SIMD.%type%.shuffle()

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The static SIMD.%type%.shuffle() method creates a new SIMD data type instance with the lane values shuffled.

Syntax

JavaScript
SIMD.Float32x4.shuffle(a, b, s0, s1, s2, s3)
SIMD.Float64x2.shuffle(a, b, s0, s1)

SIMD.Int8x16.shuffle(a,b,s0,s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15)
SIMD.Int16x8.shuffle(a, b, s0, s1, s2, s3, s4, s5, s6, s7)
SIMD.Int32x4.shuffle(a, b, s0, s1, s2, s3)

SIMD.Uint8x16.shuffle(a,b,s0,s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15)
SIMD.Uint16x8.shuffle(a, b, s0, s1, s2, s3, s4, s5, s6, s7)
SIMD.Uint32x4.shuffle(a, b, s0, s1, s2, s3)

Parameters

a
An instance of a SIMD type to be shuffled.
b
Another instance of a SIMD type to be shuffled.
s0-s15
Concatenated index of a and b for lane s0-s15.

Return value

A new SIMD data type with the lane values shuffled.

Description

The static SIMD.%type%.shuffle() method shuffles two SIMD data types into one new SIMD data type.

SIMD shuffle operation

Examples

Shuffling a Float32x4

JavaScript
var a = SIMD.Float32x4(1, 2, 3, 4);
var b = SIMD.Float32x4(5, 6, 7, 8);

SIMD.Float32x4.shuffle(a, b, 1, 5, 7, 2);
// Float32x4[2,6,8,3]
