Collection of various vectorised functions. Currently supported functions:
- Bitwise - various bitwise operations over arrays of 64-bit unsigned integers or bytes
- Popcnt - count number of set bits in arrays of 64-bit unsigned integers or bytes
- Memclr - clear arrays of 64-bit unsigned integers or bytes
- Memcpy - copy arrays of 64-bit unsigned integers or bytes
- Memset - fill arrays of 64-bit unsigned integers or bytes
- Memequal - check equality of arrays of 64-bit unsigned integers or bytes
- Hamming - calculate Hamming distance of 64-bit unsigned integers or bytes
- SkipLine - find end of line in multi-line bytes slice
- Indexbyte - find position of given byte in bytes slice
- Indextoken - find position of next token in bytes slice
- Xorkey - apply XOR operation over data using given key
- ...
Currently supported arch and instructions sets:
- AMD64
- SSE2-SSE4.2
- AVX2
- AVX512
All AMD64 solutions supports fallback mode - checks at init supported instructions sets and choose the optimal:
- use AVX512 if possible
- use AVX2 if possible and not possible AVX512
- use SSE2-SSE4.2 if not possible AVX2/AVX512
- use generic (pure Go) if not possible SSE2-SSE4.2
