Renesas offers a specialized tool within the DEVKT-P Motherboard, known as the Power Measurement Module (PMM2), enabling precise power consumption monitoring. Capable of measurements as fine as 1 μA, PMM2 excels in discerning power usage nuances across various operational states, including hibernation and sleep modes, where it can achieve accuracy down to 100 nA. This tool, when coupled with digital trigger signals, facilitates granular profiling of software operations’ power footprint, granting invaluable insights into system dynamics.
Alternatively, the use of a power Analyzer like Agilent’s N6705B Power Analyzer presents another avenue for power consumption assessment. Renowned for its reliability and precision, this analyzer offers comprehensive measurement capabilities across diverse device scenarios. The process involves connecting the device under test to the analyzer, configuring settings, initiating measurement, and analyzing real-time readings to discern consumption patterns and inefficiencies, thereby facilitating optimization efforts.
This document outlines the comprehensive preparation required for hardware and equipment to conduct power consumption measurements effectively. It delineates the necessary alterations to parameters and provides guidance on software configuration within the provided examples by Renesas. These steps are crucial for obtaining accurate measurements reflective of real-world use cases.
By meticulously preparing the hardware and equipment, including necessary adjustments to parameters, developers can ensure precise and reliable power consumption measurements. Additionally, thorough instructions on software configuration within Renesas’s examples enable the acquisition of data that accurately represents realistic scenarios. This meticulous approach is essential for gaining insights into power usage and optimizing system performance effectively.
