DesignWare IP for Metering & Smart City Applications
Overview
Cities are implementing WiFi on buses and trains, installing security cameras on busy intersections, and solving complex parking problems using wireless sensor networks. The Internet of Things will transform how smart cities interact with residents.
Meters have improved in accuracy and precision as well as increased the number of installations, which dramatically enhances our ability to manage and conserve resources. However, these meters must be cost effective to justify their installation and maintenance over the useful life of the device. Reliability, overall cost of ownership, as well as accuracy and precision all play important roles during the design of metering SoCs. 草榴社区 offers a broad range of IP that meets the area and power requirements for metering applications.
