= IGEP power consumption measurements === Introduction ==outofthebox->ok
IGEP boards have been designed using low power consumption technologies. Like other embedded devices, some system parameters like: CPU speed, CPU load, peripherals enabled/disabled, Kernel configurations and other ones, can vary its power consumption.----
This article is the result of some analysis implemented to IGEP boards.'''MP3DEC -> DEC MP3 (AUDIO ERRORS)'''
== IGEPv2 boards ==- Followed README file from ISEE - IGEP DSP - GST + DMAI Support Package 3.40.00
