Description: A SIMD-accelerated JPEG codec which provides both the libjpeg and TurboJPEG APIs
|
||
|
|
libjpeg-turbo is a derivative of libjpeg which uses SIMD instructions (MMX,
|
||
|
|
SSE2, etc.) to accelerate baseline JPEG compression and decompression on x86
|
||
|
|
and x86-64 systems. On such systems, libjpeg-turbo is generally 2-4x as fast
|
||
|
|
as the unmodified version of libjpeg, all else being equal. libjpeg-turbo
|
||
|
|
also includes a wrapper library which implements the TurboJPEG API used by
|
||
|
|
VirtualGL and TurboVNC.
|
||
|
|
.
|
||
|
|
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
|
||
|
|
performs in the range of 80-120% 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.
