EnergyTrace+TM technology
• Provides a complete ecosystem for real-time power debugging and quickens time to
market. Spends less time debugging and more time developing.
• Graphical User Interface in TI’s Code Composer Studio integrated development
environment (IDE) and IAR Systems’ Embedded provides energy profiles of your
application
– Current measurement and CPU states can be tracked over time to help identify
power black holes
