| Description: A SIMD-accelerated JPEG codec that provides both the libjpeg and TurboJPEG APIs |
| libjpeg-turbo is a derivative of libjpeg that uses SIMD instructions (MMX, |
| SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, |
| x86-64, and ARM systems. On such systems, libjpeg-turbo is generally 2-4x as |
| fast as the unmodified version of libjpeg, all else being equal. |
| . |
| libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but |
| the TigerVNC and VirtualGL projects made numerous enhancements to the codec |
| in 2009, including improved support for Mac OS X, 64-bit support, support |
| for 32-bit and big-endian pixel formats (RGBX, XBGR, etc.), accelerated |
| Huffman encoding/decoding, and various bug fixes. The goal was to produce a |
| fully open-source codec that could replace the partially closed-source |
| TurboJPEG/IPP codec used by VirtualGL and TurboVNC. libjpeg-turbo generally |
| achieves 80-120% of the performance of TurboJPEG/IPP. It is faster in some |
| areas but slower in others. |
| . |
| In early 2010, libjpeg-turbo spun off into its own independent project, with |
| the goal of making high-speed JPEG compression/decompression technology |
| available to a broader range of users and developers. |
