## 优化的架构

- **AMD64** SSE/AVX/AVX2

- **ARM64** NEON

- **PPC64X**

- **S390X**

## 性能

关于性能，AMD64下的性能可以参考[English](README.md) 说明，ARM64下的性能请自行测试。另外需要说明的是，解码的时候，如果文本含有回车换行，当前实现没有优势。

本库已经在生产环境运行多时。

## 致谢

本项目的大部分纯Go代码源自 [golang base64](https://github.com/golang/go/tree/master/src/encoding/base64)，本包的使用和Go语言的base64完全相同。

AMD64架构(特别是SSE版本)和ARM64架构的SIMD实现算法源自 [aklomp/base64](https://github.com/aklomp/base64)。
