Various industry forecasts project that, by 2020, there will be around 50 billion devices connected to the Internet of Things (IoT), helping to engineer new solutions to societal-scale problems such as healthcare, energy conservation, transportation, etc. Most of these devices will be wireless due to the expense, inconvenience, or in some cases, the sheer infeasibility of wiring them. Further, many...
DRAM consumes a significant amount of energy in mobile computing devices today. Emerging non-volatile memory such as magnetoresistive memory (MRAM) offers a DRAM alternative and can potentially lead to a more energy-efficient memory system. The MRAM technology is already mature, but considering the memory industry is highly standardized, we are still unable to see any MRAM used in mainstream products...
Speculative adders divide addition into subgroups and execute them in parallel for higher execution speed and energy efficiency, but at the risk of generating incorrect results. In this paper, we propose a lightweight correlation-aware speculative addition (CASA) method, which exploits the correlation between input data and carry-in values observed in real-life benchmarks to improve the accuracy of...
