Motivation

The goal of this project is to take advantages of the SMID (Single Instruction Multiple Data) CPU extension to perform 128/256/512 bits wide operation per CPU cycle.
This library uses the following extension: AVX2, AVX512, Neon, SVE. The operation are grouped in the following packages:

• bitewise: bitwise operations
• lut: lookup operations
• blas: basic linear algebra operations
• bits: bitset/masking/packing/unpacking operations

Usage

Bitwise operation:

    out := make([]uint64, 8)
    v1 := []uint64{1, 2, 3, 4, 5, 6, 7, 8}
    v2 := []uint64{1, 7, 3, 4, 3, 6, 7, 2}
    bitwise.Uint64s(out).And(v1, v2)
