    That amount of memory usage is not unusual and depends on how your system is configured. The following post discusses the amount of memory used by the Linux kernel and has some tips about reducing memory usage: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/7946/141479...
