| # Do 128b karatsuba polynomial multiplication on block |
| # We only have 64b->128b polynomial multipliers, naively that means we need to do 4 64b multiplies to generate a 128b |
| # |
| # multiplication: |
| # Pmull(A,B) == (Pmull(Ah,Bh)<<128 | Pmull(Al,Bl)) ^ (Pmull(Ah,Bl) ^ Pmull(Al,Bh))<<64 |
| # |
| # The idea behind Karatsuba multiplication is that we can do just 3 64b multiplies: |

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