Tools and Modeling

Energy Efficiency Target

There is no single power reduction technique that is able to meet all the system requirements for energy minimization. The trick is to effectively combine architectural, platform and circuit techniques, system and application software, process technology and design methodology and tools to intelligently develop semiconductor designs that deliver the highest possible performance levels within a restricted energy budget. The Freescale Energy Efficiency Target illustrates how these technologies and techniques are integrated into the full development process designed to achieve optimal energy efficiency.
