Architecture for Efficient Energy Meter

This paper describes a low-power ARM7TDMI based architecture for use in energy meter. Energy metering device demands low power consumption and portable design. It must be able to calculate the energy consumed by a consumer and communicate this calculated data to the a remote central database. To meet this goal, this work proposes an ARM7TDMI based architecture that can be implemented on a single chip resulting in small size and low power consumption, at an enhanced performance. Various low-power and power management schemes have been used in this design. Furthermore, the design nature of this architecture will allow for scalability for further channel additions. :
