We consider a Machine-to-Machine (M2M) network where a large number of user nodes (STAs) communicate with a Data Collector (DC). We consider the case where all the user nodes periodically transmit their data packets to the DC and the network is in saturation. Recently protocols based on Frame Slotted Aloha (FSA) have been shown to be suitable as MAC protocols for M2M data collection networks under...
This paper describes an architecture and FPGA synthesis tool chain for building specialized, energy-saving coprocessors called Irregular Code Energy Reducers (ICERs) for a wide range of unmodified C programs. FPGAs are increasingly used to build large-scale systems, and many large software systems contain relatively little code that is amenable to automatic, semi-automatic, or even manual parallelization...
Complex “fat operators” are important contributors to the efficiency of specialized hardware. This paper introduces two new techniques for constructing efficient fat operators featuring up to dozens of operations with arbitrary and irregular data and memory dependencies. These techniques focus on minimizing critical path length and load-use delay, which are key concerns for irregular computations...
This article discusses about Greendroid mobile Application Processor. Dark silicon has emerged as the fundamental limiter in modern processor design. The Greendroid mobile application processor demonstrates an approach that uses dark silicon to execute general-purpose smart phone applications with less energy than today's most energy efficient designs.
