| 10 # SHA512 block transform for x86. September 2007. | |
| 11 # | |
| 12 # Performance in clock cycles per processed byte (less is better): | |
| 13 # | |
| 14 # Pentium PIII P4 AMD K8 Core2 | |
| 15 # gcc 100 75 116 54 66 | |
| 16 # icc 97 77 95 55 57 | |
| 17 # x86 asm 61 56 82 36 40 | |
| 18 # SSE2 asm - - 38 24 20 | |
| 19 # x86_64 asm(*) - - 30 10.0 10.5 | |
| 20 # | |
| 21 # (*) x86_64 assembler performance is presented for reference | |
| 22 # purposes. | |
| 23 # | |
| 24 # IALU code-path is optimized for elder Pentiums. On vanilla Pentium | |
| 25 # performance improvement over compiler generated code reaches ~60%, | |
| 26 # while on PIII - ~35%. On newer µ-archs improvement varies from 15% | |
| 27 # to 50%, but it's less important as they are expected to execute SSE2 | |
| 28 # code-path, which is commonly ~2-3x faster [than compiler generated | |
| 29 # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even | |
| 30 # though it does not use 128-bit operations. The latter means that | |
| 31 # SSE2-aware kernel is no longer required to execute the code. Another | |
| 32 # difference is that new code optimizes amount of writes, but at the | |
| 33 # cost of increased data cache "footprint" by 1/2KB. | |
