtually identical... But try to re-configure with shared
15 # library support... Aha! Intel compiler "suddenly" lags behind by 30%
16 # [on P4, more on others]:-) And if compared to position-independent
17 # code generated by GNU C, this code performs *more* than *twice* as
18 # fast! Yes, all this buzz about PIC means that unlike other hand-
19 # coded implementations, this one was explicitly designed to be safe
20 # to use even in shared library context... This also means that this
21 # code isn't necessarily absolutely fastest "ever," because in order
22 # to achieve position independence an extra register has to be
23 # off-loaded to stack, which affects the benchmark result.
25 # Special note about instruction choice. Do you recall RC4_INT code
26 # performing poorly on P4? It might be the time to figure out why.
27 # RC4_INT code implies effective address calculations in base+offset*4
28 # form. Trouble is that it seems that offset scaling turned to be
29 # critical path... At least eliminating scaling resulted in 2.8x RC4
30 # performance improvement [as you might recall]. As AES code is hungry
31 # for scaling too, I [try to] avoid the latter by favoring off-by-2
32 # shifts and masking the result with 0xFF<<2 instead of "boring" 0xFF.
34 # As was shown by Dean Gaudet <dean@arctic.org>, the above note turned
35 # void. Performance improvement with off-by-2 shifts was observed on
36 # intermediate implementation, which was spilling yet another register
37 # to stack... Final offset*4 code below runs just a tad faster on P4,
38 # but exhibits up to 10% improvement on other cores.
40 # Second version is "monolithic" replacement for aes_core.c, which in
41 # addition to AES_[de|en]crypt implements AES_set_[de|en]cryption_key.
42 # This made it possible to implement little-endian variant of the
43 # algorithm without modifying the base C code. Motivating factor for
44 # the undertaken effort was that it appeared that in tight IA-32
45 # register window little-endian flavor could achieve slightly higher
46 # Instruction Level Parallelism, and it indeed resulted in up to 15%
47 # better performance on most recent µ-archs...
49 # Third version adds AES_cbc_encrypt implementation, which resulted in
50 # up to 40% performance imrovement of CBC benchmark results. 40% was
51 # observed on P4 core, where "overall" imrovement coefficient, i.e. if
52 # compared to PIC generated by GCC and in CBC mode, was observed to be
53 # as large as 4x:-) CBC performance is virtually identical to ECB now
54 # and on some platforms even better, e.g. 17.6 "small" cycles/byte on
55 # Opteron, because certain function prologues and epilogues are
56 # effectively taken out of the loop...
58 # Version 3.2 implements compressed tables and prefetch of these tables
59 # in CBC[!] mode. Former means that 3/4 of table references are now
60 # misaligned, which unfortunately has negative impact on elder IA-32
61 # implementations, Pentium suffered 30% penalty, PIII - 10%.
63 # Version 3.3 avoids L1 cache aliasing between stack frame and
64 # S-boxes, and 3.4 - L1 cache aliasing even between key schedule. The
65 # latter is achieved by copying the key schedule to controlled place in
66 # stack. This unfortunately has rather strong impact on small block CBC
67 # performance, ~2x deterioration on 16-byte block if compared to 3.3.
69 # Version 3.5 checks if there is L1 cache aliasing between user-supplied
70 # key schedule and S-boxes and abstains from copying the former if
71 # there is no. This allows end-user to consciously retain small block
72 # performance by aligning key schedule in specific manner.
74 # Version 3.6 compresses Td4 to 256 bytes and prefetches it in ECB.
76 # Current ECB performance numbers for 128-bit key in CPU cycles per
77 # processed byte [measure commonly used by AES benchmarkers] are:
79 # small footprint fully unrolled
85 # Version 3.7 reimplements outer rounds as "compact." Meaning that
86 # first and last rounds reference compact 256 bytes S-box. This means
87 # that first round consumes a lot more CPU cycles and that encrypt
88 # and decrypt performance becomes asymmetric. Encrypt performance
89 # drops by 10-12%, while decrypt - by 20-25%:-( 256 bytes S-box is
90 # aggressively pre-fetched.
92 # Version 4.0 effectively rolls back to 3.6 and instead implements
93 # additional set of functions, _[x86|mmx]_AES_[en|de]crypt_compact,
94 # which use exclusively 256 byte S-box. These functions are to be
95 # called in modes not concealing plain text, such as ECB, or when
96 # we're asked to process smaller amount of data [or unconditionally
97 # on hyper-threading CPU]. Currently it's called unconditionally from
98 # AES_[en|de]crypt, which affects all modes, but CBC. CBC routine
99 # still needs to be modified to switch between slower and faster
100 # mode when appropriate... But in either case benchmark landscape
101 # changes dramatically and below numbers are CPU cycles per processed
102 # byte for 128-bit key.

503 # Why not xmm registers? Short answer. It was actually tested and
504 # was not any faster, but *contrary*, most notably on Intel CPUs.
505 # Longer answer. Main advantage of using mm registers is that movd
506 # latency is lower, especially on Intel P4. While arithmetic
507 # instructions are twice as many, they can be scheduled every cycle
508 # and not every second one when they are operating on xmm register,
509 # so that "arithmetic throughput" remains virtually the same. And
510 # finally the code can be executed even on elder MMX-only CPUs:-)
