10 Description: A SIMD-accelerated JPEG codec that provides both the libjpeg and TurboJPEG APIs
11 libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate
12 baseline JPEG compression and decompression on x86, x86-64, Arm, PowerPC, and
13 MIPS systems, as well as progressive JPEG compression on x86, x86-64, and
14 Arm systems. On such systems, libjpeg-turbo is generally 2-6x as fast as
15 libjpeg, all else being equal. On other types of systems, libjpeg-turbo can
16 still outperform libjpeg by a significant amount, by virtue of its
17 highly-optimized Huffman coding routines. In many cases, the performance of
18 libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
20 libjpeg-turbo implements both the traditional libjpeg API as well as the less
21 powerful but more straightforward TurboJPEG API. libjpeg-turbo also features
22 colorspace extensions that allow it to compress from/decompress to 32-bit and
23 big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java
26 libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated
27 derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and
28 VirtualGL projects made numerous enhancements to the codec in 2009, and in
29 early 2010, libjpeg-turbo spun off into an independent project, with the goal
30 of making high-speed JPEG compression/decompression technology available to a
31 broader range of users and developers. libjpeg-turbo is an ISO/IEC and ITU-T
32 reference implementation of the JPEG standard.
