| 16 | # sha256/512_block procedure for x86_64. |
| 17 | # |
| 18 | # 40% improvement over compiler-generated code on Opteron. On EM64T |
| 19 | # sha256 was observed to run >80% faster and sha512 - >40%. No magical |
| 20 | # tricks, just straight implementation... I really wonder why gcc |
| 21 | # [being armed with inline assembler] fails to generate as fast code. |
| 22 | # The only thing which is cool about this module is that it's very |
| 23 | # same instruction sequence used for both SHA-256 and SHA-512. In |
| 24 | # former case the instructions operate on 32-bit operands, while in |
| 25 | # latter - on 64-bit ones. All I had to do is to get one flavor right, |
| 26 | # the other one passed the test right away:-) |
| 27 | # |
| 28 | # sha256_block runs in ~1005 cycles on Opteron, which gives you |
| 29 | # asymptotic performance of 64*1000/1005=63.7MBps times CPU clock |
| 30 | # frequency in GHz. sha512_block runs in ~1275 cycles, which results |
| 31 | # in 128*1000/1275=100MBps per GHz. Is there room for improvement? |
| 32 | # Well, if you compare it to IA-64 implementation, which maintains |
| 33 | # X[16] in register bank[!], tends to 4 instructions per CPU clock |
| 34 | # cycle and runs in 1003 cycles, 1275 is very good result for 3-way |
| 35 | # issue Opteron pipeline and X[16] maintained in memory. So that *if* |
| 36 | # there is a way to improve it, *then* the only way would be to try to |
| 37 | # offload X[16] updates to SSE unit, but that would require "deeper" |
| 38 | # loop unroll, which in turn would naturally cause size blow-up, not |
| 39 | # to mention increased complexity! And once again, only *if* it's |
| 40 | # actually possible to noticeably improve overall ILP, instruction |
| 41 | # level parallelism, on a given CPU implementation in this case. |
| 42 | # |
| 43 | # Special note on Intel EM64T. While Opteron CPU exhibits perfect |
Robert Sloan | a94fe05 | 2017-02-21 08:49:28 -0800 | [diff] [blame] | 44 | # performance ratio of 1.5 between 64- and 32-bit flavors [see above], |
Adam Langley | d9e397b | 2015-01-22 14:27:53 -0800 | [diff] [blame] | 45 | # [currently available] EM64T CPUs apparently are far from it. On the |
| 46 | # contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit |
| 47 | # sha256_block:-( This is presumably because 64-bit shifts/rotates |
| 48 | # apparently are not atomic instructions, but implemented in microcode. |
| 49 | # |
| 50 | # May 2012. |
| 51 | # |
| 52 | # Optimization including one of Pavel Semjanov's ideas, alternative |
| 53 | # Maj, resulted in >=5% improvement on most CPUs, +20% SHA256 and |
| 54 | # unfortunately -2% SHA512 on P4 [which nobody should care about |
| 55 | # that much]. |
| 56 | # |
| 57 | # June 2012. |
| 58 | # |
| 59 | # Add SIMD code paths, see below for improvement coefficients. SSSE3 |
| 60 | # code path was not attempted for SHA512, because improvement is not |
| 61 | # estimated to be high enough, noticeably less than 9%, to justify |
| 62 | # the effort, not on pre-AVX processors. [Obviously with exclusion |
| 63 | # for VIA Nano, but it has SHA512 instruction that is faster and |
| 64 | # should be used instead.] For reference, corresponding estimated |
| 65 | # upper limit for improvement for SSSE3 SHA256 is 28%. The fact that |
| 66 | # higher coefficients are observed on VIA Nano and Bulldozer has more |
| 67 | # to do with specifics of their architecture [which is topic for |
| 68 | # separate discussion]. |
| 69 | # |
| 70 | # November 2012. |
| 71 | # |
| 72 | # Add AVX2 code path. Two consecutive input blocks are loaded to |
| 73 | # 256-bit %ymm registers, with data from first block to least |
| 74 | # significant 128-bit halves and data from second to most significant. |
| 75 | # The data is then processed with same SIMD instruction sequence as |
| 76 | # for AVX, but with %ymm as operands. Side effect is increased stack |
| 77 | # frame, 448 additional bytes in SHA256 and 1152 in SHA512, and 1.2KB |
| 78 | # code size increase. |
| 79 | # |
| 80 | # March 2014. |
| 81 | # |
| 82 | # Add support for Intel SHA Extensions. |
