RK1808 npu usage information

[复制链接] · 发表于 2021-2-18 19:55:14

Hello, is there a way to check the memory usage, efficiency, clock speed informations for rk1808?

Similiar to the command to check gpu usage in nvidia "nvidia-smi"
I couldn't find anything related to this neither in the forum, nor in your rknn-api documents.

You can check it out by logging into 1808, which is a standard linux.

Command 'cat /proc/meminfo' about checking memory usage.
Command 'cat /sys/kernel/debug/clk/clk_summary' about checking all clock.

I am quite confused. Does rk1808 module not have a separate memory for NPU?
I was under the impression that the module has 1+1 gb memory, 1 gb for cpu, 1 gb for npu. Is this assumption wrong?

https://www.96boards.org/product/tb-96aiot/ => this is my module by the way

Their memory is shared, I did not see the 1g+1g description on the page you provided.

Ohhh, I guess I got confused about their "1GB LPDDR3 / 2GB LPDDR3 " expresion.

So there is only one memory then, thank you
