I working on customized SoC with ARM Cortex-A9.
It supports NEON, but do not has Mali GPU.
With system, can I use OpenCL with NEON?
I found OpenCL SDK for Mali at ARM website.
( http://malideveloper.arm.com/resources/sdks/mali-opencl-sdk/ )
but there isn't any words support NEON.
ARM have previously announced OpenCL for NEON , but these were not directly available to the public, and the 'opencl-for-neon' link on that page now just redirects to the Mali developer page.
You could instead use pocl , an open source implementation of OpenCL that runs on many different platforms, include ARM CPUs with NEON.
There exist some third party research work on this topic
they created a framework for OpenCL to make use of NEON instructions
