What is Low Power Design?
With today’s environmental considerations and high energy costs Innovent Designs has developed a framework to lower the power consumption of electronic systems.
A poor design can lead to unnecessary current draining operations, excess components, large batteries, increased cooling needs and bulky enclosures. An optimized system reduces complexity while maintaining the desired functionality and performance.
Low Power Design is a process that prioritizes power consumption in its design considerations. It can be applied to any electronic system to optimize the device for its intended use. Every low power design is unique and will have its own set of problems to overcome. Our team has expertise in Low Power Design, utilizing the latest technologies and techniques to lower power consumption – decreasing cost and increasing design options.
How is it done?
Optimizing for power involves more than the selection of low-power components. The goal is to reduce the average quiescent current of the system.
Innovent Designs uses a proprietary framework that analyzes systems for their power properties and identifies areas for optimization. The framework looks at:Static power
Reducing leakage current throughout the system by applying specialized circuit techniques. Optimal component selection is also a key aspect of this optimization step.
Dynamic power
An event driven approach is taken to insure that the system only operates when it needs too. Appropriate scheduling techniques are applied and components are chosen to have quick response times and efficient operating cycles.
Software/Firmware
The greatest power savings may be gained with well written software. We will look at code size optimization, memory access optimization, application of low power arithmetic operators and efficient scheduling techniques.
Other
Innovent Designs provides creative ideas for alternative power sources. We can investigate the feasibility of integrating the latest energy harvesting technologies in cases were ambient energy is available.
Where it applies?
- Battery operated devices
- Size constrained devices
- Devices with extended operating life cycles
- Devices with access to ambient energy sources
- Devices with strict operating specifications (temperature, pressure, humidity etc)
- Devices seeking to reduce their environmental impact
