System Design Trade-Offs in a Next-Generation Embedded Wireless Platform
Abstract
Trade Offs in a Next Generation Project.Over the course of the past decade, the evolution of advanced low-energy micro controllers has raised three questions which this System Design Trade-Offs in a Next-Generation Embedded Wireless Platform paper outlines and addresses. The first question is: Can a 32-bit platform be constructed that provides advanced features but fits within the energy constraints of a wireless sensor network? We answer this in the affirmative by presenting the design and preliminary evaluation of Storm – one such system based on an ARM Cortex-M4 that achieves 2.3µA idle current with a 1.5µS wake up time.

Conclusion
This System Design Trade-Offs in a Next-Generation Embedded Wireless Platform paper outlines and addresses three questions posed by the technological advancements of the past decade,showing that:
1. It Embedded System Trade Offs in a Next Generation Project is indeed possible to construct a powerful embedded wireless platform based on a32-bit microprocessor while meeting the energy profile of the current best in-class ultra-low-power “mote”. This is shown by the presentation and preliminary evaluation of Storm – one such system with a rich feature set, and best-in-class energy characteristics.
2. It is possible for the platform to simultaneously cater to the needs of both wireless monitoring and cyber physical systems. We demonstrate the design principles enabling this development, showing that a solder on-module with selectively exported IO is sufficiently versatile to meet a diversity of design points.
3. The use of feature-rich 32-bit processors brings with it new challenges and opportunities for operating system design. Principally we explored the issues of power management, clock distribution, modularity, background operations and supervisory control.
