| 5 | * x86_64 BIGNUM accelerator version 0.1, December 2002. | |
| 6 | * | |
| 7 | * Implemented by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL | |
| 8 | * project. | |
| 9 | * | |
| 10 | * Rights for redistribution and usage in source and binary forms are | |
| 11 | * granted according to the OpenSSL license. Warranty of any kind is | |
| 12 | * disclaimed. | |
| 13 | * | |
| 14 | * Q. Version 0.1? It doesn't sound like Andy, he used to assign real | |
| 15 | * versions, like 1.0... | |
| 16 | * A. Well, that's because this code is basically a quick-n-dirty | |
| 17 | * proof-of-concept hack. As you can see it's implemented with | |
| 18 | * inline assembler, which means that you're bound to GCC and that | |
| 1809e858 | 19 | * there might be enough room for further improvement. |

| 21 | * Q. Why inline assembler? | |
| 1809e858 AP |
22 | * A. x86_64 features own ABI which I'm not familiar with. This is |
| 23 | * why I decided to let the compiler take care of subroutine | |
| 24 | * prologue/epilogue as well as register allocation. For reference. | |
| 25 | * Win64 implements different ABI for AMD64, different from Linux. | |

26 | * |
| 27 | * Q. How much faster does it get? | |
| 1809e858 AP |
28 | * A. 'apps/openssl speed rsa dsa' output with no-asm: |
| 29 | * | |
| 30 | * sign verify sign/s verify/s | |
| 31 | * rsa 512 bits 0.0006s 0.0001s 1683.8 18456.2 | |
| 32 | * rsa 1024 bits 0.0028s 0.0002s 356.0 6407.0 | |
| 33 | * rsa 2048 bits 0.0172s 0.0005s 58.0 1957.8 | |
| 34 | * rsa 4096 bits 0.1155s 0.0018s 8.7 555.6 | |
| 35 | * sign verify sign/s verify/s | |
| 36 | * dsa 512 bits 0.0005s 0.0006s 2100.8 1768.3 | |
| 37 | * dsa 1024 bits 0.0014s 0.0018s 692.3 559.2 | |
| 38 | * dsa 2048 bits 0.0049s 0.0061s 204.7 165.0 | |
| 39 | * | |
| 40 | * 'apps/openssl speed rsa dsa' output with this module: | |
| 41 | * | |
| 42 | * sign verify sign/s verify/s | |
| 43 | * rsa 512 bits 0.0004s 0.0000s 2767.1 33297.9 | |
| 44 | * rsa 1024 bits 0.0012s 0.0001s 867.4 14674.7 | |
| 45 | * rsa 2048 bits 0.0061s 0.0002s 164.0 5270.0 | |
| 46 | * rsa 4096 bits 0.0384s 0.0006s 26.1 1650.8 | |
| 47 | * sign verify sign/s verify/s | |
| 48 | * dsa 512 bits 0.0002s 0.0003s 4442.2 3786.3 | |
| 49 | * dsa 1024 bits 0.0005s 0.0007s 1835.1 1497.4 | |
| 50 | * dsa 2048 bits 0.0016s 0.0020s 620.4 504.6 | |
| 51 | * | |
| 52 | * For the reference. IA-32 assembler implementation performs | |
| 53 | * very much like 64-bit code compiled with no-asm on the same | |
| 54 | * machine. | |
