dc.description.abstract The technology in cellular phones, portable computing systems, intelligent- and connected- devices are evolving in a high pace and in many cases these devices are required to operate in a low-power environment. The problem that continues to emerge, is the power consumption in microcontrollers and DSP devices. This issue has over time become important to solve in order to maximize battery life. To ease the choice of power efficient microcontrollers, controlled experiments were therefore performed with the Cortex-M4, this microcontroller was chosen because of the upgraded hardware, which has led to an appreciable change in both power- and speed efficiency compared to its predecessors. The conclusion presents important points, along with advantages and difficulties to consider when implementing a DSP application. By comparing different optimizations with the Floating Point Unit(FPU), Fixed-point and software Floating-point, the results show that there are major differences in power consumption between these three options. Depending on which option and optimization used then the power consumption can exceed over 70% more compared to the other options available. en_US
