Hello,
I am using the RK3399proD for purpose on ai research.
I load android 8.1 and trying to use npu with rknn c library.
what i wonder is,
1. when I use rknn_api, does it fully use npu(does npu turn on automatically with boot process)? then Can I profile information such as npu frequency or memory usage?
2. What is npu_powerctrl, npu_transfer_proxy, npu_powerctrl for RK3399proD? Is there the way to communicate with npu?
3. Is there any possible way to use npu not using rknn api but using low level access? I want to use npu computationwisely such as conv, pooling. Does OpenVX can be used for it?
4. Is there the way to add external ddr memory for npu? I think that i saw this can be added from rk3399pro doc.
Thank you.
