While a communication network is a critical component for an efficient system-on-chip multiprocessor, there are few approaches available to help with system-level architectural exploration of such a specialised interconnection network. This paper presents an integrated modelling, simulation and implementation tool. The network architecture can be… (More)
Energy-efficient embedded systems rely on domain-specific coprocessors for dedicated tasks such as baseband processing, video coding, or encryption. We present a language and design environment called GEZEL that can be used for the design, verification and implementation of such coprocessor-based systems.The GEZEL environment creates a platform simulator by… (More)
Summary form only given. While a communication network is a critical component for an efficient system-on-chip multiprocessor, there are few approaches available to help with system-level architectural exploration of such a specialized interconnection network. We present an integrated modeling, simulation and implementation tool. A high level description of… (More)
Wideband digital-to-analog converters (DACs) are key to future high performance military electronic systems. This paper presents the results of an ultra wideband DAC based on advanced InP DHBT technology. The chip integrates a 40-to-10 bit digital multiplexer with a 10-bit DAC and associated clock generation.
Gigahertz-rate Digital-to-Analog Converters (DACs) have become readily available from several commercial vendors but have been unable to achieve >;70 dB spurious-free dynamic range (SFDR) performance over a wide bandwidth (≥500MHz). This paper presents the results of a unique, heterogeneously-integrated (InP HBT with 0.18um silicon CMOS), 13-bit… (More)
This paper describes the development of analog-to-digital converters (ADCs) providing high dynamic range for multi carrier, multifunction communication applications. The ADCs are high order lowpass and bandpass delta-sigma modulators implemented in indium phosphide (InP) heterojunction bipolar (HBT) technology.
