DesignWare IP for Safety & Security Applications
Overview
The Internet of Things consist of both "Brown Field" applications that add wireless to existing devices and "Green Field" applications that describes the proliferation of new innovative devices. Wireless sensor networks will be a driving force in many of these "Green Field" nodes as their underlying technology enables connectivity where energy consumption, installation, and maintenance hurdles were previously too high. A few application examples include smart lighting, locks, fire alarms, parking, pollution, and inventory management.
Reducing power consumption for sensing, actuation, and wireless communications are some of the most important technology advancements. Since extending battery life will be one of the most important features of differentiation, IP that help achieve this will be a critical SoC design decision.
