RX architecture uses IAR Embedded Workbench

Using power debugging, embedded software can be developed and tuned to save power by exercising stricter control of how and when the hardware consumes power.

Keeping the power consumption down extends battery lifetime in mobile applications and reduces heat dissipation.

IAR Embedded Workbench correlates system power consumption to trace data and the source code, making it possible to analyse how software can be designed to conserve power and discover any power glitches.

Power measurements can be visualised in various ways in IAR Embedded Workbench.

Simultaneous display of power samples, call stack, interrupt activity and variable values on the same timeline maps key events in the execution against power consumption.

Further analysis can be made using the power profiling utility that measures power consumption during the execution of specific functions under specified time intervals.

The power profiling utility provides insight to where efforts should be made to optimise for lower power consumption.

Detailed information about power samples is provided through a live power log.

Power debugging is enabled by an IAR J-Link Ultra emulator probe that provides the hardware connection and power sampling.

A standard IAR J-Link can be used for evaluation of the power debugging technology, but with lower sample rate and resolution.
