SIMD

Single Instruction, Multiple Data

This extension exposes SIMD SSE instructions for use in PHP ... for whatever reason you like ...

<?php
class SIMD\Float32x4 {
	public function __construct(float $x, float $y, float $z, float $w);

	public function add(Float32x4 $v);
	public function sub(Float32x4 $v);
	public function div(Float32x4 $v);
	public function mul(Float32x4 $v);
	public function min(Float32x4 $v);
	public function max(Float32x4 $v);
	public function and(Float32x4 $v);
	public function andNot(Float32x4 $v);
	public function or(Float32x4 $v);
	public function xor(Float32x4 $v);
	
	public $x;
	public $y;
	public $z;
	public $w;
}
?>

Operators

The following operators will work on Float32x4 vectors as expected:

• + -> addition
• / -> division
• * -> multiplication
• - -> subtraction
• | -> bitwise or
• ^ -> bitwise xor
• & -> bitwise and
• ~ -> bitwise not

Enjoy folks ;)
