A multitude of application domains benefit from synchronized multimedia content presentation and playback across spatially scattered client stations. Online remote tutoring, telework and teleconferencing, and the nonco-located synchronous browsing through a digital photo album are merely some examples of potential use cases, which are referred to collectively as real-time distributed groupware....

The matrix converter instability can cause a substantial distortion in the input currents and voltages which leads to the malfunction of the converter. This paper deals with the effects of input filter type, grid inductance, voltage fed to the modulation algorithm and the synchronous rotating digital filter time constant on the stability and performance of the matrix converter. The studies are ...

My main research is on asynchronous and mixed-timing digital design. Asynchronous circuits have no centralized or global clock. Instead, they are distributed hardware systems where multiple components coordinate and synchronize at their own rate on communication channels. As chips grow increasing larger and faster, power and design-time requirements become more aggressive, and timing variabilit...

Malathi Veeraraghavan Mark Karol Polytechnic University Lucent Technologies 6 Metrotech Center 101 Crawfords Corner Road Brooklyn, NY 11201 Holmdel, NJ 07733 [email protected] [email protected] ABSTRACT: The use of connection-oriented (CO) networks for the transport of IP traffic is seen to have value to both users and service providers. Given the expectation that most endpoint-generated traffic will ...

The ITU-T has defined an architecture and requirements for operating an Automatically Switched Optical Network (ASON). The Generalized Multiprotocol Label Switching (GMPLS) protocol suite is designed to provide a control plane for a range of network technologies. These include optical networks such as time division multiplexing (TDM) networks including the Synchronous Optical Network/Synchronou...

A voltage scaling technique for energy-efficient operation requires an adaptive power-supply regulator to significantly reduce dynamic power consumption in synchronous digital circuits. A digitally controlled power converter that dynamically tracks circuit performance with a ring oscillator and regulates the supply voltage to the minimum required to operate at a desired frequency is presented. ...

High-speed intelligent multichannel analogue input/output interface units have been developed at our department by the combination of high-performance digital signal processors with high resolution A/D and D/A converters. The device is able to generate pre-programmed arbitrary signals with the synchronous capture of input signals on eight channels, and is, thereby, ideal for system control and ...

In this paper, a novel architecture for self-timed analog-to-digital conversion is presented, designed using the NULL Convention Logic (NCL) paradigm. This analog-to-digital converter (ADC) employs successive approximation and a one-hot encoded masking technique to digitize analog signals. The architecture scales readily to any given resolution by utilizing the one-hot encoded scheme to permit ...
