MLnoCS vs LX4Cnh

Algorithm Maximum bits One multiplication
LX4Cnh 128+ × 128+ less than ~ 4.3 ns == 0.0000000043 sec
MLnoCS 128+ × 16 (*[1] 32) less than ~ 0.31 ns == 0.00000000031 sec
LX4Cnh optimized*[2] 128+ × 128+ *[2] less than ~ 0.86 ns == 0.00000000086 sec
  • *[1] - theoretically up to 128 x 32 with some correction.
  • *[2] - The actual calculation using LX4Cnh can be a bit optimized such for FNV1a-128 implementation (find it in my repo):

(1 ns == 0.000000001 sec)

Where is this used?

.NET implementation

128-bit numbers (full range, 128 × 128) NuGet package

LX4Cnh class provides several ways of setting and getting numbers by using uint, ulong, or bytes array. Just play with available Unit-Tests and Speed-Tests.

For example, using ulong (UInt64)
//   0x4BD4823ECC5D03EB19E07DB8FFD5DABE
// × 0x1D05906000069ABC40A30C07A70906D1

ulong high = LX4Cnh.Multiply
    0x4BD4823ECC5D03EB, 0x19E07DB8FFD5DABE,
    0x1D05906000069ABC, 0x40A30C07A70906D1,
    out ulong low
//          high            low
//     ________________|_______________
// = 0xACBBE8EAB60C77E249B25D708366091E
