On such systems, libjpeg-turbo is 15 generally 2-6x as fast as libjpeg, all else being equal. On other types of 16 systems, libjpeg-turbo can still outperform libjpeg by a significant amount, 17 by virtue of its highly-optimized Huffman coding routines. In many cases, the 18 performance of libjpeg-turbo rivals that of proprietary high-speed JPEG 19 codecs. 20 . 21 libjpeg-turbo implements both the traditional libjpeg API as well as the less 22 powerful but more straightforward TurboJPEG API. libjpeg-turbo also features 23 colorspace extensions that allow it to compress from/decompress to 32-bit and 24 big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java 25 interface. 26 . 27 libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated 28 derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and 29 VirtualGL projects made numerous enhancements to the codec in 2009, and in 30 early 2010, libjpeg-turbo spun off into an independent project, with the goal 31 of making high-speed JPEG compression/decompression technology available to a 32 broader range of users and developers. 33
