How to measure memory bandwidth and CPU usage on Blaze T2 + 4470?

Harini Senthilvasan

Customer wants to know  if there is a command line approach to check memory bandwidth and CPU usage during benchmark tests on the Blaze 2 Tablet?  They haven’t found a simple way to measure these metrics during tests.  Thanks for your help.

    Harini,

    Top is a good way to measure CPU usage.  You can just run a command such as:

    # top -m 8 -n 5 -t

    This will show the top 8 processes by CPU usage, for 5 iterations.

    You can use omapconf to access the EMIF statistics collector for EMIF load monitoring, with the command:

    # omapconf trace bw

    This will show the read and write throughput in MB/s.

    Regards,
    Gina
