The advanced complexity and heterogeneity of modern telecommunication systems mostly lead to the incorporation of heterogeneous implementation technologies and design styles. Consequently, the design representation of such systems often requires the mixed use of distinct model of computations at different abstraction layers. Therefore, heterogeneous(More)
We present a technique for automatic exploration of architectural alternatives in the design of complex electronic embedded systems and systems-on-a-chip. The technique transforms the problem into a set of simple model-to-model operations and a mapping algorithm that becomes the core of the entire design process. The mapping algorithm is formulated as an(More)
Full-duplex bidirectional transmission at 10 Gb/s is demonstrated for extended wavelength division multiplexed passive optical network (WDM-PON) applications, achieving transmission distances up to 25 km of standard single mode fiber (SSMF) when using a low-bandwidth (approximately 1.2 GHz) reflective semiconductor optical amplifier (RSOA) for signal(More)
An Analogue to Digital Converter (ADC) implemented in CMOS technology (90nm TSMC) is described in this paper which is based on a binary tree structure and has a configurable 4, 8 or 12-bits resolution. The function performed at the nodes of the binary tree is an integer division by a proper power of 2, that is implemented by a novel circuit. The developed(More)
