如何通过JS代码检测浏览器是否支持SIMD？
[英]How do I detect whether a browser supports SIMD by JS code?
问题描述
I found a way to detect but it's not work on my computer with the latest chrome enabling simd flag:
我找到了一种检测方法，但它在我的计算机上无法使用最新的 chrome 启用 simd 标志：
var simd = async () => WebAssembly.validate(new Uint8Array([0, 97, 115, 109, 1, 0, 0, 0, 1, 4, 1, 96, 0, 0, 3, 2, 1, 0, 10, 9, 1, 7, 0, 65, 0, 253, 4, 26, 11]));
await simd();
Is there another way to detect?有没有其他检测方法？

There is an opensource library for wasm feature detection here:这里有一个用于 wasm 特征检测的开源库：
https://github.com/GoogleChromeLabs/wasm-feature-detect https://github.com/GoogleChromeLabs/wasm-feature-detect
The way it works is that it attempts to instantiate a wasm module with the given features, catching an error should it arise (which indicates that the feature is not supported).它的工作方式是尝试使用给定的特性实例化一个 wasm 模块，如果出现错误（这表明该特性不受支持），它会捕获一个错误。
Here's the SIMD module it attempts to create:这是它尝试创建的 SIMD 模块：
