QNN backend version for 8450

Hello,

I've been successful running example code and a toy model on an 8450 board using the v69 HTP backend (as well as CPU backend for aarch64-android).  I have not been successful with other backends.

1)  It appears that the v66 DSP library, for example, is for a diiferent hardware platform and not applicable in my case.  Is that correct?  So accessing different hardware engines can't be done explicitly through the QNN API(?)

2) What about the HTA backend?  The library is in the SDK but I didn't see any tutorials that use it.

Thanks,

Jeff

Daer developer,

[QC] The dsp arch for SM8450 is v69 only. You need to push related v69 libs no matter for the CPU or DSP.

 

2) What about the HTA backend?  The library is in the SDK but I didn't see any tutorials that use it.

[QC] SM8450 don't support HTA anymore.
