Fast Base64 encoding/decoding with SSE vectorization October 29, 2014 In this installment of "SSE vector programming for fun and profit", we're going to write a Base64 encoder that's about four times faster than everything else available. The results of this process can be found in my ...
首先得到图片的Base64编码的字符串。转化成byte[]数组 String imgData = request.getParameter( "imgData");//Base64的字符串ASE64Decoder decoder =newBASE64Decoder();byte[] imgByte =decoder.decodeBuffer(imgData);for(inti = 0; i < imgByte. length; ++i) {if(imgByte[i] < 0) {//调整异常数...

FastStrings.pas 一个快速字符串处理单元,一些函数用汇编写的,处理速度比DELPHI本身的字符串处理快很多,不过不支持WideString类型。 Idpacker.pas 压缩文件类型检测单元。 ZLibEx.pas 纯Pascal代码的快速压缩解压单元,压缩率和速度都不错。 FastStringFuncs.pas 基于FastStrings.pas单元的应用。

A fast Base64 encoder and decoder as a Ruby gem.How fast? Try it yourself, execute:$ rake benchmark When compared to Ruby's own Base64 module, expect a 4x speedup in encoding, and a 2x speedup in decoding. YMMV.Acknowledgements
We compare SIMD decoding with competitive alternatives. One particularly fast decoder is used by Google Chrome (and available in Chromium). Chromium uses code produced by Nick Galbreath called "high performance base64 encoder / decoder". We also use the decoder found in the Linux kernel as well...
