- 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, AltiVec) to accelerate baseline JPEG compression and decompression on
- x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is
- generally 2-6x 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.
