Modeling synchronous systems in BIP

We present a general approach for modeling synchronous component-based systems. These are systems of synchronous components strongly synchronized by a common action that initiates steps of each component. We propose a general model for synchronous systems. ...

A Current Sensing Completion Detection Method for Asynchronous Pipelines Operating In the Sub-threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime the circuit delay, and hence, the leakage energy consumption depend on the supply voltage exponentially. By re ...

Energy efficiency enhancement of sub-threshold digital CMOS

Omer Can Akgun

Power density and energy dissipation of digital IC's has become one of the main concerns during the recent years. With the increased usage of battery powered devices, ubiquitous computing, and increase in implantable biomedical applications, enhancing ener ...

Energy Efficiency Comparison of Asynchronous and Synchronous Circuits Operating in the Sub-Threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime circuit delay, hence the leakage energy consumption depends on the supply voltage exponentially. By reducing t ...

Synchronous and Asynchronous Multiplexer Circuits for Medical Imaging Realized in CMOS 0.18um Technology

Rafal Tomasz Dlugosz

Multiplexers are one of the most important elements in readout front-end ASICs for multi-element detectors in medical imaging. The purpose of these ASICs is to detect signals appearing randomly in many channels and to collect the detected data in an ordere ...

Improving Application Performance by Dynamically Balancing Speed and Complexity in a GALS Microprocessor

Microprocessors are traditionally designed to provide “best overall” performance across a wide range of applications and operating environments. Several groups have proposed hardware techniques that save energy by “downsizing” hardware resources that are u ...

Synchronous System and Perfect Failure Detector: solvability and efficiency issues

Rachid Guerraoui, André Schiper

Keywords: distributed systems, fault-tolerance, consensus, efficiency, synchronous system, asynchronous system, failure detector. We compare, in terms of solvability and efficiency, the synchronous model, noted S_S, with the asynchronous model augmented wi ...

Floodnet, design and throughput

Claude Petitpierre

The author discusses a newly introduced local area network concept that provides a very interesting alternative to the bus and ring networks. He proposes a new type of node that can be integrated into a meshed configuration. This node is composed of severa ...
