Power Management is a key aspect in the design of embedded systems today as it directly affects the battery life and performance of embedded devices. Effective Power Management of an embedded system means building low power designs with lower power consumption, efficient battery management for longer battery life, that provides lowering heat dissipation, increasing system stability ensuring less energy usage, saving cost and reducing the impact on the environment.
Power management and battery management involves hardware design and software development for an embedded system which can efficiently deliver power to all the components in the system. Hardware support is very critical in power management and the software has to exercise the support for good efficiency.
With more than 20 years of experience in hardware design and software development of embedded devices, Mistral’s Product Engineering Services (PES) team has the expertise to implement power management and battery management techniques for designing low power embedded devices.
Power management or Battery management for portable devices can be implemented at different levels; from energy efficient peripherals and adaptive digital systems to power aware software programs. Recent developments in technologies have brought in SoCs with dynamic voltage and frequency scaling capabilities. The main power hogs within the system need not be the microprocessor but the peripherals; and this is where Mistral’s expertise in embedded hardware and software design comes into play! Mistral’s Product Engineering Services has worked with product developers to build low power designs for compact, small footprint, power managed products based on the latest multi-core processors like ARM Cortex A8, A9 and open-source Oses like Android and Embedded Linux.The team has the experience and expertise needed to implement an effective battery management strategy for portable devices. For example: we can choose the right hardware components that can be set to power down modes and enable software to set the hardware modules into different states of activity based on use-case requirements for effective power management.
Mistral’s expertise in low power designs includes implementation of techniques like:
Listed below are some of the low power designs where we have implemented power management and battery management techniques:
