带有ARM NEON（无Mali GPU）的OpenCL是否可用？

Question

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.

Answer 1

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.

Answer 2

There exist some third party research work on this topic

they created a framework for OpenCL to make use of NEON instructions
