1 Libjpeg-turbo is a JPEG image codec that uses SIMD instructions
2 (MMX, SSE2, AVX2, Neon, AltiVec) to accelerate baseline JPEG
3 compression and decompression on x86, x86-64, Arm, and PowerPC
4 systems, as well as progressive JPEG compression on x86 and
5 x86-64 systems.
6 On such systems, libjpeg-turbo is generally 2-6x as fast as
7 libjpeg, all else being equal.
8 On other types of systems, libjpeg-turbo can still outperform
9 libjpeg by a significant amount, by virtue of its highly-optimized
10 Huffman coding routines. In many cases, the performance of
11 libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
