| 18 | # Approach - We want to reload constants as we have plenty of spare ASIMD slots around crypto units for loading | |
| 19 | # Unroll x8 in main loop, main loop to act on 8 16B blocks per iteration, and then do modulo of the accumulated | |
| 20 | # intermediate hashesfrom the 8 blocks. | |

| 120 | # Do 128b karatsuba polynomial multiplication on block | |
| 121 | # We only have 64b->128b polynomial multipliers, naively that means we need to do 4 64b multiplies to generate a 128b | |
| 122 | # | |
| 123 | # multiplication: | |
| 124 | # Pmull(A,B) == (Pmull(Ah,Bh)<<128 | Pmull(Al,Bl)) ^ (Pmull(Ah,Bl) ^ Pmull(Al,Bh))<<64 | |
| 125 | # | |

| 129 | # There is some complication here because the bit order of GHASH's PMULL is reversed compared to elsewhere, so we are | |
| 130 | # multiplying with "twisted" powers of H | |
| 131 | # | |
| 132 | # Note: We can PMULL directly into the acc_x in first GHASH of the loop | |
| 133 | # Note: For scheduling big cores we want to split the processing to happen over two loop iterations - otherwise the critical | |
| 134 | # path latency dominates the performance | |
