| # SHA512 block transform for x86. September 2007. |
| # |
| # Performance in clock cycles per processed byte (less is better): |
| # |
| # Pentium PIII P4 AMD K8 Core2 |
| # gcc 100 75 116 54 66 |
| # icc 97 77 95 55 57 |
| # x86 asm 61 56 82 36 40 |
| # SSE2 asm - - 38 24 20 |
| # x86_64 asm(*) - - 30 10.0 10.5 |

| # (*) x86_64 assembler performance is presented for reference |
| # purposes. |
| # |
| # IALU code-path is optimized for elder Pentiums. On vanilla Pentium |
| # performance improvement over compiler generated code reaches ~60%, |
| # while on PIII - ~35%. On newer ยต-archs improvement varies from 15% |
| # to 50%, but it's less important as they are expected to execute SSE2 |
| # code-path, which is commonly ~2-3x faster [than compiler generated |
| # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even |
| # though it does not use 128-bit operations. The latter means that |
| # SSE2-aware kernel is no longer required to execute the code. Another |
| # difference is that new code optimizes amount of writes, but at the |
| # cost of increased data cache "footprint" by 1/2KB. |
