| c3473126 | 19 | # The module implements "4-bit" GCM GHASH function and underlying |
| d364506a AP |
20 | # single multiplication operation in GF(2^128). "4-bit" means that |
| 21 | # it uses 256 bytes per-key table [+128 bytes shared table]. GHASH | |
| 22 | # function features so called "528B" variant utilizing additional | |
| 23 | # 256+16 bytes of per-key storage [+512 bytes shared table]. | |
| 24 | # Performance results are for this streamed GHASH subroutine and are | |
| 25 | # expressed in cycles per processed byte, less is better: | |

| 53 | # Overhaul: aggregate Karatsuba post-processing, improve ILP in | |
| 54 | # reduction_alg9, increase reduction aggregate factor to 4x. As for | |
| 55 | # the latter. ghash-x86.pl discusses that it makes lesser sense to | |
| 56 | # increase aggregate factor. Then why increase here? Critical path | |
| 57 | # consists of 3 independent pclmulqdq instructions, Karatsuba post- | |
| 58 | # processing and reduction. "On top" of this we lay down aggregated | |
| 59 | # multiplication operations, triplets of independent pclmulqdq's. As | |
| 60 | # issue rate for pclmulqdq is limited, it makes lesser sense to | |
| 61 | # aggregate more multiplications than it takes to perform remaining | |
| 62 | # non-multiplication operations. 2x is near-optimal coefficient for | |
| 63 | # contemporary Intel CPUs (therefore modest improvement coefficient), | |
| 64 | # but not for Bulldozer. Latter is because logical SIMD operations | |
| 65 | # are twice as slow in comparison to Intel, so that critical path is | |
| 66 | # longer. A CPU with higher pclmulqdq issue rate would also benefit | |
| 67 | # from higher aggregate factor... | |
