In the costtable approach to logic design, a given function is realized by selecting functions from a table and combining them. Associated with each function is a cost, and the goal is to find, among all realizations, the one of least cost. We show an extension to the costtable approach in which functions are combined using a multiplexer, with the goal to find an arrangement of the functions th...

Quantum-Dot Cellular Automata (QCA) is a radical technology, which works at Nanoscale. Due to its numerous advantages over the conventional CMOS-based digital circuits, researchers are now concentrating more on designing digital circuits using this technology. Researchers have reported various findings in this field till now. In this paper, a modular 2:1 Multiplexer has been designed followed b...

Quantum-dot cellular automata (QCA) is important technology to be replaced with CMOS. QCA is a new paradigm for digital computing that, theoretically, is expected to reach very high operating frequencies and significant reduction of power consumption. A multiplexer is an important element and it is used in many logic gates and functional circuits. A NAND gate is smaller, area-wise and faster th...

A High Assurance Multiplexer can be used to combine all channels of a MSLS system into a single stream that accommodates all of the channels to be transported at each end of the multiplexed link. The multiplexer/demultiplexer is termed “High Assurance” because it guarantees the integrity of the channel separation process such that, even under multiple failure conditions, the design assures that...

The readout of detector arrays requires the monolithic or hybrid integration of a integrate circuit multiplexer with the detector array. In most LWIR and VLWIR applications, a hybrid approach is used. For example, the detector array may be built from HgCdTe and the readout integrated circuit may be silicon CMOS [1]. The two integrated circuits are mated through a bump-bonding process in which e...

In a previous paper 10] we have shown numerical evidence that there are traac patterns wich generate more loss in a multiplexer than the on-oo source. In this paper we derive mathematical upper and lower bound for two loss measures (P loss , the cell loss rate and P sat , the fraction of time where the multiplexer is saturated) in a buuered multiplexer fed by homogeneous leaky bucket constraine...

Many real-world problems are not conveniently expressed using the ternary representation typically used by Learning Classifier Systems and for such problems an interval-based representation is preferable. We analyse two interval-based representations recently proposed for XCS, together with their associated operators and find evidence of considerable representational and operator bias. We propo...

A 1 by 4 wavelength division multiplexer with 0.5nm bandwidth and no free spectral range limitation is demonstrated on silicon. The device utilizes wide bandwidth filters cascaded with ring resonators in order to select specific ring resonator modes and route each resonant mode to a separate port. This technology will enable dense wavelength division multiplexing covering the C - and L - bands ...

In this paper analyzes various scheduling algorithms applied to multi-media streaming system for providing real-time service in Internet and proposed a scheduling algorithm that can meet the QoS requirements of delay-sensitive traffic and loss-sensitive traffic for specific services. First, the concept of QoS drafted from the recommendation of ITU-T is defined and the requirements for packet mu...
