hello Mace DSP is based on hexagon nnlib, what is libhexagon_controller.so used for? where is the source code for libhexagon_controller.so ?

thanks very much.

@huanyingjun libhexagon_controller.so is used to link with MACE to call stub routine of nnlib. You can find more info from here.

@lee-bin 感谢您的回复用mace跑DSP需要手机有root权限并将libhexagon_nn_skel.so push到 /system/vendor/lib/rfsa/adsp/

我对比了tflite，tflite hexagon delegate不需要手机root权限，可以将libhexagon_nn_skel.so push到手机的任意目录，然后在代码进行相应设置就可以了。 Mace是否也可以增加类似功能？这样调式DSP会方便很多。

tflite 设置DSP路径代码 dsp

可以的，用ADSP_LIBRARY_PATH设置libhexagon_nn_skel.so目录即可。
