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,
|
2019-12-25 16:24:24 +00:00
|
|
|
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
|
2014-11-21 20:32:31 +00:00
|
|
|
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.
