It is possible to accelerate JPEG compression and decompression by replacing the default libjpeg[1] library with the libjpeg-turbo[2]library that uses the Arm® NEON™ technology.

1 How to check the libjpeg-turbo installation[edit] 

 dpkg -l | grep jpeg
...
Hardware accelerated JPEG compression/decompression library
...

2 How to add the libjpeg-turbo in your distribution[edit]

Please refer to the OpenEmbedded libjpeg-turbo recipe documentation[3]
