| Description: A SIMD-accelerated JPEG codec that provides both the libjpeg and TurboJPEG APIs |
| libjpeg-turbo is a JPEG image codec 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 libjpeg, all else being equal. On other types of systems, |
| libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue |
| of its highly-optimized Huffman coding routines. In many cases, the |
| performance of libjpeg-turbo rivals that of proprietary high-speed JPEG |
| codecs. |
| . |
| libjpeg-turbo implements both the traditional libjpeg API as well as the less |
| powerful but more straightforward TurboJPEG API. libjpeg-turbo also features |
| colorspace extensions that allow it to compress from/decompress to 32-bit and |
| big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java |
| interface. |
| . |
| libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated |
| derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and |
| VirtualGL projects made numerous enhancements to the codec in 2009, and in |
| early 2010, libjpeg-turbo spun off into an independent project, with the goal |
| of making high-speed JPEG compression/decompression technology available to a |
| broader range of users and developers. |
