Moore’s Law and Ultra-Low-Power Processors

Moore's Law and Ultra-Low-Power Processors

Welcome to the November/December 2017 special issue on ultra-low-power processors. The Internet of Things (IoT) revolution is happening at a rapid pace. Most projections forecast that the number of connected IoT devices will grow exponentially, easily reaching over 100 billion within the next decade. This revolution leads to a vigorous demand for ultra-low-power (ULP) edge computing devices and...

Guest Editors’ Introduction Ultra-Low-Power Processors

Low-power Fft Processors

In this paper, we present on-going work on the design and implementation of FFT processors with low power consumption.

Hadoop in Low-Power Processors

In our previous work we introduced a so-called Amdahl blade microserver that combines a low-power Atom processor, with a GPU and an SSD to provide a balanced and energy-efficient system. Our preliminary results suggested that the sequential I/O of Amdahl blades can be ten times higher than that a cluster of conventional servers with comparable power consumption. In this paper we investigate the...

An Ultra-Low Power Variable Gain Current Mirror

A power efficient gain adjustment technique is described to realize programmable gain current mirror. The dissipation power changes over the wide gain range of structure are almost negligible. This property is in fact very interesting from power management perspective, especially in analog designs. The simple structure and constant frequency bandwidth are other ever-interesting merits of propos...
