Hi,

I wonder if there is any tool to profile DDR bandwidth?

For example I can use ‘Perf’ to find the CPU usage of each function in my program.

Is there any similar tool or method for DDR bandwidth on Xavier?

Thanks!

Hi,

I recommend using a valgrind tool called Massif. This tool can be used to measure how much heap memory a program uses, it provides data for each function call and it has a GUI (visualizer). These features are extremely convenient for finding memory leaks for example, you can find more info here: [url]http://valgrind.org/docs/manual/ms-manual.html[/url]
