How to accelerate JPEG compression and decompression

Applicable for STM32MP13x lines, STM32MP15x lines

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

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

2. How to add the libjpeg-turbo in your distribution

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