Ultra-low voltage embedded processor system for Internet-of-Things microcontrollers

Abstract

As devices get an ever increasing foothold on the internet and the Internet of Things becomes the usual landscape in the mass consumer electronic products is necessary to bring embedded processors capable of bringing performance to the micro controllers of such devices. compares Is the intention of this project to compare under different scenarios suitable for the applications two embedded processors form Atmel s one AVR 8-bit and an AVR32 UC3 to identify which is the one that has the lowest power consumption, lowest energy consumption. It has been shown that the AVR has the less power consumption(about half) but in terms of energy the AVR32 is less taxing. A test bench was implemented including SPI communication modules and memories,This is due to the long execution times of the AVR which are for 1.5 to 10 longer than the AVR32. These conclusions scale when implementing on lower feature size (this project uses UMC s 130nm typical process library and UMC s 65 typical process library). Also the conclusion stand when restricting the standard library such that an Ultra low voltage friendly net list is produced and tested yielding similar results.
