Implementation of Analytical Tool for Power Analysis in Multi Core Modem

Power consumption in mobile devices is primarily critical because of battery life. It is mainly useful for measuring the performance of the handheld devices as power source has its limitations. Nowadays mobile industries are incorporating multicore modem which implements complex software with hardware. This paper mainly present the method of validating multi-core behavior of modem chip through specifically designed command line interface tool. The command can be given through any terminal like Tera Term/Putty. Through these customized commands, status of each core in modem is known so that power consumption of device can be known. As there is shutdown state, sleep state of a subsystem in the over-all system and also pending interrupts are there, all this can be known by using information of all states and interrupt queues in the modem and hence performance of the power source can be analyzed accurately and effectively.
