| Hans-G?nter@24691 | 1 Libjpeg-turbo is a JPEG image codec that uses SIMD instructions |
| Hans-G?nter@24691 | 2 (MMX, SSE2, AVX2, Neon, AltiVec) to accelerate baseline JPEG |
| Hans-G?nter@24691 | 3 compression and decompression on x86, x86-64, Arm, and PowerPC |
| Hans-G?nter@24691 | 4 systems, as well as progressive JPEG compression on x86 and |
| Hans-G?nter@24691 | 5 x86-64 systems. |
| Hans-G?nter@24691 | 6 On such systems, libjpeg-turbo is generally 2-6x as fast as |
| Hans-G?nter@24691 | 7 libjpeg, all else being equal. |
| Hans-G?nter@24691 | 8 On other types of systems, libjpeg-turbo can still outperform |
| Hans-G?nter@24691 | 9 libjpeg by a significant amount, by virtue of its highly-optimized |
| Hans-G?nter@24691 | 10 Huffman coding routines. In many cases, the performance of |
| Hans-G?nter@24691 | 11 libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. |
