Overview

Package archsimd provides access to architecture-specific SIMD operations.

This is a low-level package that exposes hardware-specific functionality. It currently supports AMD64.

This package is experimental, and not subject to the Go 1 compatibility promise. It only exists when building with the GOEXPERIMENT=simd environment variable set.

Vector types and operations

Vector types are defined as structs, such as Int8x16 and Float64x8, corresponding to the hardware's vector registers. On AMD64, 128-, 256-, and 512-bit vectors are supported.

Mask types are defined similarly, such as Mask8x16, and are represented as opaque types, handling the differences in the underlying representations. A mask can be converted to/from the corresponding integer vector type, or to/from a bitmask.

Operations are mostly defined as methods on the vector types. Most of them are compiler intrinsics and correspond directly to hardware instructions.

Common operations include:

  • Load/Store: Load a vector from memory or store a vector to memory.
  • Arithmetic: Add, Sub, Mul, etc.
  • Bitwise: And, Or, Xor, etc.
  • Comparison: Equal, Greater, etc., which produce a mask.
  • Conversion: Convert between different vector types.
  • Field selection and rearrangement: GetElem, Permute, etc.
  • Masking: Masked, Merge.

The compiler recognizes certain patterns of operations and may optimize them to more performant instructions. For example, on AVX512, an Add operation followed by Masked may be optimized to a masked add instruction. For this reason, not all hardware instructions are available as APIs.

CPU feature checks

The package provides global variables to check for CPU features available at runtime. For example, on AMD64, the X86 variable provides methods to check for AVX2, AVX512, etc. It is recommended to check for CPU features before using the corresponding vector operations.

Notes

  • This package is not portable, as the available types and operations depend on the target architecture. It is not recommended to expose the SIMD types defined in this package in public APIs.
  • For performance reasons, it is recommended to use the vector types directly as values. It is not recommended to take the address of a vector type, allocate it in the heap, or put it in an aggregate type.

Functions

func ClearAVXUpperBits 

func ClearAVXUpperBits()

ClearAVXUpperBits clears the high bits of Y0-Y15 and Z0-Z15 registers. It is intended for transitioning from AVX to SSE, eliminating the performance penalties caused by false dependencies.

Note: in the future the compiler may automatically generate the instruction, making this function unnecessary.

func (Uint64x2) CarrylessMultiply 

func (x Uint64x2) CarrylessMultiply(a, b uint8, y Uint64x2) Uint64x2

CarrylessMultiply computes one of four possible carryless multiplications of selected high and low halves of x and y, depending on the values of a and b, returning the 128-bit product in the concatenated two elements of the result. a selects the low (0) or high (1) element of x and b selects the low (0) or high (1) element of y.

A carryless multiplication uses bitwise XOR instead of add-with-carry, for example (in base two): 

11 * 11 = 11 * (10 ^ 1) = (11 * 10) ^ (11 * 1) = 110 ^ 11 = 101

This also models multiplication of polynomials with coefficients from GF(2) -- 11 * 11 models (x+1)*(x+1) = x**2 + (1^1)x + 1 = x**2 + 0x + 1 = x**2 + 1 modeled by 101. (Note that "+" adds polynomial terms, but coefficients "add" with XOR.)

constant values of a and b will result in better performance, otherwise the intrinsic may translate into a jump table.

func (Uint64x8) CarrylessMultiplyGrouped 

func (x Uint64x8) CarrylessMultiplyGrouped(a, b uint8, y Uint64x8) Uint64x8

CarrylessMultiplyGrouped computes one of four possible carryless multiplications of selected high and low halves of each of the four 128-bit lanes of x and y, depending on the values of a and b, and returns the four 128-bit products in the result's lanes. a selects the low (0) or high (1) elements of x's lanes and b selects the low (0) or high (1) elements of y's lanes.

A carryless multiplication uses bitwise XOR instead of add-with-carry, for example (in base two): 

11 * 11 = 11 * (10 ^ 1) = (11 * 10) ^ (11 * 1) = 110 ^ 11 = 101

This also models multiplication of polynomials with coefficients from GF(2) -- 11 * 11 models (x+1)*(x+1) = x**2 + (1^1)x + 1 = x**2 + 0x + 1 = x**2 + 1 modeled by 101. (Note that "+" adds polynomial terms, but coefficients "add" with XOR.)

constant values of a and b will result in better performance, otherwise the intrinsic may translate into a jump table.

func (Uint8x64) StoreSlice 

func (x Uint8x64) StoreSlice(s []uint8)

func (Uint8x64) StoreSlicePart 

func (x Uint8x64) StoreSlicePart(s []uint8)

StoreSlicePart stores the 64 elements of x into the slice s. It stores as many elements as will fit in s. If s has 64 or more elements, the method is equivalent to x.StoreSlice.

func (Uint8x64) String 

func (x Uint8x64) String() string

String returns a string representation of SIMD vector x.

func (Uint8x64) Sub 

func (x Uint8x64) Sub(y Uint8x64) Uint8x64

Sub subtracts corresponding elements of two vectors.

Asm: VPSUBB, CPU Feature: AVX512

func (Uint8x64) SubSaturated 

func (x Uint8x64) SubSaturated(y Uint8x64) Uint8x64

SubSaturated subtracts corresponding elements of two vectors with saturation.

Asm: VPSUBUSB, CPU Feature: AVX512

func (Uint8x64) SumAbsDiff 

func (x Uint8x64) SumAbsDiff(y Uint8x64) Uint16x32

SumAbsDiff sums the absolute distance of the two input vectors, each adjacent 8 bytes as a group. The output sum will be a vector of word-sized elements whose each 4*n-th element contains the sum of the n-th input group. The other elements in the result vector are zeroed. This method could be seen as the norm of the L1 distance of each adjacent 8-byte vector group of the two input vectors.

Asm: VPSADBW, CPU Feature: AVX512
