Hello,
I am building and running arm neon code which is generated from matlab. Target device is a78 and it is running on qnx.
I checked the generated code contains arm neon intrinsica and header file. -mcpu option does support a78 exactly so I selected a little lower architecture. Builing is successful but the performance improvement was not observed.
I am wondering that arm neon for a78 in qnx 7.1 is supported or not. How do I check?
Regards,
Junhee
Hi Junhee,
There's a limited amount I can say about 3rd party tools - this is really a question for QNX rather than Arm. However I believe QNX 7.1 was packaged with GCC 8.3. Although GCC 8.3 does support Cortex-A72/A73/A75, it's a little early for Cortex-A78 support.
Paul.
Thank you for reply.
I will contact qnx.
